Exterior Lights Circuit Description

Battery positive voltage (B+) is supplied at all times to the turn/hazard flasher module from the rear fuse block TSIG/HAZ Fuse. The turn/hazard flasher module is permanently ground. Battery positive voltage (B+) is supplied with the ignition switch in the ON or START position to the turn signal switch in the steering column from the rear fuse block IGN 1 Fuse.

When the turn signal switch is placed in the position to indicate a LH turn, battery positive voltage (B+) is input to the turn/hazard flasher module Left Turn Input. In response to this input, the turn/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to the LH turn lamps. The LH turn lamps are permanently grounded, so the LH turn lamps light when they have power and ground and turn off while power is removed.

When the turn signal switch is placed in the position to indicate a RH turn, battery positive voltage (B+) is input to the turn/hazard flasher module Right Turn Input. In response to this input, the turn/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to the RH turn lamps. The RH turn lamps are permanently grounded, so the RH turn lamps light when they have power and ground and turn off while power is removed.
