THEFT-DETERRENT SYSTEM

W Terminal Inspection

1. Connect SST (WDS or equivalent) to the vehicle

DLC-2 16-pin connector.

2. Access and monitor RPM of PID using SST

(WDS or equivalent).

• If engine speed signal normal, go to next step.

• If engine speed signal abnormal, inspect the

ABS (ABS/TCS) HU/CM, DSC HU/CM and
related wiring harness.

3. Inspect for continuity between the ABS (ABS/

TCS) HU/CM terminal X and the theft-deterrent
control module terminal W, or DSC HU/CM
terminal AB and the theft-deterrent control
module terminal W using an ohmmeter.

• If not continuity, replace the related wiring

harness.

• If wiring harness is normal, replace the theft-deterrent control.

IMMOBILIZER SYSTEM REPROGRAM PROCEDURE

A6E812267000W01

Caution

• Do not perform key registration or start the engine under the following conditions. Doing so could

result in a key registration error or the engine not starting even with a correctly registered key.
— If a large, metal object is close to a valid key
— If an electrical device is close to a valid key
— If two or more valid keys are on the same key ring

Note

• When an error occurs during the reprogram procedures, except when the PCM is replaced, repeat the

procedure from Step 1. If you still cannot reprogram, confirm how many keys can start the engine. Then,
perform the key replacement or addition reprogram procedure according to the valid key number.

• To make a copy of the key or replace the immobilizer system component parts (the key(s), and/or PCM),

the customer should bring all keys to the dealer. This is because the previously programmed key IDs are
erased when reprogramming the key IDs into the PCM.

• The immobilizer system cannot be deactivated.

• Confirm that all keys registered can start the engine after the reprogram procedure. When confirming, wait

for more than 5 seconds before inserting the next key.

• When the customer does not need to register more than two keys, the following procedures can be

stopped after registering two keys.

• If the engine is started during the key registration procedure, the key registration mode will be erased.

Therefore, do not start the engine until the key registration procedure for all the necessary keys is
finished.

• A maximum of 8 keys can be registered for one vehicle.

• Two or more valid keys are necessary to start engine.

Note

• If no specific time interval is given, each step should be performed within 30 seconds of the previous

step.

1. Cut new transponder-equipped key(s).
2. Using key 1, turn ignition switch to ON position.

(1) Observe illumination of security light in instrument cluster.
(2) After the security light turns off (after approx. 3 seconds from when ignition switch is turned to ON

position), turn key 1 to LOCK position within approx. 4 seconds and remove it from the steering lock.

3. Repeat Step 2 with key 2.
4. Repeat Step 2 with key 3.
5. If there are 4—8 keys (valid and/or new keys), repeat Step 2.
6. Verify that the engine starts using the registered key.

When the customer has only one or no valid key

• If only one or no valid key is available, use the SST (WDS) to register additional keys. (See

Key registration using SST (WDS)

Note

• Additional keys can be registered without having to erase the key codes already registered.

• If 8 keys have already been registered, this procedure cannot be used to register a key. To register a key

under this condition, it is necessary to first erase all the key codes. (See

T–92 Key Replacement

)

1. Cut new transponder equipped key(s) if necessary.
2. Connect the SST (WDS).
3. Using key 1, turn ignition switch to ON position.

• Valid key: The security light illuminates, then turns off after approx. 3 seconds.

• New key: The security light flashes rapidly for approx. 1 minute and start displaying the DTC 15 (WDS or

equivalent: DTC B1601).

(1) Perform security access approval. (See

T–92–1 Security Access Procedure

)

(2) Select "Program additional ignition key".
(3) Turn key 1 to LOCK position and remove from the steering lock.

4. Using key 2, turn ignition switch to ON position.

(1) Select "Program additional ignition key".
(2) Turn key 2 to LOCK position and remove from the steering lock.

5. If there are 3—8 keys (new keys), repeat Step 4.
6. After reprogramming, clear DTCs of PCM with SST (WDS).
7. Verify that the engine starts using the registered key.
