FAULT CODE

2000 Dodge Dakota • 6 cylinder Automatic • 94,000 miles

2000 dodge dakota. Diagnostic check returned "1491 radiator fan relay circuit". I think that fan also works with the ac system and the ac works fine. Someone said maybe PCM is problem. Signal goes through same relay for cooing system? Help before I buy a PCM. Would reflashing maybe fix it.

The cooling fan relay code has nothing to do with the PCM being bad. You need to test all the inputs and outputs to the relay.
