Remote Climate Control Module Self-Test
- The remote climate control (RCC) module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A diagnostic tool must be used to retrieve these concerns.
- The RCC module self-test will detect concerns in the system control functions and will display hard DTCs. The vehicle interior temperature should be between 4°-38°C (40°-100°F) when carrying out the self-test. If the temperature is not within the specified range, false in-car temperature sensor DTCs will be displayed.
- The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated.
- To enter the self-test, press the OFF and floor buttons simultaneously and then press the AUTO button within 2 seconds. The display will show a dashed line in the center of the climate control display window of the integrated control panel (ICP).
NOTE:
Continuous memory DTCs can only be retrieved by the use of a diagnostic tool.
- The test may run as long as 30 seconds. Record all DTCs displayed. The self-test is completed when 888 appears in the center of the climate control display window of the ICP.
- If any DTCs appear during the self-test, refer to the REMOTE CLIMATE CONTROL (RCC) MODULE DIAGNOSTIC TROUBLE CODE (DTC) INDEX . Carry out the diagnostic procedure given under ACTION TO TAKE for each DTC given.
- If a condition exists but no DTCs appear during the self-test, refer to the Symptom Chart condition: The EATC System Is Inoperative, Intermittent or Incorrect Operation.
- To exit the self-test and retain all DTCs, press the "-" (cooler) side of the TEMP button. The RCC module will exit the self-test and retain all DTCs.
- To exit the self-test and clear all DTCs, press the front defrost button. All RCC module DTCs will be cleared.
- Always exit the self-test before powering the system down (system turned off).
- Continuous memory DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.
