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 scan 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 diagnostic trouble codes (DTCs) in addition to intermittent diagnostic trouble codes for concerns that occur during system operation.
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 two seconds.
The display will show a dashed line in the center of the climate control display window of the integrated control panel (ICP).
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.
