Following two successive driving cycles with faults | |
| 3 | Checking frequency | Continuous |
| 4 | Checked signal or status | Voltage and current for activated charcoal canister shutoff valve |
| 5 | Fault setting conditions | |
| Short circuit to ground | Voltage lower than 4 volts | |
| Short circuit to positive | Current higher than 4.2 A | |
| Open circuit in wiring | No voltage on activated charcoal filter shutoff valve, about 4 to 8 V on under no load output of ME-SFI [ME] control unit. | |
| 6 | Actuation of the activated charcoal canister shutoff valve is checked concerning a cable open-circuit and short-circuit (to ground or battery voltage). A short circuit to ground and a cable breakage will be recognized when the output stages are locked, while a short circuit to the battery voltage is recognized when the output stages are conducting. The output stage is immediately no longer activated when a fault arises. |
