Diagnosis By Symptom

The ATC system can perform an self-test, which can be activated by the DRBIII(R) scan tool to confirm that the air conditioning system is performing satisfactorily. This test provides a quick confirmation of heater - air conditioning system performance to the service technician. Refer to Body Diagnostic Procedures for the appropriate diagnostic information.
