BMW X3 airbag fault warning light flashes sometimes riding indoor lighting

An approximately 160,000 km mileage 2004 BMW X3E83SUV. Users report: car instrument airbag fault warning lights, cab lights sometimes flicker, front and rear wiper operation weakness, often stuck in the middle of the glass does not move.

After the pick fault content is read by ISID :50-MRS supply voltage; 8C-KOMBI moldings R; 87-KOMBIK bus; 30-GMK bus. Failure to read the content from the perspective of the detector in addition to “50-MRS supply voltage” Others are more abstract failures content, Symptom vehicle from the surface nothing seems implicated, so he decided to choose the airbag fault first, the phenomenon of exclusion. Select “50-MRS supply voltage” testing program execution, inspection program first analyzes the fault stored in the memory of the memory voltage is too low, if the supply voltage exceeds the 20s MRS is less than 9V, MR will store this fault, where MRS is the airbag The control unit or multi-occupant protection system control unit. Continue the inspection program, the detector gives a circuit diagram of the airbag system shown in Figure 1, and is recommended to check the battery voltage, battery check circuit diagram of a voltage with a voltage of 12.8V, normal. Tips for inspection in accordance with the circuit diagram of F11 MRS insurance, the insurance did not fuse. In accordance with the test plan to continue down analysis, whether between MRS supply terminal X74 of 57 feet and a ground supply voltage 9 ~ 16V, using a multimeter to measure voltage 57 between the foot and the ground terminal is only 5 ~ 8V, followed by measure the voltage X10016 22-pin terminal, F11 insurance and ground, the result is only 5 ~ 8V, it is clear that there is power failure MRS. MRS is powered by the battery through the ignition switch provides direct R block, as shown in the ignition switch in the position of a radio block diagram of the F11 is the insurance supply terminal R block shown in Figure 2. R-side airbag system not only to the insurance F11 power, but also for several systems powered A1 fuse distributor of F5 ~ F15’s. Since the F11 is only 5 ~ 8V supply voltage, and that several other insurance system is not only 5 ~ 8V supply voltage it? Measurements and inferred as, F5, and several fuses are also only 5 ~ 8V supply voltage. View schematics to find the fuse F9 is powered body basic module, and flying fuse wiper relay is controlled by the body basic module for the interior lights powered F6. Symptom several vehicles, seemingly unrelated, are actually the cause of the power supply voltage is too low skp-900.

R block is rotated by a mechanical key mechanical ignition lock, ignition switch by changing the linkage of internal contact position control, a common cause of failure is mostly inside the ignition switch contacts wear or erosion caused. To verify the empirical analysis is correct, the maintenance staff while measuring the voltage at A1 distributor, while shaking the ignition switch, then found Al multimeter measured at the supply voltage constantly varies between 5 ~ 11V, then check to make sure the ignition switch after the connection terminal is no problem, indeed the point of failure is the ignition switch.

Replace the ignition switch, troubleshooting.This story originally appeared on

How to understand car odes by obd2 scanner

I just read the news release sent over to us by our friends at ASA (Automotive Service Association) announcing that Sen. Jay Rockefeller (D-W.Va.), chairman of the Senate Commerce Committee, introduced S. 2559, a bill to expand the National Highway Traffic Safety Administration’s (NHTSA) authority to recall unsafe vehicles and increase funding for automobile safety. (Read the full release here)

Obviously, this is in response to the massive GM (and other) recalls we’ve been seeing over the last several months. But will it really improve vehicle (and occupant) safety or does it only address the aftermath? And what about the safety issues that the consumers themselves allow to happen?

If you work on cars for a living, especially in a state with no mandatory vehicle safety inspection program, you know what I’m getting at. I can’t count the number of times I’ve lifted a vehicle up in the air to find bald tires, worn out brakes and seriously loose steering/suspension components. And how many cars do you see every day that are missing one or more brake lights, or are driving down the highway with shattered windshields?

I’m not usually an advocate of government intervention, but in this case I think we need to lobby for more. We need a uniform safety inspection program across this country to protect the innocents. Hey, if someone want to drive around on bald tires with no brakes, I don’t want to hear it when they come crying after the crash. That is their individual choice and if they were driving alone on the road, I would have no problem with it and couldn’t care less.

But these drivers don’t drive alone. Their kids are in the backseat and they are driving in front, behind or beside my family and yours. Their blowout could injure others who had no say so in their choice to drive an ill-maintained car.

Driving is not a right, it’s a priviledge. If they can’t afford to keep their cars safe, then I’m sorry…that’s too bad. Take a bus instead. And regulation of some sort is needed to make sure that the roads are safe for everyone. At least as safe as we can make them.

Second-generation OBD-II market to grow

MOUNTAIN VIEW, Calif. (July 2, 2014) — The entry of device makers, app developers, telecom providers and system integrators into the automotive aftermarket will power the growth of second-generation on-board diagnostics, or OBD-II, services to a $1.6 billion industry across North America over the next five to seven years, according to Frost & Sullivan Inc.

The research firm predicts “parts and service suppliers will soon scramble to align themselves with OBD-II subscription providers to avoid being left out of the ‘connected vehicle’ space.”

With OBD-II, consumers can receive notifications when a part is failing, schedule to have their vehicle repaired at a nearby garage or even purchase their spares online. Once fitted into the car, the OBD-II receiver can transmit data through embedded cellular features or via Bluetooth/Wi-Fi interaction using the driver’s smartphone.

The independent aftermarket must act soon because of the high installation of embedded telematics systems designed to route vehicle owners back to the nearest franchised dealership, presenting a potential threat to distributors, service chains, independent repair facilities and parts retailers, according to Frost & Sullivan.

OBD-II systems have been a requirement for all light-duty cars and trucks since the 1996 model year.

Frost did not specify the size of the market or what percentage of growth it expected to see in the next several years.

The Mountain View-based research firm did say that with the growth of telematics platforms in modern vehicles capable of sending and receiving data, OBD-II has spawned a device and service industry allowing consumers to purchase user-based insurance, monitor their driving behavior and track their car or truck in the event of a theft, among other possibilities.

Smartphone app developers are also becoming more active, with programs using a vehicle’s Bluetooth receiver to transmit data collected from the growing network of sensors and computers found on modern automobiles.

User-based insurance (UBI) accounts for about 90 percent of total OBD-II services revenue, according to Frost. However, a wide range of fleet management services—including prognostics, driver monitoring and vehicle tracking, among others—will eventually propel the growth of OBD-II among companies, as well as consumers.

Major developers, including Danlaw, Delphi, Voxx International, CarShield, Automatic, Zubie, Carvoyant, Dash Labs and Mojio, are creating new business models and subscription services to differentiate themselves, Frost said.

The biggest challenge facing solution providers are the OEMs, which have a head start with products—such as General Motor Co.’s OnStar and Ford Motor Co.’s SYNC systems—that already have gained acceptance among tech-savvy drivers.

As of now, devices are priced around $100 for consumers, with subscription fees ranging from $5 to $10 per month, Frost said

Make travel worry-free maintenance of automotive shock absorbers Troubleshooting

The role of shock absorber is to ensure that when cars with adequate stability, and shock absorbers with health or life of the vehicle has a very important relationship, so each owner should understand the relevant knowledge of some of the shock absorber, and when the shock absorber failure should be how to overhaul.

Check that the damper in good condition:

1 so that the poor condition of the car on the road after driving 10km road parking, touch shell shock absorber, if not hot enough, indicating no resistance inside the shock absorber, shock absorbers do not work. At this point, you can add the appropriate oil, then test, if the shell fever, compared with an internal shock absorber oil, should add a little oil; otherwise, indicating damper failure.

2 Press firmly bumper, then release, if the car has 2 to 3 times jump, then the shock absorbers work well.

3 When the car slowly driving and emergency braking if the car more violent vibration, indicating a problem with the shock absorber.

4 Remove the shock absorber to be upright, and the lower end of the connecting ring in the vise clamp, pull compression damping lever several times, then there should be a stable resistance, pull up resistance should be greater than the downward pressure when resistance, such as resistance to unstable or no resistance, may be short of oil inside the shock absorber valve parts or damaged parts should be repaired or replaced.

In determining the shock absorbers have a problem or failure, it should first check whether the shock absorber oil spills or traces of old oil spills.

If there is no oil leakage phenomenon shock absorbers, shock absorbers should check the connecting pins, connecting rods, connecting hole, rubber bushings and other damage, sealing off, break or fall off place. If the examination is normal, should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without strain, the valve seal is good, valves and valve seat are tight fitting and less Zhen’s done spring is too soft or broken, take grinding ways repair or replacement under the circumstances.

Further, the damper in actual use will be a beep failure, which is mainly due to the damper spring, frame or shaft collision damage or loss, and a cushion cylinder deformation damper dust, oil lack of other causes, reasons should be identified, to be repaired.

After the shock absorber during the inspection repair should be carried out in a special test bench performance tests, when the resistance frequency in the 100 ± 1mm, its resistance to stretching and compression stroke stroke should be specified.

Mercedes is giving budding filmmakers the chance to direct James Corden in new #CLAstory online film

A new initiative from Mercedes is using the four-door CLA coupe to help inspire fledgling filmmakers.

Called the #CLAstory and run via a microsite of the same name, the social media-led programme is inviting budding directors to contribute scenes for an online film starring actor and writer James Corden.

Three high-profile users of picture sharing site Instagram have provided the basic outline of the story, each having individually collaborated with Mercedes to create their own short film. These separately form the beginning, middle and end of the storyboard, leaving a total of six scenes missing and in need of filling.

Anyone can submit an entry to Mercedes UK’s Instagram channel for consideration, with a winning entry selected for all six of the segments awaiting completion. Following this, an overall winner will be determined by a public vote, and the successful film’s creator will be offered the chance to direct comedian James Corden in their #CLAstory.

He’ll star alongside the Mercedes CLA AMG Sport, and the end product will appear online on both the campaign’s dedicated website and social media. The successful filmmaker will also receive a Go Pro camera, as will the five runners up.

The final submission date for entries is July 6, shortly after which voting will open to decide the Grand Prize winner.

Who moved my car to explore the safety car networking

Previously, the car is isolated, physical isolation, and therefore difficult to remote hacker intrusion inside the car computer (ECU), unless physical invasion, and this is the high cost of crime needs. With the Internet’s evolution, when golo3 this car networking products through OBD (On Board Diagnostics) diagnostic socket inside the car ECU networking, remote network attacks by the car is no longer a suspect. It can be predicted that once the popularity of car networking products, cars were attacked on actual cases and more and more will appear.

Just look at the cars on the highway are artificially controlled engine suddenly stalled, will be like a finale? You scared yet?

An OBD diagnostic seat and topology ECU

Before the safety car networking discussed in detail, first we have to understand the next OBD diagnostic seat, below the SAE J1962 standard definition of OBD diagnostic seat:


OBD diagnostic seat is one that contains the female 16pin, pin definitions given in addition to the figure, the other did not give the pin by car manufacturers own definition. ECU different communication protocols may use different pin, KWP (key word protoctol) keyword is used in the 7th protocol pin or 15-pin, the most common 500kbaud of iso15765 protocol (high-speed CAN) uses 6 No pin and 14 pin. OBD diagnostic socket is generally located below the steering wheel, different models may not be the same as the specific location, the following figure shows the specific location of the Toyota Camry 2011 classic version of OBD diagnostic seat:


Next we need to understand the topology between the ECU and the ECU. ECU (Electronic Control Unit) electronic control unit, the popular saying, it is actually used to control the number of records or change the status of the car, or ARM microcontroller chip. Now, there will be general automotive interior dozen to several dozen ranging ECU, ECU different charge different modules, such as the engine control module (PCM) will accept the sensor signal, through complex calculations to control the supply of fuel, Air rationing (electronic throttle), fuel injection and ignition timing, intake air pressure adjustment, but also according to temperature, load, knock, combustion conditions and other factors to determine the compensation control engine. According to different functions, we can put ECU into power, body, chassis, other other categories. The following table lists the high profile of the 2011 classic version of the Camry some ECU module.

In addition to automotive interior ECU, there will be a large number of sensors and actuators and other components, through their joint coordination complex intelligence operations. ECU and then the ECU, ECU and other components is how to communicate it? Topology is as shown between the various components of the vehicle interior

Actual situation more complex than the above figure, there are also differences between the different models, may also occur between the various components are connected directly, the whole principle is about the same, equal to connect all components on the CAN bus. CAN bus with low cost, high bus utilization, physical characteristics and reliable fault tolerance, high-speed transfer rate. It is based on a broadcast format, meaning that any node on the same bus to the bus message, other nodes on the bus can receive the message, then the message according to the head to determine whether a message is sent to their own . Accomplished through a gateway between different baud signal adaptation bus.

OBD II diagnostic socket by what we can do

We know OBD diagnostic seat is designed to be used in automotive diagnostic, it is the only interface to interact with the outside automotive ECU, that we can do auto diagnostic equipment can do, let’s take a look at the diagnostic line with market requirements instrument should have the function:

1 automotive ECU can read information, such as 17 vin code, ECU hardware information.

2 can read the current state of the car, such as current speed, tire pressure and so on.

3 can read fault codes of the car, the car quickly locate the fault location and clear fault codes.

4 cars be able to conduct a pre-set number of actions tests. Such as window lift, etc.

5 In addition to these basic diagnostic functions, may also have the power brush, odometer changes, key match, airbag reset other complex special features.

In addition, we know that the form is based on the CAN bus to transmit the broadcast message and when the message is sent to the CAN bus, the ECU receives this message is unable to determine from which node the message is sent, i.e., the message does not contains the source address or destination address, the message header is just an identifier, ECU is only based on the identifier to identify whether it is sent to their own. This design flaw will naturally lead to message forgery and spoofing attacks. OBD diagnostic seat as a node on the bus, not only to monitor the CAN bus at the news, but also to forge a message (such as sensor messages) to deceive the ECU, so as to achieve the purpose of changing the state of the car behavior.

Taking these two cases, we can put a message on the CAN bus is divided into the following two categories:

1 message communication between diagnostic and automotive ECU called a diagnostic message.

2 messages for communication between automotive interior components called inside information.

Any kind of message sequence defined above by carefully constructed bus, a malicious attacker could change state sent to the car.

Here you can enumerate the consequences brought about several attacks and attacks. For example, a malicious attacker can send a message through a sequence of body systems to unlock car doors and trunk, so as to achieve the purpose of stealing property owners; another example, an attacker can construct a sequence of messages sent to the OBD diagnostic seat to force the vehicle to run on high-speed turn off the engine, so as to achieve the purpose of the car crash.

Three ways to attack the car networking

An element of any communication between the elements and the OBD car from the cloud server networking products, mobile APP, a box of three basic elements, attack them, are able to drive networking devastating blow. I include here a few points:

1. Diagnostic data logic invasion cloud service side, the service side of tampering, to change the behavior of the car purpose

2. Informed communication logic between the phone and the box APP through reverse engineering, pseudo-vehicle networking products resulting sequence of messages sent to mobile phone APP box malicious.

3 attacks via WIFI, Bluetooth communication channels and so on….
