first stored in the junction box electronics and then relayed
to the DME.

Condition for fault identification
Test condition:
The fault is recognized when the output signal from the tank
fuel-level sensor is below a specified level.
Potential problem source(s):
- Defective wiring harness
- Tank fuel-level sensor on left (looking toward front) is
defective
Terminal condition: none
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V

- None
Time condition:
- None
Other conditions:
- Engine ON

Condition for fault memory entry
The diagnostic fault code is logged when the fault remains
present for longer than 3 min.

Action in service
- Read out and work through diagnostic fault codes in
instrument cluster and in junction box

Fault effect and breakdown warning
