1 | Fault code | |
2 | Fault storage Activation "CHECK ENGINE" malfunction indicator lamp (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 | Voltage and current for activated charcoal canister shutoff valve |
5 | Fault setting conditions Limits Short circuit to ground Short circuit to +12 V Line interruption Test duration |
Voltage < 4 V Current > 4.2 A no voltage at the activated charcoal canister shutoff valve approx. 4 - 8 V at unloaded output of ME-SFI control module approx. 1 s |
6 | | The activation of the activated charcoal canister shutoff valve is tested for line interruption and short circuit (to ground or battery voltage). Short circuit to ground and line interruption is determined with a blocked output stage, whereas short circuit to battery voltage is determined with a conducting output stage. In the event of faults, the output stage is immediately no longer activated. |
