B: CAUTION
 Before disassembling or reassembling parts,
always disconnect the ground cable from battery.
When repairing radio, control module, etc. which
are provided with memory functions, record the
memory contents before disconnecting the
ground cable from battery. Otherwise, these
contents are cancelled upon disconnection.
 Reassemble parts in the reverse order of
disassembly procedure unless otherwise
indicated.
 Adjust parts to specifications contained in
this manual if so designated.
Connect the connectors and hoses securely
during reassembly.
After reassembly, ensure all functional parts
operate smoothly.
Airbag system wiring harness is routed near
the electrical parts and switch.
 All airbag system wiring harness and
connectors are colored yellow. Do not use
electrical test equipment on these circuits. Be careful not to damage the airbag system
wiring harness when servicing the ignition key
cylinder.

3. CHECK POWER SUPPLY AND GROUND CIRCUIT
Step Check Yes No
1 CHECK FUSE.
Remove and visually check the fuse No. 2 (in
the main fuse box).In the fuse blown out? Replace the fuse
with a new one.Check the power
supply and ground
circuit. SL-10, CHECK

System.>
Step Check Yes No
1 CHECK POWER SUPPLY.
1) Disconnect the keyless entry control mod-
ule or double lock module harness connector.
2) Measure the voltage between the harness
connector terminal and chassis ground.
Connector & terminal
Without double lock:
(B176) No. 5, 16 (+) — Chassis ground (
−
):
With double lock:
(B324) No. 7, 8 (+) — Chassis ground (
−):Is the voltage more than 10 V? Go to step 2.Check the harness
for open circuits or
shorts between
the keyless entry
control module or
double lock mod-
ule and the fuse.
2 CHECK GROUND CIRCUIT.
Measure the resistance between the harness
connector terminal and chassis ground.
Connector & terminal
Without double lock:
(B176) No. 6, 14 — Chassis ground:
With double lock:
(B324) No. 9 — Chassis ground:Is the resistance less than 10
Ω?The power supply
and ground circuit
is OK.Repair the har-
ness.
