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 | Activation of modulating pressure control solenoid |
5 | Fault setting conditions Short circuit to ground Lower limit, voltage Upper limit, voltage Lower limit, current Upper limit, current Test duration |
< 0.4 V approx. 8.5 V approx. 15 V approx. 0.300 A approx. 0.700 A approx. 1 s |
6 | | Faults (activation of line interruption or short circuit, short circuit in the valve) 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 "CHECK ENGINE" malfunction indicator lamp (MIL) is activated by the ME-SFI control module. Also read out ETC diagnostic trouble code memory, fault code 6. |
