With Mercedes-Benz and BMW carry on domestic product sales produced Mercedes-Benz and BMW cars is growing quickly. Mercedes-Benz and BMW during the domestic hot at the same time, sales of imported Mercedes-Benz and BMW can also be climbing. At present, Mercedes-Benz and BMW's total holdings have been significant, with all the corresponding maxidas ds708 level of servicing is consistently expanding, Mercedes-Benz and BMW engaged in upkeep function staff can be expanding. Right here to share about a single BMW fix situation.

Symptom: down to the bottom on the left rear in the vehicle; handbrake dashboard lights lit, electronic parking brake failure

Troubleshooting: diagnostic laptop linked to your motor vehicle diagnostic laptop displays fault codes.

6011 Handle Unit: internal failure (engine circuit)

600E EMF handle power: internal fault (motor circuit)

6EBD DSC: EMF: Interface

5F9A EHC enhanced regulation time fault

Double-click the fault code and uncovered that all fault codes are presently exist, you are able to identify EMF and EHC technique has faults, decided to verify the EHC failure.

Click within the check vehicle, enter EHC (single axle air spring) management unit, management unit to the motor towards the left rear air springs inflated, inflated at the left rear wheel was located a significant leak sound by the computer managed automobiles will rise, discovered Left rear air spring has obvious cracks, hand cracks, air leaks, make sure the air spring is result in injury for the left rear with the car to reduce the reasons, we recommend customers to exchange the air springs.

Then carry on to use the computer system to detect EMF module into testing plan, there exists a hint about EMF wiring harness, the content material is in E71 automobiles shipped just before July 2009 on EMF defective wiring harness, if your set up just isn't standardized, it'll trigger harness put on. Stick to the prompts to the ISTA verify harness for EMF and uncovered no irregularities and dress in installation in which end testing system.

Enter EMF management unit: Internal fault detection scheme EMF detection Digiprog 3 and handle unit can talk with the management unit for testing and located no other signs, flip off the ignition switch, pull the plug, check the pin, non-destructive harm. Measuring power and ground pins within the plug with a multimeter, measure the outcomes correctly. At this time you are able to figure out EMF management unit is broken, we endorse buyers to exchange EMF control unit.

Fault Summary: The over two faults in BMW cars are much more popular faults and failures while in the two systems, the program framework is comparatively straightforward, the issues of failure diagnosis is not higher, but shell out awareness for the specs from the assembly , e.g. an air spring conduit set up, EMF harness installation. If your installation is not really linked to the hardware specs will induce injury or shorten the updated component shelf life.
