8U - 4 CHIME/BUZZER WARNING SYSTEMS
DIAGNOSIS AND TESTING (Continued)
Removal and Installation section of Group 8E -
Instrument Panel Systems
Unplug the 14-way CTM wire harness connector.
Check for continuity between the driver door ajar
switch sense circuit cavity of the 14-way CTM wire
harness connector and a good ground. There should
be no continuity. If OK, go to Step 5. If not OK,
repair the short circuit as required.
(5) Check for continuity between the driver door
ajar switch sense circuit cavities of the 14-way CTM
wire harness connector and the driver door latch
wire harness connector. There should be continuity. If
OK, see Key-In Ignition Switch and/or Headlamp
Switch in the Diagnosis and Testing section of this
group. If not OK, repair the open circuit as required.
KEY-IN IGNITION SWITCH
For circuit descriptions and diagrams, refer to
8W-40 - Instrument Cluster or 8W-44 - Interior
Lighting in 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) Disconnect and isolate the battery negative
cable. Remove the steering column shrouds. Refer to
Group 8D - Ignition Systems for the procedures.
Unplug the key-in ignition switch wire harness con-
nector from the ignition switch.
(2) Check for continuity between the key-in igni-
tion switch sense and ground terminals of the key-in
ignition switch. There should be continuity with the
key in the ignition lock cylinder, and no continuity
with the key removed from the ignition lock cylinder.
If OK, go to Step 3. If not OK, replace the faulty igni-
tion switch assembly.
(3) Open the driver door. Check for continuity
between the ground circuit cavity of the key-in igni-
tion switch wire harness connector and a good
ground. There should be continuity. If OK, go to Step
4. If not OK, repair the open circuit to the driver
door ajar switch as required.
(4) Remove the Central Timer Module (CTM) from
its mounting bracket to access the CTM wire harness
connectors. Refer to Central Timer Module in the
Removal and Installation section of Group 8E -
Instrument Panel Systems
Unplug the 14-way CTM wire harness connector.
Close the driver door. Check for continuity between
the key-in ignition switch sense circuit cavity of the

CTM wire harness connector and a good ground.
There should be no continuity. If OK, go to Step 5. If
not OK, repair the short circuit as required.
(5) Check for continuity between the key-in igni-
tion switch sense circuit cavities of the key-in igni-
tion switch wire harness connector and the 14-way
CTM wire harness connector. There should be conti-
nuity. If OK, test the CTM as described in this group.
If not OK, repair the open circuit as required.
HEADLAMP SWITCH
For circuit descriptions and diagrams, refer to
8W-45 - Central Timer Module in Group 8W - Wiring
Diagrams.

(1) Disconnect and isolate the battery negative
cable. Remove the headlamp switch from the instru-
ment panel. Refer to Headlamp Switch in the
Removal and Installation section of Group 8E -
Instrument Panel
Unplug the headlamp switch wire harness connec-
tors. Check for continuity between the driver door
ajar switch sense circuit cavity of the headlamp
switch wire harness connector and a good ground.
There should be continuity with the driver door open,
and no continuity with the driver door closed. If OK,
go to Step 2. If not OK, repair the circuit to the
driver door ajar switch as required.
(2) Remove the Central Timer Module (CTM) from
its mounting bracket to access the CTM wire harness
connectors. Refer to Central Timer Module in the
Removal and Installation section of Group 8E -
Instrument Panel
Unplug the 14-way CTM wire harness connector.
Remove the key from the ignition lock cylinder.
Check for continuity between the key-in ignition
switch sense circuit cavity of the 14-way CTM wire
harness connector and a good ground. There should
be no continuity. If OK, go to Step 3. If not OK,
repair the short circuit as required.
(3) Check for continuity between the key-in igni-
tion switch sense circuit cavities of the 14-way CTM
wire harness connector and the headlamp switch
wire harness connector. There should be continuity. If
OK, go to Step 4. If not OK, repair the open circuit
as required.
