Signal Too High
Signal too high
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 for a short-circuit
-------------------------------------------------
Checking for a short-circuit
If the car is equipped with a 16-pin connector
Check the cable between driver door module (DDM) terminal #18A and power door mirror connector terminal #3. Check for an open-circuit.
Check the cable between driver door module (DDM) terminal #14A and power door mirror connector terminal #2. Check for a short-circuit to supply voltage. Check for an open-circuit.
Replace the cable if a fault is found.
Try a new outside temperature sensor if no fault was found.

-------------------------------------------------
Intermittent fault
Check the control module and power door mirror connectors. Check for contact resistance, oxidation and loose connections.
If the car is equipped with a 16-pin connector
Check the cable between driver door module (DDM) terminal #14A and power door mirror terminal #2. Check the cable between control module terminal #18A and power door mirror terminal #3. Check these cables for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.
Try a new outside temperature sensor if no fault was found.

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reconnect the components, connectors etc.
- Ignition on.
Check the outside temperature.
Is the temperature within its permitted range?
Yes - VERIFIED

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

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).
