Faulty Signal

Checking the passenger compartment temperature sensor




- Ignition on
- Check that the temperature corresponds to the ambient temperature.
Alternately blow hot and cold air onto the sensor. Check that the value displayed on the sensor changes.
Shine a light through the grille over the passenger compartment temperature sensor. Check for anything that could obstruct the airflow through the pipe.
Take care not to damage the sensor. The sensor is located just inside the grille.
Remedy as necessary.

Other information:
- To access or replace the climate control system, see Climate control module (CCM), replacing Service and Repair.









Is the sensor value correct?

Yes - Fault-tracing information

No - Replacing the component

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

Replacing the component
The fault is probably a defective passenger compartment temperature sensor. This type of fault means that the entire control module must be replaced. The passenger compartment temperature sensor cannot be replaced separately.
Replace the control module. See Climate control module (CCM), replacing Service and Repair.

Self-adjustment




Limit positions for damper motor self-adjustment

Choice of climate control
1. Electronic climate control (ECC)
2. Manual climate control (MCC) / Standard (STD).

Select the type of climate control.

2 - Limit positions for damper motor self-adjustment

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

Limit positions for damper motor self-adjustment

Hint: After replacing the control module or shutter motors, and when a shutter motor or link has been removed, carry out self adjustment to define the shutter motor limit positions.




- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Activate the self-adjustment. Wait at least 30 seconds.
Ignition off for at least 1 minute.
Start the engine.

Verification

Hint: After the repair it is necessary to check that the fault has been rectified.








- Ignition off.
- Connect the connectors, install the components, etc.
- Ignition on.
Read the interior temperature and vary the temperature with the interior temperature sensor to see if the value changes. Check that the value is normal using a thermometer.





Is the value OK?

Yes - VERIFIED

No - VERIFICATION FAILED

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

VERIFIED - Fault Found

VERIFICATION FAILED - Fault-tracing information

Fault-tracing information




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 - FAULT-TRACING FAILED

No - Attempt New Test

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

FAULT-TRACING FAILED - No Fault Found

Attempt New Test - Checking the passenger compartment temperature sensor

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

Fault-tracing information
The fault has probably occurred as a result of a defective power circuit in the climate control system. If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the control module or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. If the fault recurs, replace the control module.

Information

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).
