The Remote Climate Control (RCC) module is capable of displaying both self-test faults and intermittent (run time) faults on the Integrated Control Panel (ICP). To obtain these codes, perform the following EATC on-board diagnostics test:

. On-board diagnostics should be run in ambient temperatures between 50 and 90 degrees F. Record all Diagnostic Trouble Codes (DTCs) displayed during diagnostic test mode.

. Turn ignition switch to RUN position.

. Push both OFF and FLOOR buttons simultaneously; then, press AUTO within two seconds.

. The test may run as long as 30 seconds, while the display will show a dashed line in the center of the display window.

. After about 20 seconds, a DTC will appear in the display. The self-test is completed when 888 appears in the center of the climate control display window of the ICP.

. To exit the self-test and retain all intermittent DTCs, press the "-" (cooler) side of the TEMP button. The RCC module will exit the self-test and retain all intermittent DTCs.

. Always exit the self-test, before powering the system down (system turned off).

. Refer to a DTC Index for additional help. Here are several common self-test faults:

024--A/C Electronic Blend Door Actuator Failure
030--In-Car Temperature Sensor Short
031--In-Car Temperature Sensor Open
040--Ambient Temperature Sensor Short
041--Ambient Temperature Sensor Open
050--Sunload Sensor Short

. Some heating and air conditioning control problems are solved just by running the self-test.


NOTE: Intermittent (run time) trouble codes will be deleted after 80 ignition cycles.
