the headlamp switch, the headlamp delay module
powers the headlamps for approximately 45 seconds.
When the ignition switch is in the RUN position,
circuit A21 powers circuit F87 through fuse 17 in the
fuse block. Circuit F87 supplies the IGNITION ON/
OFF signal to the headlamp delay module. Circuit Z1
provides ground for the module.
When the headlamp delay module activates, it con-
nects circuit X4 from fuse 11 in the fuse block to cir-
cuit F34. Circuit F34 powers the headlamps through
the headlamp dimmer switch circuit L3.

MALFUNCTION INDICATOR (CHECK ENGINE)
LAMP
The Powertrain Control Module (PCM) provides
ground for the malfunction indicator (Check Engine)
lamp on circuit G3. Circuit G3 connects to cavity 32
of the PCM. Circuit G5 connects to the instrument
cluster and supplies battery voltage for the malfunc-
tion indicator lamp. When illuminated, the malfunc-
tion indicator lamp displays the message CHECK
ENGINE.
For information regarding diagnostic trouble code
access using the malfunction indicator lamp, refer to
Group 14, Fuel Systems.
UP-SHIFT LAMP
On vehicles equipped with a manual transmission,
the Powertrain Control Module (PCM) provides
ground for the Up-Shift lamp on circuit K54. Circuit
G5 provides battery voltage for the lamp.
ABS WARNING LAMP
Circuit G5 provides power for the ABS warning
lamp at the instrument cluster. Ground for the ABS
warning lamp is provided by either the ABS control
module or by the ABS power relay when the relay is
not energized. The ABS control module illuminates
the lamp by providing ground on circuit G19.
Circuit G19 splices to connect to circuit B15
through a diode. When the ABS power relay is not
energized, it connects circuit B15 to circuit Z12. The
ground path for the warning lamp is provided
through the diode to circuit B15, through the ABS
power relay to ground on circuit Z12.
The diode between circuit G19 and B15 prevents
voltage from flowing to the ABS control module when
the ABS power relay switches to supply power on cir-
cuit B15.
BRAKE WARNING LAMP
Circuit G5 provides battery voltage for the brake
warning lamp. Circuit G11 can provide ground for
the lamp in 3 ways. The first ground path is through
the ignition switch when the key is in the START po-
sition.
The second ground path for the brake warning
lamp on circuit G11 is through the case grounded
brake warning switch. When the switch closes it pro-
vides a ground.
The third ground path on circuit G11 is through
the case grounded park brake switch. When the
switch closes it provides ground.
HIGH BEAM INDICATOR LAMP
Circuit G34 supplies power for the high-beam indi-
cator lamp when the operator either flashes the opti-
cal horn (high beams) or selects high beam operation.
Circuit Z1 provides the ground path for the lamp.
Circuit L3 from the headlamp switch powers the
high beam circuits of the headlamps. On vehicles not
equipped with Daytime Running Lamps (DRL), cir-
cuit G34 double crimps to circuit L3 at the bulkhead
connector.
On vehicles equipped with DRL, circuit L3 splices
to the DRL module. The DRL module powers circuit
G34.
TURN SIGNAL INDICATOR LAMPS
Circuit L61 supplies battery voltage to the left turn
signal indicator lamp. The right turn signal indicator
lamp receives battery voltage from circuit L60. The
turn signal/hazard flasher switch powers circuits L60
and L61. Circuit Z1 provides ground for the lamps.
HELPFUL INFORMATION
²If the warning lamps, gauges and indicator lamps
don't operate, check fuse 4 in the PDC and fuse 9 in
the fuse block.
²If the illumination lamps don't operate, check fuse
10 in the fuse block.

HEADLAMPS
The headlamp switch has three positions: ON,
PARK (parking lamps) and OFF. Two circuits, L2 and
L20, connect the headlamp switch to the headlamp
dimmer/optical horn switch. The dimmer switch feeds
the low and high beams of the headlamps.
HEADLAMP SWITCH IN OFF OR PARKING
LAMP POSITION
Circuit A3 from fuse 7 in the Power Distribution
Center (PDC) supplies battery voltage to the head-
lamp switch. The headlamp switch has an internal
circuit breaker that connects circuit A3 to circuit
L20. The switch connects circuit A3 to circuit L2
when the headlamps are ON.
Circuit L20 connects to the dimmer switch. Circuit
L20 powers the high beams of the head lamps on cir-
cuit L3 when the operator flashes the headlamps
with the turn signal stalk.
HEADLAMP SWITCH IN ON POSITION
When the headlamp switch is in the ON position,
the A3 circuit from the PDC connects to circuit L2.
Circuit L2 connects to circuit L4 through the dimmer
switch. Circuit L4 powers the low beam of the head-
lamps.
When the operator selects high beam operation
with the turn signal stalk, the dimmer switch con-
nects circuit L20 to circuit L3. Circuit L3 supplies
battery voltage to the high beams.
HEADLAMP GROUND
Although circuit Z1 provides ground for both the
right and left headlamps, it has different termination
points for each. For the right headlamp, the Z1 cir-
cuit terminates at the radiator right support. For the
left headlamp, the Z1 circuit terminates at the left
radiator support.
HELPFUL INFORMATION
²Check fuse 7 in the PDC.
²The headlamp switch has an internal circuit
breaker.
²For the left front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the left radiator support.²For the right front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the right radiator support.
PARKING LAMPS
Circuit A6 from fuse 3 in the Power Distribution
Center (PDC) connects to the fuse block bus bar that
powers circuit F33. Fuse 8 in the fuse block protects
circuit F33. Circuit F33 connects to the headlamp
switch.
The headlamp switch has three positions: ON,
PARK (parking lamps) and OFF, plus a dimmer
switch. When the headlamp switch is in the PARK or
ON position, the switch connects circuit F33 to cir-
cuit L7. From the headlamp switch, circuit L7
branches to power the front parking lamps, rear tail
lamps, and side marker lamps. Circuit L7 also pow-
ers the park lamp relay, if equipped with fog lamps.
GROUND CIRCUIT
²For the left front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the left radiator support.
²For the right front parking lamp, turn signal, side
marker lamp, headlamp, and fog lamp, circuit Z1 ter-
minates at the right radiator support.
HELPFUL INFORMATION
²Check fuse 3 in the PDC.
²Check fuse 8 in the fuse block.
²Circuit L7 also feeds the radio, if equipped.
FOG LAMPS
The fog lamps are controlled by the fog lamp
switch and two relays. The fog lamps operate only
when the headlamp switch is in the ON position, and
the operator has selected low-beam operation. When
the headlamps are in high-beam operation, the fog
lamps will not operate.
When the headlamps or parking lamps are ON, cir-
cuit L7 from the headlamp switch supplies battery
voltage to the coil side of the park lamp relay. When
the operator presses the fog lamp switch, it provides
ground for the coil side of the park lamp relay. This
energizes the relay.
