Diagnostics Chart for Security Indicator Light
IMMOBILIZER (DIAGNOSTICS)
Step Check Yes No
1 CHECK SECURITY INDICATOR LIGHT.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector from
body integrated unit.
3) Connect the resistor (100
Ω
) between the
body integrated unit harness connector termi-
nal (i84) No. 33 and chassis ground.
Does the security indicator light
illuminate? Go to step 2 . Go to step 5 .
2 CHECK BODY INTEGRATED UNIT GROUND
CIRCUIT.
Measure the resistance between body inte-
grated unit harness connector terminal and
chassis ground.
Connector & terminal
(B280) No. 22 — Chassis ground:
(B281) No. 8, No. 9 — Chassis ground:
Is the resistance less than 10
Ω
?
Go to step 3 . Repair the open
circuit of body inte-
grated unit ground
circuit.
3 CHECK BODY INTEGRATED UNIT IGNITION
CIRCUIT.
1) Turn the ignition switch to ON. (Engine OFF)
2) Measure the voltage between body inte-
grated unit harness connector terminal and
chassis ground.
Connector & terminal
(i84) No. 1 (+) — Chassis ground (–):
Is the voltage 10 V or more? Go to step
4
. Check the harness
for open or short
circuit between
body integrated
unit and ignition
switch.
4 CHECK BODY INTEGRATED UNIT POWER
SUPPLY CIRCUIT.
1) Turn the ignition switch to OFF.
2) Measure the voltage between body inte-
grated unit harness connector terminal and
chassis ground.
Connector & terminal
(B280) No. 7 (+) — Chassis ground (–):
(B281) No. 2 (+) — Chassis ground (–):
Is the voltage 10 V or more? Replace the body
integrated unit
<Ref. to SL-51,
Body Integrated
Unit.> and replace
all the ignition keys
(including tran-
sponder). Execute
the registration
procedure next.
Refer to the “REG-
ISTRATION MAN-
UAL FOR
IMMOBILIZER”. Check the harness
for open or short
circuit between
body integrated
unit and fuse.
5 INSPECT WARNING BOX CIRCUIT.
1) Remove the warning box. <Ref. to IDI-18,
REMOVAL, Warning Box.>
2) Measure the voltage between the warning
box harness connector terminal and chassis
ground.
Connector & terminal
(i116) No. 1 (+) — Chassis ground (–):
Is the voltage 10 V or more? Go to step 6 . Check the harness
for open or short
circuit between
warning box and
fuse.
6 INSPECT WARNING BOX CIRCUIT.
Measure the resistance between body inte-
grated unit harness connector terminal and
warning box harness connector terminal.
Connector & terminal
(i84) No. 33 — (i116) No. 2:
Is the resistance less than 10
Ω
?
LED bulb malfunc-
tion. Replace the
warning box. <Ref.
to IDI-18,
REMOVAL, Warn-
ing Box.> Repair the harness
or connector.
