Diagnostic trouble code (DTC) CCM-0006 is stored if the control module registers that the signal from the evaporator temperature sensor is below 2% of the supply voltage (approximately 5 V).

Condition 

• The control module adopts a substitute value corresponding to approximately 0 °C.

Possible Source 

• Short-circuit to ground in the signal cable
• Defective evaporator temperature sensor.

Fault symptom[s] 

• No cooling from the air conditioning (A/C) system
• The air conditioning (A/C) compressor does not start, or runs sporadically
• Irregular cooling from the air conditioning (A/C) system.
