Faults (lead interruption or short-circuit of control, short-circuit in the valve) are detected by the ETC control module; the ME-SFI control module is then informed of these via the CAN data bus. Fault storage and activation of the malfunction indicator lamp are carried out by the ME-SFI control module. Additionally read out ETC diagnostic trouble code memory. |
