Immobilizer system — identification code registration method (Mitsubishi Pajero 4)

After purchasing a new ignition key or replacing the immobilizer electronic control unit, you must register the identification codes for each new key in the immobilizer control unit. (The maximum number of codes that can be registered is eight). In addition, after replacing the immobilizer electronic control unit, you need to use the MUT-III device to register the password set in the immobilizer electronic control unit (Similar information is provided in the MUT-III Operating Manual).

Please note: When registering new identification codes, all previously registered codes will be erased. In this regard, you need to have all the ignition keys available, the codes of which have already been registered earlier.

1. Connect MUT-III to the diagnostic connector.

Caution: Connecting and disconnecting the MUT-III must always be done with the ignition off.

2. Use the ignition key you are going to register to turn the ignition switch to the ON position.

3. Use MUT-III to register the identification code. If you register two or more codes, use the next ignition key you are going to register to turn the ignition switch to the ON position without disconnecting the MUT-III.

4. Disconnect the MUT-III. This will complete the registration operation.
