Turn Signal Lamp: Description and Operation

TURN SIGNAL LAMPS

Ignition positive voltage from the TRN SIG fuse in the console fuse block is supplied to the turn signal switch. when the turn signal lever is placed in the turn left or turn right position, voltage is applied to the turn signal lamp flasher assembly in the console fuse block. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. When the turn signal switch is placed in either the left or right position, current flow is from the flasher module's output to the turn signal switch assembly. The flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. For the hazard lamps voltage is applied from the HZDL fuse in the console fuse block to the hazard flasher. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators. The hazard and turn signal lamp flasher assembly is grounded at G200. The front turn signals are grounded at G100 and G101 and the rear turn signals are grounded at G401 and G402.
