Diagnostic trouble code (DTC) information
Condition
Diagnostic trouble code (DTC) CCM-0008 is stored if the control module registers that the signal from the sun sensor is above 98% of supply voltage (approximately 5 V).
The diagnostic trouble code (DTC) can only be diagnosed for the electronic climate control module (CCM) (ECC).
Substitute value
- The control module adopts a substitute value corresponding to approximately 20% (200 W/m2) of maximum solar heat.
Possible source
- Contact resistance, oxidation or loose connections in the connectors
- Open-circuit in the signal cable between the control module and the sun sensor
- Short-circuit to supply voltage in the signal cable between the control module and the sun sensor
- Short-circuit to supply voltage in the ground lead between the control module and the sun sensor
- Open-circuit in the ground lead between the control module and the sun sensor
- Defective sun sensor.
Fault symptom[s]
