GENERAL INFORMATION
The battery, starting, and charging systems oper-
ate with one another, and therefore, must be thor-
oughly tested as a complete system. In order for the
vehicle to start and charge properly, it must have a
battery that will perform to specifications. The
starter motor, generator, wiring, and electronics also
must perform within specifications. Group 8A covers
starting (Fig. 1) and charging (Fig. 2) system diag-
nostic procedures. These procedures include the most
basic conventional methods to On-Board Diagnostics
(OBD) built into the Powertrain Control Module
(PCM). Use of an ammeter, volt/ohmmeter, battery
charger, carbon pile rheostat (load tester), and 12-
volt test lamp will be required.
All OBD sensing systems are monitored by the
PCM. The PCM will store in memory any detectable
failure in the monitored circuits. Refer to Using On-
Board Diagnostic System in this group for more in-
formation.

DOME/COURTESY LAMP SERVICE INFORMATION
XJ VEHICLES
Voltage is applied at all times via the dome lamp
fuse to each of the interior lamp bulbs. The interior
lamp bulbs illuminate when they are connected to
body ground via the switch:
²headlamp switch,
²glove box switch,
²door pillar switch, and
²liftgate switch (if the cargo lamp is ON.)
If equipped with Security Alarm Module, refer to
Group 8QÐVehicle Theft Security System.
YJ VEHICLES
The dome/cargo and courtesy lamps are controlled
via ON/OFF switches. The ON/OFF switches are in
the lamp ground circuits. Voltage via the dome/cour-
tesy lamp fuse is applied directly to the lamp bulbs.
When either door is opened, the door pillar switch
contacts close and provide a direct path to vehicle
body ground.
The cargo/cargo and courtesy lamps can also be
turned on via the interior lamp illumination rheo-
stat.
DOME/COURTESY LAMP TROUBLE DIAGNOSIS
ALL LAMPS INOPERATIVE
(1) Rotate the headlamp switch rheostat clockwise.
The lamps should light. If not OK, remove, inspect
and test the dome lamp fuse. Replace if bad.
(2) If the fuse is OK, repair the open circuit in the
wire harness to vehicle body ground.
ONE LAMP INOPERATIVE
(1) Measure the resistance across the bulb holder
terminals. The ohmmeter should indicate zero ohms.
If not, replace the bulb.
(2) Measure the voltage between the voltage side
of the bulb holder and vehicle body ground. The volt-
meter should indicate battery voltage. If not, repair
the open circuit in the wire harness to the splice.
LAMPS INOPERATIVE WITH ONE OR MORE
DOORS OPENED
(1) Remove the inoperative switch from the door
pillar and connect the switch wire directly to ground.
The lamp should light.
(2) If not, check for an open circuit in black
(ground) wire. Repair as necessary. If lamps still do
not light, replace the switch.
LIGHTED VANITY MIRROR
SERVICE INFORMATIONÐXJ VEHICLES
Both the driver and the front passenger sunvisor
can be equipped with a lighted vanity mirror. A
lamp located at each side of the vanity mirror. The
lamps are switched ON automatically when the mir-
ror cover is lifted (Fig. 1).
Voltage is applied directly to the vanity lamp bulbs
via the dome lamp fuse.
LIGHTED VANITY MIRROR TROUBLE DIAGNOSIS
VANITY LAMPS INOPERATIVE
(1) Remove, inspect and test the dome lamp fuse.
Replace if defective.
(2) Test the dome lamp operation. If OK, go to the
next step. If not OK, repair the open circuit in the
wire harness from the splice.

GENERAL
For information concerning wiring or connectors,
refer to Group 8W - Wiring Diagrams.
The mirror control switch contains two separate
switches, the operating switch and the selector
switch.
Each mirror has two reversible motors: one to ad-
just the mirror view up and down, the other to adjust
the mirror view right and left. The driver operates
three switches that control the polarity of the voltage
to the motors. The mirror select switch directs these
control voltages to either the right or left mirror.
The mirror select switch must be set to L or R to
direct current flow. If the mirror select switch is set
on R and the up-down switch is moved to the UP po-
sition, the voltage path is:
²through the U contact of switch 1
²to pin E
²to the up-down motor in the right mirror.
The ground path is:
²through pin D
²through the mirror select switch contacts
²to the U contacts of switch 3 and switch 2
²to pin F
²to ground.
The right motor runs and tilts the mirror up.
If the switch is pushed to the DOWN position, thesame motor receives voltage. Now the polarity is re-
versed, with pin E grounded. The motor runs in the
opposite direction.
The right mirror left-right motor operates in a sim-
ilar manner when the control switch is moved to the
L or R positions.
The left mirror works the same way as the right
mirror when mirror select switch is moved to L posi-
tion and control switch is operated.
DIAGNOSIS
For information concerning wiring or connectors,
refer to Group 8W - Wiring Diagrams.
²Open door. Dome lamps should light. If not, check
dome fuse.
Remove switch, unplug switch connector
²Measure resistance at mirror switch connector pin
F. Meter should read zero ohms, If not, repair open to
ground.
²Measure voltage at mirror switch connector pin G.
Meter should read battery voltage. If not, repair open
to dome fuse.
Install a jumper lead from pin E to pin F.
²Connect a jumper lead from pin G to: pin A; pin B;
pin C and then pin D. If the mirror moves, replace
switch. If not, repair open to motor and/or replace
motor.
