²Fuel pump fuse (20 Amp)
²Interior lamps fuse (10 Amp)
(6) If there is any reading with fuses removed
there is a current draw or short circuit in the wiring.
Refer to Group 8W, Wiring Diagrams. If OK go to
Step 7.
(7) Install interior lamp fuse. After installing fuse,
the current can reach 250 milliamperes. After time-out the reading should not exceed 8 milliamperes. If
NOT OK go to Step 8. If OK go to Step 9.
²Ignition key lamp system
²Radio
²Remote keyless entry module, if equipped
(8) Disconnect radio and ignition switch key lamp
one component at time, to see if any component is at
fault. If the high reading is not eliminated there is a
short circuit in the wiring. Refer to Group 8W, Wir-
ing Diagrams.
CAUTION: Always disconnect the meter before
opening a door.
(9) Remove interior lamps fuse and install the fuel
pump fuse. The reading should be between 1-3 milli-
amperes. If reading is higher than 3 milliamperes:
(a) Disconnect Powertrain Control Module.
(b) If reading drops to zero, replace Powertrain
Control Module.
(c) If reading remains the same there is a cur-
rent draw or short circuit in the A14 circuit. Refer
to Group 8W, Wiring Diagrams.
BATTERY DIAGNOSIS AND TESTING
STEPS POSSIBLE CAUSE CORRECTION
VISUAL INSPECTION
Check for possible damage to
battery and clean battery.(1) Loose battery post, Cracked
battery cover or case, Leaks or Any
other physical
(2) Battery OK.(1) Replace Battery
(2) Check state of charge. Refer to
Test Indicator.
TEST INDICATOR
Check Charge Eye Color(1) GREEN
(2) BLACK
(3) CLEAR(1) Battery is charged. Perform
Battery 0pen Circuit Voltage Test
(2) Perform Battery Charging
procedure.
(3) Replace Battery.
BATTERY OPEN CIRCUIT
VOLTAGE TEST(1) Battery is above 12.40 Volts
(2) Battery is below 12.40 Volts.(1) Perform the Battery Load Test.
(2) Perform Battery Charging
procedure.
BATTERY CHARGING (1) Battery accepted Charge.
(2) Battery will not accept charge(1) Ensure that the indicator eye is
GREEN and perform Battery 0pen
Circuit Voltage Test
(2) Perform Charging a Completely
Discharged Battery.
BATTERY LOAD TEST (1) Acceptable minimum voltage.
(2) Unacceptable minimum voltage(1) Battery is OK to put in use,
perform Battery Ignition Off Draw
Test.
(2) Replace Battery and perform
Battery Ignition Off Draw Test.
CHARGING A COMPLETELY
DISCHARGED BATTERY(1) Battery accepted charge.
(2) Battery will not accept charge.(1) Ensure that the indicator eye is
GREEN and perform Battery 0pen
Circuit Voltage Test.
(2) Replace Battery.
IGNITION OFF DRAW TEST (1) IOD is 5-25 Milliamperes.
(2) IOD Exceeds 25 Milliamperes.(1) Vehicle is normal.
(2) Eliminate excess IOD draw.

GENERAL INFORMATION
HEADLAMP LEVELING MOTOR
This vehicle is equipped with a remote headlamp
leveling system. This system allows the driver to
adjust the vertical headlamp aim from the interior ofthe vehicle to compensate for passenger or cargo
load. A headlamp leveling switch is located in the
instrument panel and controls the headlamp leveling
motor and leveling cable found mounted to the upper
radiator crossmember behind the headlamp assem-
bly.

GENERAL INFORMATION
INTRODUCTION
The key fob transmitter has three buttons to actu-
ate and program the Remote Keyless Entry (RKE)
system (Fig. 1).
²UNLOCK: Actuating the UNLOCK button once
will unlock the driver door and activate the illumi-
nated entry system. Actuating the UNLOCK button
twice within five seconds will unlock all doors.
²LOCK: Actuating the LOCK button locks all
doors and sounds horn (chirp). The chirp verifies the
door lock operation.
²PANIC: Actuating the PANIC button sounds the
horns and alternately flashes the headlamps and
parking lamps. The panic alarm will remain on for
one minute, until the PANIC button is actuated
again or the ignition is switched to the RUN position.
²The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code (VAC)
in memory even after vehicle power has been inter-
rupted.
DESCRIPTION AND OPERATION
VEHICLE ACCESS CODE (VAC) PROGRAMMING
The system allows locking and unlocking of vehicle
door(s) by remote control using a hand held radio fre-
quency transmitter. The ignition switch must be OFF
before the panic function can be activated with the
transmitter.
The receiver may receive VAC signals from two
transmitters. Each transmitter has its own VehicleAccess Code and the code is programmed and stored
into receiver memory. If the transmitter is replaced
or a second transmitter is added, the codes of both
units have to be reprogrammed into the receiver
memory. If a receiver module is replaced, both the
transmitter codes must be stored in the new receiver
memory.
OPERATION
The transmitter has three buttons for operation
(Fig. 1). They are LOCK, UNLOCK and PANIC.
The receiver is capable of retaining all Vehicle
Access Codes (VAC) even when power is removed.
Each remote keyless entry module (RKE) must
have at least one and no more than two transmitters.
