Signal missing

Checking for permanent or intermittent faults




- Ignition on.
Check the outside temperature.

Note! The outside temperature sensor is always located in the right door mirror, irrespective of whether the car is left or right-hand drive.





Is the temperature within its permitted range?

Yes - Intermittent fault

No - Checking the connectors

-------------------------------------------------

Checking the connectors








- Ignition off
- Check the power door mirror connector for contact resistance and oxidation. Remedy. Check for damage carefully
- Reinstall the components, reconnect the connectors etc.
- Ignition on.
Check the outside temperature.

Note! The outside temperature sensor is always located in the right door mirror, irrespective of whether the car is left or right-hand drive.

Is the temperature within its permitted range?

Yes - Verification

No - Checking for a short-circuit

-------------------------------------------------

Checking for a short-circuit

If the car is equipped with a 10-pin connector
Check the cable between door control module terminal #14A and power door mirror connector terminal #1. Check for a short-circuit to ground.

If the car is equipped with a 16-pin connector
Check the cable between door control module terminal #14A and power door mirror connector terminal #2. Check for a short-circuit to ground.
Replace the cable if a fault is found.
Try a new outside temperature sensor if no fault was found.

Intermittent fault

If the car is equipped with a 10-pin connector
Check the cable between control module terminal #14A and power door mirror terminal #1. Check for an intermittent short-circuit to ground.

If the car is equipped with a 16-pin connector
Check the cable between control module terminal #14A and power door mirror terminal #2. Check for an intermittent short-circuit to ground.
Replace the outside temperature sensor if no fault is found.

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.

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).
