ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for additional fault codes related to the cooling system or control circuits that may provide further insights.OBD-II Scanner
Test Cooling Fan 1 FunctionalityUse a diagnostic tool to test the operation of cooling fan 1. Verify if the fan is receiving the correct signals from the control module and if it turns off when expected.Diagnostic Tool
Inspect Cooling Fan 1 for StickingVisually inspect cooling fan 1 for mechanical issues such as debris, dirt, or damage that may cause the fan to remain on. Ensure that it is not physically stuck in the “on” position.Flashlight
Check Control Circuit for FaultsInspect the control circuit for fan 1, including the relay and wiring, for any signs of malfunction. Look for stuck relays, broken wiring, or improper signals from the control module.Multimeter, Relay Tester
