Step Check Yes No
1 CHECK TRANSMITTER BATTERY.
1) Remove the battery from transmitter.
2) Check the battery voltage.
NOTE:
If the transmitter battery voltage is 2.5 V or less,
the range of transmission becomes very short.Is the voltage more than 2.5 V? If further inspec-
tion is necessary,
refer to “SYMP-
TOM CHART”.

Step Check Yes No
1 CHECK FUSE.
Remove and visually check the fuse No. 2 (in
the main fuse box), No. 3 (in the fuse and relay
box) and SBF-6 (in the main fuse box)Is the fuse blown out? Replace the fuse
with a new one.Check the power

IMMOBILIZER (DIAGNOSTIC)
Diagnostics Chart for Immobilizer Warning Light
Step Check Yes No
1 CHECK IMMOBILIZER WARNING LIGHT.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector from
IMM ECM.
3) Connect a resistor (750 Ω) between IMM
ECM harness connector terminal No. 9 and
chassis ground.Does the immobilizer warning
light illuminate?Go to step 2.Go to step 5.
2 CHECK IMM ECM GROUND CIRCUIT.
Measure the resistance between IMM ECM
harness connector terminal and chassis
ground.
Connector & terminal
(B141) No. 2, No. 3 — Chassis ground:Is the resistance less than 10
Ω?Go to step 3.Repair the open
circuit of IMMECM
ground circuit.
3 CHECK IMM ECM IGNITION CIRCUIT.
1) Turn the ignition switch to ON. (engine
OFF.)
2) Measure the voltage between IMM ECM
harness connector terminal and chassis
ground.
Connector & terminal
(B141) No. 12 (+) — Chassis ground(
−):Is the voltage more than 10 V? Go to step 4.Check the harness
for open or short
between IMM
ECM and ignition
switch.
4 CHECK IMM ECM POWER SUPPLY CIR-
CUIT.
1) Turn the ignition switch to OFF.
2) Measure the voltage between IMM ECM
harness connector terminal and chassis
ground.
Connector & terminal
(B141) No. 10, No. 11 (+) — Chassis
ground(
−):Is the voltage more than 10 V? Replace the IMM
ECM
Control Module.>
and then replace
all ignition keys
(including the tran-
sponder). Then
perform teaching
operation. Refer to
teaching opera-
tion manual (Pub.
No. S0820GZ).Check the harness
for open or short
between IMM
ECM and fuse.
5 CHECK COMBINATION METER CIRCUIT.
1) Remove the combination meter.
2) Measure the voltage between combination
meter harness connector terminal and chassis
ground.
Connector & terminal
(i10) No. 8 (+) — Chassis ground (
−):Is the voltage more than 10 V? Go to step 6.Check the harness
for open or short
between combina-
tion meter and
fuse.
6 CHECK COMBINATION METER CIRCUIT.
Measure the resistance between IMM ECM
harness connector terminal and combination
meter harness connector terminal.
Connector & terminal
LHD model
(B141) No. 9 — (i12) No. 4:
RHD model
(B141) No. 9 — (i11) No. 5:Is the resistance less than 10
Ω?Faulty LED.
Replace the com-
bination meter

Step Check Yes No
1 CHECK POWER SUPPLY CIRCUIT.
1) Disconnect the harness connector from key
warning switch.
2) Measure the voltage between key warning
switch harness connector terminal and chassis
ground.
Connector & terminal
(B74) No. 2 (+) — Chassis ground (
−):Is the voltage more than 10 V? Go to step 2.Check the harness
for open or short
between key warn-
ing switch and
fuse.
2 CHECK KEY WARNING SWITCH.
1) Insert the ignition key to the ignition switch.
(OFF or ACC position)
2) Measure the resistance between key warn-
ing switch connector terminals.
Te r m i n a l
No. 1 — No. 2:Is the resistance less than 1
Ω?Go to step 3.Replace the key
warning switch.
3 CHECK KEY WARNING SWITCH.
1) Remove the ignition key from the ignition
switch.
2) Measure the resistance between key warn-
ing switch connector terminals.
Te r m i n a l
No. 1 — No. 2:Is the resistance more than
1 MΩ?Go to step 4.Replace the key
warning switch.
4 CHECK HARNESS BETWEEN KEY WARN-
ING SWITCH AND IMM ECM.
1) Disconnect the harness connector from key
warning switch.
2) Disconnect the harness connector from
IMM ECM.
3) Measure the resistance between key warn-
ing switch harness connector terminal and
IMM ECM harness connector terminal.
Connector & terminal
(B74) No. 1 — (B141) No. 4:Is the resistance less than 10
Ω?Replace the IMM
ECM
Control Module.>
and then replace
all ignition keys
(including the tran-
sponder). Then
perform teaching
operation. Refer to
teaching opera-
tion manual (Pub.
