Electronic Automatic Temperature Control Module - Retrieve Continuous DTCs

The EATC module 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. All vacuum fluorescent segments will be displayed if there are no continuous DTCs present. Continuous DTCs are indicated by the presence of the c Celsius symbol (°C) on the EATC module display. Record all DTCs displayed.
• If any DTCs appear, carry out the diagnostic procedure. Refer to the Electronic Automatic Temperature Control (EATC) Module Diagnostic Trouble Code (DTC) Index  and follow the ACTION for each DTC given.
• If a condition exists but no DTCs appear, GO to SYMPTOM CHART  Condition: The EATC System Is Inoperative, Intermittent or Incorrect Operation.
• To exit and retain  all continuous DTCs, press any button except  DEFROST. The EATC module will exit the retrieved continuous DTCs mode and retain all continuous DTCs.
• To exit and clear  all continuous DTCs, press the DEFROST button. The EATC module will exit the retrieve continuous DTCs mode and all continuous DTCs will be cleared.
• Always exit the procedure before powering the system down (system turned OFF). Once the procedure is exited, the ignition switch must remain ON for at least 30 seconds to allow the door actuators to automatically recalibrate.
• Continuous DTCs will be deleted after 80 ignition switch ON cycles after the intermittent fault occurs.
