1 | Fault code | |
2 | Fault storage Activation of malfunction indicator lamp for engine diagnosis (EURO3/4) or CHECK ENGINE (MIL) | after the end of the test period and faults after two successive driving cycles with faults |
3 | Frequency of the test | continuous |
4 | Checked signal or status | Supply voltage for valves |
5 | Fault setting conditions Lower limit Upper limit |
approx. 8.5 V (longer than approx. 0.1 s) approx. 15 V (longer than approx. 0.1 s) |
6 | Test sequence | The valves are supplied with battery voltage by 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 detected by the ETC control module and sent via the CAN data bus to the ME-SFI control module. The faults are stored and the malfunction indicator lamp is activated by the ME-SFI control module. Also read out ETC diagnostic trouble code memory, fault code 10. |
