Preliminary Checks

  1. Perform QUICK TEST  to retrieve any cooling fan related DTCs. During QUICK TEST, 3 types of DTCs are retrieved: KOEO, KOER and Continuous Memory DTCs.
  2. If any cooling fan related DTCs are present, identify DTC and go to appropriate step. See CONSTANT CONTROL RELAY MODULE RELATED DTCS  table. If no DTCs are present, connect scan tool to Data Link Connector (DLC).
  3. Turn ignition on. Access OUTPUT TEST MODE on scan tool. Command cooling fan on and check fan operation. On models with 2 fan speeds, check both fan speeds. On all models, if fan does not operate properly, perform appropriate test.
