IMMOBILIZER (DIAGNOSTIC)
General Description
2. General Description
A: CAUTION
CAUTION:
The airbag system wiring harnesses rout-
ed near the immobilizer control module. All
airbag system wiring harness and connec-
tors 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 immobilizer
control module.
While diagnostic items are being checked, do
not operate radios, portable telephones, etc.
which emit electromagnetic waves near or
inside the vehicle.
When the ignition switch is being turned ON or
OFF while diagnostic items are being checked, do
not allow keys with different ID codes close to the
ignition switch. If the ignition key is in a key
holder, remove it from the holder before carrying
out diagnoses. When repeatedly turning the ignition switch
to ON or OFF while diagnostic items are being
checked, it should be switched in cycles of
“ON” for at least 5 seconds → “OFF” for at least
8 seconds.
If the engine fails to start with a registered
ignition key, detach the ignition key from ignition
switch and wait for approx. 1 second until immobi-
lizer warning light begins to flash. Start the engine
again.
Before checking the diagnostic items, obtain
all keys for the vehicle to be checked possessed
by owner.
