1 | Fault code | |
2 | Fault memory and actuation of CHECK ENGINE (MIL) | After two consecutive journeys with fault |
3 | Monitoring time and frequency of testing | Continuous |
4 | Checked signal or status | Supply voltage, valves |
5 | Lower limit value Upper limit value | < battery voltage 2 V (for more than approx. 0.1 seconds) > battery voltage +2 V (for more than approx. 0.1 seconds) |
6 | Test sequence | The valves are supplied with battery voltage from the ETC control module. The difference between battery voltage and the supply voltage to the valves is monitored by the ETC control module. |
7 | | Faults are recognized by the ETC control module and conveyed to the engine control module (ME-SFI) via the CAN data bus. The engine control module (ME-SFI) carries out fault memory and actuation of CHECK ENGINE (MIL). Also read out the ETC fault memory, fault code 10. |
