Park, Marker, Tail And License Lamps
Voltage is applied continuously to the tail relay pins 4 and 2.
The coil is energized when the daytime running lamps control module is active
in normal park or headlamp operation.
When the coils are energized current flows through the tail fuse and
then into the following lamps:
| • | The license plate lamps |
Turn Lamps
Voltage is applied from the turn fuse to cavity 7 of the hazard
switch. Current flows through the switch to cavity 5 where it continues
to cavity 2 of the turn/hazard flasher. Cavity 2 applies
voltage to the timing coil. At the same time cavity 2 applies
voltage to the contact that closes according to the timing of the turn/hazard
flasher. When the contacts are closed it applies current to the turn
signal/headlamp switch cavity 2. If no direction is set by the
turn signal switch an open occurs between cavities 1,2 and 3 of
the switch. Current flows only to the left or right set of lamps, depending
which way the turn signal switch is turned to.
The following lamps are turned on pertaining to the side the switch
is activated to:
| • | The left or right front turnlamp |
| • | The left or right rear turnlamp |
| • | The left or right indicator lamp |
Hazard Lamps
Voltage is applied from Hazard fuse to cavity 6 of the hazard
switch. When turned to the on position current flows through the switch to
cavity 5 where it continues to cavity 2 of the turn/hazard
flasher. Cavity 2 applies voltage to the timing coil. At the same
time cavity 2 applies voltage to the contact that closes according
to the timing of the turn/hazard flasher. When the contacts are closed
it applies current to the hazard switch cavity 4. Current flows
from cavity 4 through the closed contacts at cavity 1 and
2.
The following lamps are turned on when cavities 1 and 2 are charged:
| • | The left and right front turnlamp |
| • | The left and right rear turnlamp |
| • | The left and right indicator lamp |
Stoplamps and Center High Mount Stoplamp
Voltage is applied continuously from the stop fuse to the stoplamp switch.
Voltage is applied from the stoplamp switch to junction block 1 C6
cavity 6 when the brake pedal is pressed. Voltage flows to junction
block 1 C5 cavity 7, continuing to SP450. At the same
time that happens current flows through junction block 1 C3
cavity 1 to junction block 3 C3 cavity 2.
SP450 applies voltage to the following lamps:
| • | The left and right stoplamps |
| • | The center high mounted stoplamp (CHMSL) |
Junction block 3 C3 cavity 2 applies voltage to the following
brake signal receivers:
| • | Shift Lock Control Module (w/ automatic transaxle) |
| • | Brake Pressure Modulator Valve (w/ ABS) |
| • | Powertrain Control Module |
