| Traction systems (ABS, ASR, ETS) and SPS diagnosis, advanced information | AD42.00-P-2000A | ||
| Troubleshooting | |||
| Complaint | Possible cause | Notes | Remedy/Test step |
| ASR MIL (A1e22) or ETS MIL (A1e35) or ABS MIL (A1e17) illuminated with engine running | Read out fault memory AD42.00-P-4000A |
||
| ASR MIL (A1e22) or ETS MIL (A1e35) or ABS MIL (A1e17) comes on while driving and does not go out again | Read out fault memory AD42.00-P-4000A |
||
| ASR MIL (A1e22) or ETS MIL (A1e35) or ABS MIL (A1e17) comes on while driving and goes out again | On-board voltage <11 V, too many electrical consumers in operation | Test generator (G2), read out fault memory AD42.00-P-4000A |
|
| Brake pad wear indicator lamp (A1e6), low brake fluid level/parking brake indicator lamp (A1e7), ASR warning lamp (A1e21), ETS warning lamp (A1e36), ABS MIL (A1e17), ASR MIL (A1e22) or ETS MIL (A1e35) not illuminated when ignition switched on | Instrument cluster data bus (on instrument cluster without CAN connection only) CAN data bus (on instrument cluster with CAN connection only) |
AD42.00-P-4000A Read out instrument cluster fault memory |
|
| ABS MIL (A1e17) illuminated with engine running after brake or roller dynamometer | Implausible speed signal due to different speeds at front and rear axle | Read out and erase fault memory AD42.00-P-4000A |
|
| ETS only: ETS MIL (A1e35) comes on while driving and goes out again after some time (Fault C 15 12 is stored) | Rear wheel brake was temporarily overloaded | Read out and erase fault memory AD42.00-P-4000A |
