Defect Code 7

*D* Defect code memory: 7 Temperature input

Explanation:
This defect code is stored when a defect is detected by the on-board computer (BC) in the area of the temperature sensor.

Possible symptoms:
Incorrect temperature indication; temperature warning gong at incorrect temperature signal; problems in operation of independent heating/ventilation.

Possible cause:
Wire from BC to temperature sensor defective.

Troubleshooting:
Check wire and repair if necessary (from black BC connector Pin 12 to temperature sensor connector Pin 1 and further to ground).

If wire OK., renew temperature sensor.

If the temperature sensor is replaced, the correct temperature is not indicated before a certain adjustment time of the temperature sensor.
