Diagnostic Test

VERIFY THAT THE DIAGNOSTIC TROUBLE CODE (DTC) IS ACTIVE
1. Ignition on, engine not running.
2. Using the scan tool, read and record TIPM DTCs.
  NOTE:
  Record the Environmental Data for all DTCs before erasing. The Environmental Data can help in duplicating the conditions in which the DTC originally set.
3. Using the scan tool, erase TIPM DTCs.
4. Using the scan tool, actuate the Cabin Heater Relay 1 and allow the actuator to run for a least of two minutes.
5. Using the scan tool, read TIPM DTCs.
  Did this DTC reset?
  
  Yes
  - Go To 2
  No
