With mileage of about 106,000 km, configuration M272 engine, transmission 722.9 Benz R350. The vehicle is parked for too long because the loss of electricity caused by the battery, causing the vehicle can not be started. Owners to help foreign aid, since the outer repair shop master when to take power battery positive and negative operational errors, resulting in a vehicle fails to start, had to drag the service station to check.

     Troubleshooting: EIS can be switched on when the key is inserted on the 15th circuit, displayed on the meter, "Do Guadang, to service and repair the" red warning message and "ESP is currently no such function" white information, the EIS is screwed to 50 starting block the starter does not turn. Current operating selector lever in gear ineffective.

    Benz Star C3 is connected DAS diagnostic rapid test vehicle showed that key information.

    As can be seen from the rapid detection of single, current vehicle has a plurality of control modules and DAS diagnostic unable to communicate, analyze the cause of failure is due to take power, it should be the main power circuit supply failure. The principles of the easier issues first, first measure the right front of the engine compartment fuse relay boxes off the main power supply, no voltage found here.

    The investigation related wiring diagram that is accountable to the front right of the engine compartment fuse box F58 relay power components for the front portion of the pre-fuse box F32 fuse No. 8. F32 front portion of the pre-fuse box located in the engine compartment on the right front inlet air conditioning.

    F8 found by measuring the fuse has blown, refitted with type fuse test, troubleshooting.

    Fault Summary: This is a typical vehicle power supply system failures, failure to understand the context of models circuit diagram for the troubleshooting can play a multiplier effect.
