Yes → Go To 5
→ Repair the open in the (C24) Low Speed Radiator Fan Relay
No
5 Turn the ignition off.
Remove the Low Speed Radiator Fan Relay from the PDC.
Disconnect the PCM harness connector.
Measure the resistance of the (C24) Low Speed Radiator Fan Relay Control circuit in
the PDC to ground.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the (C24) Low Speed Radiator Fan
→ Go To 6
No
6 NOTE: Before continuing, check the PCM harness connector terminals for
