Phenomenon: Mercedes-Benz 600SEL sedan, instrument panel ASR (snow anti-skid) fault light is always bright. By understanding, the fault just appeared, after a period of time after the ASR fault light will be lit; turn off the car and then restart, the dashboard ASR fault lights will be extinguished; but then travel for some distance, ASR fault lights will be re- Lit.
    Maintenance: ASR fault on the dashboard is always on, indicating that the car ASR system is faulty. ASR system known as the snow anti-skid control system, also known as drive anti-skid control system, generally with the ABS system are integrated, collectively referred to as anti-skid control system
    First ASR system using the vehicle fault self-diagnosis function from the fault detection socket on the ASR system fault code, the error code shows: ASR computer and EGAS (electronic throttle control system) computer signal transmission problems. The EGAS system for fault self-diagnosis, retrieve the fault code, but can not read any information. So it is suspected that the line is faulty. After careful inspection of EGAS computer line system, did not find any unusual phenomenon. Open the EGAS computer, found EGAS computer which has an integrated block has been burned. Need to replace, replace the EGAS computer after the test, ASR fault light is no longer lit, but the road test a distance, ASR fault lights and light up. And then use the vehicle fault self-diagnosis system to extract the ASR system fault code, fault code shows: bad contact line bad (the original ASR system and EGAS system signal transmission bad).
    Check the idle contact line (Mercedes-Benz car idle contact mounted under the accelerator pedal) and found that the idle contact line has a line plug open, the line plug, test, ASR fault light is no longer lit, the fault completely ruled out The
