Turn Signals: Description and Operation

TURN SIGNAL/CORNERING LAMPS

The HZDT/SIG fuse in the fuse block - left underhood supplies battery positive voltage to the turn signal/hazard flasher module and have ground at G202. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. The T/SIG fuse in the fuse block - left underhood supplies battery positive voltage to the turn signal/multifunction switch. When the turn signal/multifunction switch is placed in either the left or right position, current flow is from the turn signal/multifunction switch assembly to the turn signal/hazard flasher module. The turn signal/hazard flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators. The left turn signals have ground at G106, G400 and at G402. The right turn signals have ground at G105 and G400. The turn signal/multifunction switch supplies battery positive voltage to the cornering lamps, the left cornering lamp has ground at G106 and the right cornering lamp has ground at G105.
