Diagnosis

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 battery

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

An intermittent may be caused by the following:

• Poor connections.
• Miss routed harness.
• Rubbed through wire insulation.
• Broken wire inside the insulation.

Check for the following conditions:

• Poor connection at ACU-Inspect harness

connectors for backed out terminals, improper

mating, broken locks, improperly formed or

damaged terminals, and poor terminal to wire

connection.

• Damaged harness-Inspect the wiring harness for

damage.

If the harness appears to be OK, observe the data

display on the Tech2 while moving connectors and

wiring harnesses related to the switch or actuator.

A change in the display will indicate the location of

the fault.

If DTC cannot be duplicated, the information

included in the Failure Records data can be useful

in determined vehicle mileage since the DTC was

last set.

If it is determined that the DTC occurs

intermittently, performing the DTC Diagnostic

Chart may isolate the cause of the fault.

NOTE: Breakage of antitheft fuse does not operate
antitheft system. Check LED 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.
• Antitheft programming functions.

Must be programmed antitheft system.

• Registration for security code, antitheft control unit

parts number.

• Key switch operation.

Antitheft system may detect a history DTC by the

timing of ON-OFF of a key switch.

• Active the antitheft system.
• Keyless entry system is malfunction.
• Immobilizer system is malfunction.

Check the operation

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