DIAGNOSIS AND TESTING (Continued)
cluster wire harness connector B and the washer
fluid level sensor wire harness connector. There
should be continuity. If OK, replace the faulty bulb.
If not OK, repair the open low washer fluid level
sense circuit as required.
SECURITY LAMP
The diagnosis found here addresses an inoperative
security lamp condition. If the problem being diag-
nosed is an inaccurate security lamp, refer to Vehi-
cle Theft Security System in the Diagnosis and
Testing section of Group 8Q - Vehicle Theft/Security
Systems for diagnosis. For complete circuit diagrams,
refer to Instrument Cluster in the Contents of
Group 8W - Wiring Diagrams.
(1) Check the fused B(+) fuse in the junction block.
If OK, go to Step 2. If not OK, repair the shorted cir-
cuit or component as required and replace the faulty
fuse.
(2) Check for battery voltage at the fused B(+) fuse
in the junction block. If OK, go to Step 3. If not OK,
repair the open fused B(+) circuit to the battery as
required.
(3) Disconnect and isolate the battery negative
cable. Remove the Central Timer Module (CTM). Dis-
connect the CTM wire harness connectors. Connect
the battery negative cable. Install a jumper wire
between the VTSS indicator driver circuit cavity of
the 18-way CTM wire harness connector and a good
ground. The security lamp should light. If OK, use a
DRB scan tool and the proper Diagnostic Procedures
manual to diagnose the Vehicle Theft Security Sys-
tem (VTSS) and the CTM. If not OK, go to Step 4.
(4) Disconnect and isolate the battery negative
cable. Remove the instrument cluster. Check for con-
tinuity between the fused B(+) circuit cavity of the
instrument cluster wire harness connector A and the
fused B(+) fuse in the junction block. There should be
continuity. If OK, go to Step 5. If not OK, repair the
open fused B(+) circuit to the fuse in the junction
block as required.
(5) Check for continuity between the VTSS indica-
tor driver circuit cavities of the instrument cluster
wire harness connector A and the 18-way CTM wire
harness connector. There should be continuity. If OK,
refer to Instrument Cluster - Self-Diagnostic Test
in the Diagnosis and Testing section of this group for
further diagnosis of the security lamp and the instru-
ment cluster circuitry. If not OK, repair the open
VTSS indicator driver circuit as required.
INSTRUMENT PANEL SYSTEMS
TURN SIGNAL INDICATOR LAMP
The diagnosis found here addresses an inoperative
turn signal indicator lamp condition. For any other
turn signal problem, refer to Turn Signal and Haz-
ard Warning Systems in the Diagnosis and Testing
section of Group 8J - Turn Signal and Hazard Warn-
ing Systems for further diagnosis. If no turn signal or
hazard warning system problem is found, the follow-
ing procedure will help locate a short or open in the
indicator lamp circuit. For complete circuit descrip-
tions, refer to Instrument Cluster in the Contents
of Group 8W - Wiring Diagrams.
(1) Disconnect and isolate the battery negative
cable. Remove the instrument cluster.
(2) Connect the battery negative cable. Activate
the hazard warning system by moving the hazard
warning switch button to the On position. Check for
battery voltage at the inoperative (right or left) turn
signal circuit cavity of the instrument cluster wire
harness connector B. There should be a switching (on
and off) battery voltage signal. If OK, replace the
faulty (right or left) turn signal indicator lamp bulb.
If not OK, repair the open (right or left) turn signal
circuit to the turn signal/hazard warning (multi-func-
tion) switch as required.
INSTRUMENT PANEL CIGAR LIGHTER
For complete circuit diagrams, refer to Horn/Ci-
gar Lighter/Power Outlet in the Contents of
Group 8W - Wiring Diagrams.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, REFER TO
RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY
STEERING WHEEL,
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
(1) Check the fused ignition switch output (run/ac-
cessory) fuse in the junction block. If OK, go to Step
2. If not OK, repair the shorted circuit or component
as required and replace the faulty fuse.
(2) Turn the ignition switch to the On position.
Check for battery voltage at the fused ignition switch
output (run/accessory) fuse in the junction block. If
OK, go to Step 3. If not OK, repair the open fused
ignition switch output (run/accessory) circuit to the
ignition switch as required.
