1
CHECK IGNITION SWITCH ILLUMINATION
POWER SUPPLY.
1) Disconnect the ignition switch illumination
harness connector.
2) Measure the voltage between ignition
switch illumination harness connector terminal
and chassis ground.
Connector & terminal
(B224) No. 1 (+) — Chassis ground (
−
):
Is the voltage more than 10 V? Go to step
Check the harness
for open circuit or
shorts between
ignition switch illu-
mination and fuse.
2
CHECK HARNESS BETWEEN IGNITION
SWITCH ILLUMINATION AND KEYLESS EN-
TRY CONTROL MODULE (WITHOUT DOU-
BLE LOCK) OR DOUBLE LOCK MODULE
(WITH DOUBLE LOCK).
1) Disconnect the keyless entry control mod-
ule or double lock module harness connector.
2) Measure the resistance between keyless
entry or double lock module harness connector
terminal and ignition switch illumination har-
ness connector.
Connector & terminal
Without double lock:
(B176) No. 11 — (R224) No. 1:
With double lock:
(B325) No. 1 — (R224) No. 2:
Is the resistance less than 10
Ω
?
Check the ignition
switch illumina-
tion. If NG, replace
the ignition switch
illumination.
Repair the har-
ness.

1
CHECK OUTPUT SIGNAL.
Measure the voltage between the keyless
entry control module harness connector termi-
nal and chassis ground when OPEN button of
transmitter is pressed.
Connector & terminal
(B176) No. 17 (+) — Chassis ground (
−
):
Is the voltage more than 10 V? Go to step
Replace the key-
less entry control
module.
2
CHECK OUTPUT SIGNAL.
Measure the voltage between the keyless
entry control module harness connector termi-
nal and chassis ground when LOCK button of
transmitter is pressed.
Connector & terminal
(B176) No. 18 (+) — Chassis ground (–):
Is the voltage more than 10 V? Replace the dou-
ble lock module.
Check the harness
for open circuit or
shorts between
the keyless entry
control module
and double lock
module.
