Where are my Front Control Module (FCM) and ABS Module located? ('05 Jeep GC Ltd 4.7)
The FCM is mounted to the fuse box under the hood.
The ABS module is mounted to the ABS hydraulic control unit under the hood. If you find the large aluminum block where the brake lines all go in you will also see a large electrical connector, this is the module connector.
Any idea why this would happen only while the lights are on?
