Faulty Signal
Faulty signal
Status check
- Start the engine. Read off the fuel consumption value in the driver information module (DIM).
Check that the fuel consumption value is within its permitted range. The value is approximately 1-2 liters when the engine is idling.
Is the fuel consumption value outside its permitted range?
Yes - Checking the component and wiring
No - Checking the component and wiring
-------------------------------------------------
Checking the component and wiring
Check the signal cable between the engine control module (ECM) and combined instrument panel terminal #B5 (#5). Check for a short-circuit to ground. Check for a short-circuit to supply voltage. Check for an open-circuit.
Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reinstall the connectors, components etc.
- Start the engine. Read off the fuel consumption value in the driver information module (DIM).
Check that the fuel consumption value is within its permitted range. The value is approximately 1-2 liters when the engine is idling.
Is the fuel consumption value within the permitted range?
Yes - VERIFIED
No - VERIFICATION FAILED

Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit fault-tracing
No - Attempt New Test
------------------------
Attempt New Test - Checking the component and wiring
-------------------------------------------------
Checking the component and wiring
Check the signal cable between the engine control module (ECM) and the combined instrument panel terminal #B5 (#5). Check for an intermittent short-circuit to ground. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.
Remedy as necessary.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
