AZC Module DTCs

Active DTCs are those which currently exist in the system. The condition causing the fault must be repaired in order to clear this type of DTC.
Active DTCs become stored DTCs when the condition that caused the active DTC no longer exists.
Stored DTCs will be erased after 72 key cycles or by clearing them with the DRBIII®.
Diagnostics for symptoms pertaining to A/C compressor operation can be found in the Heating & A/C category of thisarticle and in the Powertrain Diagnostic Procedures article.
Refer to the Service procedures for additional AZC system diagnosis and testing information.
