Step

Value

Yes

No

1

CHECK FUSE.
Remove and visually check fuse No. 6 (in the
main fuse box).
Is the fuse blown?

The fuse is not blown.

Go to step 2.

Replace the fuse
with a new one.

2

CHECK KEY WARNING SWITCH CIRCUIT.
1) Disconnect the keyless entry control mod-

ule harness connector.

2) Insert the key into the ignition switch.

(LOCK position)

3) Measure the voltage between the harness

connector terminal and chassis ground.

Connector & terminal

(B176) No. 1 (+) — chassis ground (–):

Does the measured value exceed the spec-
ified value?

10 V

Go to step 3.

Go to step 4.

3

CHECK KEY WARNING SWITCH CIRCUIT.
1) Remove the key from the ignition switch.
2) Measure the voltage between the harness

connector terminal and chassis ground.

Connector & terminal

(B176) No. 1 (+) — chassis ground (–):

Is the measured value same as the speci-
fied value?

0 V

The key warning
switch is OK.

Go to step 4.

4

CHECK KEY WARNING SWITCH.
1) Disconnect the key warning switch harness

connector.

2) Insert the key into the ignition switch.

(LOCK position)

3) Measure the resistance between the key

warning switch terminals.

Terminal

No. 1 — No. 2:

Is the measured value less than the speci-
fied value?

1

Ω

Go to step 5.

Replace key warn-
ing switch.

5

CHECK KEY WARNING SWITCH.
1) Remove the key from the ignition switch.
2) Measure the resistance between the key

warning switch terminals.

Terminal

No. 1 — No. 2:

Does the measured value exceed the spec-
ified value?

1 M

Ω

Check the follow-
ing:

•

Harness for

open circuits or
shorts between
the key warning
switch and fuse

•

Harness for

open circuits or
shorts between
the keyless entry
control module
and key warning
switch

Replace key warn-
ing switch.

9. CHECK ROOM LIGHT OPERATION

Step

Value

Yes

No

1

CHECK HAZARD LIGHT OPERATION.
Make sure the hazard light blinks when hazard
switch is turned ON.
Does hazard light brink?

Hazard light blinks.

Go to step 2.

Check hazard light
circuit.

2

CHECK OUTPUT SIGNAL.
1) Remove the key from ignition switch.
2) Close all doors and rear gate.
3) Measure voltage between keyless entry

control module harness connector terminal
and chassis ground when LOCK or OPEN
button of transmitter is pressed.

Connector & terminal

(B176) No. 12, No. 13 (+) — Chassis
ground (

−

):

Does the measured value exceed the spec-
ified value?

10 V

Check harness for
open or short
between keyless
entry control mod-
ule and turn signal
lights.

Replace the key-
less entry control
module.

Step

Value

Yes

No

1

CHECK ROOM LIGHT OPERATION.
Make sure the room light illuminates when the
room light switch is turned ON.
Does the room light illuminate?

Room light illuminates.

Go to step 2.

Check the room
light circuit.

2

CHECK HARNESS BETWEEN ROOM LIGHT
AND KEYLESS ENTRY CONTROL MODULE.
1) Disconnect the keyless entry control mod-

ule harness connector and room light har-
ness connector.

2) Measure the resistance between the key-

less entry control module harness connec-
tor terminal and the room light harness
connector terminal.

Connector & terminal

(B176) No. 11 — (R52) No. 2:

Is the measured value less than the speci-
fied value?

10

Ω

The room light
operation circuit is
OK.

Check the harness
for open circuits or
shorts between
the keyless entry
control module
and room light.

10.CHECK IGNITION SWITCH ILLUMINATION CIRCUIT

Step

Value

Yes

No

1

CHECK IGNITION SWITCH ILLUMINATION
POWER SUPPLY.
1) Disconnect the ignition switch illumination

harness connector.

2) Measure voltage between the ignition

switch illumination harness connector ter-
minal and chassis ground.

Connector & terminal

(B224) No. 2 (+) — Chassis ground (

−

):

Does the measured value exceed the spec-
ified value?

10 V

Go to step 2.

Check harness for
open circuit or
shorts between
the ignition switch
illumination and
fuse.

2

CHECK HARNESS BETWEEN IGNITION
SWITCH ILLUMINATION AND KEYLESS EN-
TRY CONTROL MODULE.
1) Disconnect the keyless entry control mod-

ule harness connector.

2) Measure the resistance between the key-

less entry harness connector terminal and
the ignition switch illumination harness con-
nector.

Connector & terminal

(B176) No. 11 — (B224) No. 1:

Is the measured value less than the speci-
fied value?
