HVAC Module - Dual Automatic Temperature Control (DATC) - Retrieve Continuous DTCs

HVAC MODULE - DUAL AUTOMATIC TEMPERATURE CONTROL (DATC) - RETRIEVE CONTINUOUS DTCS

The HVAC module - DATC will retrieve only continuous (intermittent) DTCs when carrying out this procedure.

- Retrieval of continuous DTCs can be initiated after cycling the ignition switch from OFF to ON. Normal operation of the climate control system stops when retrieving continuous DTCs.
- To retrieve continuous DTCs, press the OFF and DEFROST buttons simultaneously and release, then press the RECIRC button within 2 seconds. The display will show a flashing "----" for a maximum of 20 seconds, after which "8888" will be displayed if there are no continuous DTCs present. If DTCs are present, the HVAC module - DATC will display the continuous DTCs present. Record all DTCs displayed.
- If any DTCs appear, carry out the diagnostic procedure. Refer to the HVAC Module - Dual Automatic Temperature Control (DATC) DTC Chart and follow the ACTION for each DTC given. Diagnostic Trouble Code Tests and Associated Procedures
- If a condition exists but no DTCs appear, GO to Symptom Chart - Climate Control System condition: The Dual Automatic Temperature Control (DATC) System is Inoperative, Intermittent or Incorrect Operation. Symptom Chart - Climate Control System
