Turn Signal, Hazard Lamps Circuit

Both the TRN-BU and the STOP-HAZ fuses in the IP junction block supplies battery positive voltage to the flasher module, which is part of the hazard switch assembly. When the turn signal switch is placed in either the left or right position, current flow is from the flasher module's left or right hand output to the turn signal switch assembly. The flasher module then sends an on-off (flashing) voltage to either the left turn signals and their instrument cluster indicators, or the right turn signals and their instrument cluster indicators. The front turn signals are grounded at G102. The rear turn signals are grounded at G304.

When the hazard switch is pressed, the hazard switch contacts close and the flasher module is connected to the turn signal lamps. The turn signal/hazard flasher supplies battery positive voltage in an on-off flashing pattern to all the turn signal lamps. All the turn signal lamps and both turn indicators illuminate in the same flashing pattern.
