IMMOBILIZER SYSTEM 11A-31

Diagnostic procedure


Once the cause of DTC is repaired or gone,
engine can be operated normally, and present
DTC becomes history code.


History code is canceled by no repeat failure on 25
consequence ignition key on afterward.


History code cannot be canceled by batter
y
connector disconnected.
Clearing Diagnostic Trouble Codes
IMPORTANT:
Do not clear DTCs unless directed to do
so by the service information provided for each
diagnostic procedure. When DTCs are cleared, the
Failure Record data which may help diagnose an
intermittent fault will also be erased from memory.
Verifying Vehicle Repair
Verification of vehicle repair will be more
comprehensive for vehicles with immobilizer system
diagnostic. Following a repair, the technician should
perform the following steps:
1.
Review and record the Fail Records for the DTC
which has been diagnosed.
2.
Clear DTC(s).
3.
Operate the vehicle within conditions noted in the
Fail Records.
4.
Monitor the DTC status information for the DTC
which has been diagnosed until the diagnostic test
associated with that DTC runs.
Following these steps are very important in verifying
repairs on immobilizer systems. Failure to follow these
steps could result in unnecessary repairs.
Diagnostic Aids
Check the condition for system parts.



Installation condition, poor connection, damage,
system parts malfunction. Harness, Fuse, Relay,
Immobilizer coil (antenna), Key, Meter, Immobilize
r
control unit (ICU), Engine control module (ECM).
NOE: Breakage of immobilizer fuse does not operate
immobilizer system. Check engine lamp flashes at this
time.

Check the Electro-Magnetic Interference (EMI)



Location of vehicle check

Move the vehicle to a new location and perform
the check again.


Non-OEM Parts.

Switch is "OFF" or remove the Non-OEM parts and
perform the check again.


Other

Remove the accessory and another key from key.

Check the other items.



Battery voltage is low.


Immobilizer programming functions.

Must be programmed immobilizer system.


Registration for security code, immobilizer control
unit parts number.


Key switch operation.

Immobilizer system may detect a history DTC b
y
the timing of ON-OFF of a key switch.


Active the immobilizer system.


Keyless entry system is malfunction.


Anti theft system is malfunction.

Check the operation

Check the operation "Lock / unlock" by using transmitte
r
(key) on the vehicle.
