15.CHECK IGNITION SWITCH.
CAUTION:
When the ignition key lock is replaced, all ignition keys also must be registered. (Refer to the “IMMO-
BILIZER TEACHING OPERATION MANUAL”.)
Step Check Yes No
1CHECK FUSIBLE LINK.
Remove the fusible link main SBF and SBF-6
(in main fuse box), and visually check.
Is the fusible link blown out? Replace the fus-
ible link main SBF
or SBF-6. If the
replaced fusible
link has blown out
easily, repair the
short circuit
between the fus-
ible link and the
ignition switch.
Go to step 2.
2CHECK FOR POWER SUPPLY OF IGNITION
SWITCH.
1) Disconnect the ignition switch harness con-
nector.
2) Measure the voltage between harness con-
nector terminal and chassis ground.
Connector & terminal
(B72) No. 3 (+) — Chassis ground (– ):
Is the voltage more than 10 V? Go to step 3.Check the harness
for open circuits
and shorts
between the igni-
tion switch and
fusible link.
3CHECK IGNITION SWITCH.
1) Insert the ignition key into ignition switch,
and turn the each position.
2) Measure the resistance between ignition
switch terminals.
Connector & terminal
No. 3 — No. 4 (ACC position):
No. 3 — No. 4 — No. 6 — No. 1 (ON posi-
tion):
No. 3 — No. 6 — No. 1 — No. 2 (ST posi-
tion):
Is the resistance less than 1 Ω
when turning the ignition key to
each position?
Ignition switch is
normal.
Replace the igni-
tion switch with a
new part.
