COIL REMOVAL/INSTALLATION

• Do not remove the coil unless you are replacing it.

• When only the coil is replaced, the immobilizer system reprogram procedure is not necessary.

1. Disconnect the negative battery cable.

2. Remove the column cover.

3. Remove in the order indicated in the table.

4. Install in the reverse order of removal.

• When an error occurs during the reprogram procedures, ecept 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 PCM cannot be changed from one car to another. If an PCM is replaced with one from another car,

the engine will not start.

• The PCM should not be newly replaced as a trial during troubleshooting. If this is done, the ID and code

word will be programmed into the new unit and it cannot be used for other cars even if you find that the old

unit was normal.

• 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 net key.

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

stopped after registering two keys.

Key Replacement or Addition

When the customer has two or more valid keys
