Fault-Tracing Information

Fault tracing

Checking the status




- Ignition on
Check if the malfunction is permanent or intermittent by reading off the signal from the fuel level sensor (via central electronic module (CEM)) and check that it is reasonable, that it moves when the vehicle is rocked lightly and that it then stabilizes at a reasonable level.
Incorrect signal indicates that the malfunction is permanent. If the signal is reasonable, this indicates that the malfunction is intermittent.

Hint: Completely full tank may mean that the level change when rocking the vehicle is not clear enough.









Continue - Checking connector

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on
Read off the signal from the fuel level sensor (via central electronic module (CEM)).
Check that the signal is reasonable, that it moves when the vehicle is rocked lightly and that it then stabilizes at a reasonable level.
Reasonable signal indicates that the malfunction has been remedied.

Hint: Completely full tank may mean that the level change when rocking the vehicle is not clear enough.









Is the signal reasonable?
