CORRECTION
1. Check for continuity between the driver door
ajar switch sense circuit cavities of the connector
for the driver side front door ajar switch and the
instrument panel wire harness connector
(Connector C2) for the ignition switch. Repair the
driver door ajar switch sense circuit, if required.
2. Check for continuity between the key-in ignition
switch sense circuit cavities of the instrument
panel wire harness connector (Connector C2) for
the ignition switch and the instrument panel wire
harness connector for the CTM. Repair the key-in
ignition switch sense circuit, if required.
3. Check for continuity between the two terminals
in the ignition switch C2 connector receptacle.
There should be continuity with a key in the
ignition lock cylinder. Replace the faulty ignition
switch, if required.

ajar switch sense circuit cavities of the connector
for the driver side front door ajar switch and the
instrument panel wire harness connector
(Connector C1) for the headlamp switch. Repair
the driver door ajar switch sense circuit, if
required.
2. Check for continuity between the key-in ignition
switch sense circuit cavities of the instrument
panel wire harness connector (Connector C1) for
the headlamp switch and the instrument panel
wire harness connector for the CTM. Repair the
key-in ignition switch sense circuit, if required.
3. Check for continuity between the driver door
ajar switch sense terminal and the key-in ignition
switch sense terminal in the headlamp switch C1
connector receptacle. There should be continuity
with the headlamp switch in the On position.
Replace the faulty headlamp switch, if required.
1. With the instrument panel wire harness
connector (Connector C1) for the headlamp
switch, the instrument panel wire harness
connector (Connector C2) for the ignition switch,
and the instrument panel wire harness connector
for the CTM all disconnected, there should be no
continuity between the key-in ignition switch
sense circuit and a good ground. Repair the
key-in ignition switch sense circuit, if required.
2. Replace the faulty CTM, if required.
