Internal Fault. Permanent Fault

Internal fault. Permanent fault

Checking the passenger compartment temperature sensor
- Check that the ventilation holes for the passenger compartment temperature sensor in the climate control module panel are not blocked
- Remedy as necessary
- The climate control module is defective if the ventilation holes are blocked.

Note! The programmed values must be read off and noted before the climate control module is replaced.





Does the climate control module need to be replaced?

Yes - Reading off the programmed values

No - Verification

Yes - Programming the seat heater in the left seat

No - Information

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

Programming the seat heater in the left seat

Note! This function is used to program the heater for the left seat. In addition to activating the seat heater, the heat level must adapted for the type of upholstery. The maximum temperature for seat heaters with standard upholstery is 40 °C (104°F). The maximum temperature for seat heaters with leather upholstery is 43°C (109°F).




- Ignition on
- Read off and program the climate control module. Select the temperature level!

Caution! Programming must be carried out so that the high temperature setting is higher than the low temperature setting. The recommended difference between high and low levels is at least two degrees.Do not exceed the maximum level for the type of upholstery.

Read off the seat heater. Make a note of the value. If the programming is not correct, program in the correct version.









Do you wish to continue to program the next setting?

Yes - Programming the seat heater in the right seat

No - Information

Do you wish to continue to program the next setting?

Yes - Programming the disengagement time for rear windshield and door mirror heating

No - Information

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

Programming the disengagement time for rear windshield and door mirror heating

Note! The heating for the rear windshield and door mirrors is engaged using the button on the climate control module. This function is used to program the disengagement time for rear windshield and door mirror heating. The heating is either engaged as long as the function is activated using the button or disengages automatically after 12 minutes.




- Ignition on
- Read off and program the climate control module. Programmable data is: Disengagement after 12 minutes or No disengagement.
Read off the disengagement time. Make a note of the value. If the programming is not correct, program in the correct version.
Select Continue to exit programming.

Information

Caution! After programming a new climate control module, damper motor self-adjustment must be carried out. See the options below.

Select one of the following options:
1. Return to the start of programming or read off the programmed values
2. Exit programming and carry out damper motor self-adjustment (new climate control module)
3. Exit the programming.





Select alternative according to above.

2 - Self-adjustment of the shutter motor end position

3 - FAULT FOUND

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

Self-adjustment of the shutter motor end position





Self-adjustment of damper motor end positions

Self-adjustment of damper motor end positions. Electronic climate control (ECC), Manual climate control (MCC), Standard (STD)

Note! Self-adjustment must be carried out if the control module or damper motor is replaced or the damper motor or its linkage has been removed. The indication LED on the climate control module panel will flash during adjustment.

Hint: During self-adjustment the control module runs the damper motors to their limit positions. The control module then stores the value returned from the position sensor for the damper motor. The control module is then able to operate the motor betweenthe limit positions during normal operation.




- Start the engine (the generator charges)
- Activate self-adjustment. The self-adjustment takes thirty seconds.

Note! Self-adjustment can only be carried out once in the same ignition cycle. To run the self-adjustment again, switch off the ignition, wait 10 seconds and start the engine again.

The indication LED stops flashing when the self-adjustment is complete.

Verification




Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on
- Wait at least three minutes so that the control module has time to carry out its diagnostic
- Read off diagnostic trouble codes (DTCs).
The fault has been remedied if the status of the diagnostic trouble code (DTC) has changed to intermittent.





Has the status of the diagnostic trouble code (DTC) changed to intermittent?

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
