FAN 1 RELAY CONTROL CIRCUIT
Output Driver Modules (ODM) are used by PCM to turn on
current-driven devices needed to control various engine and transaxle
functions. Each ODM can control up to 7 outputs, including fan 1
relay, by supplying ground to device PCM is commanding on. ODMs can
diagnose each circuit individually.
You likely won't notice any drivability problems.
- An improper voltage level has been detected on fan 1 relay
- Check voltage at fan connection. Should be battery votage.
- Check fan 1 relay ignition feed fuse.
- Replace fan 1 relay.
