A. Immobilizer Override Code

The Immobilizer system has an override feature so the vehicle may be started with a properly cut non-transponder key in the event all registered keys are lost. The system allows for 2 start attempts using the temporary key and the override code so the vehicle can be driven to the dealership where new transponder keys can be cut and registered with a new ID code.

An override code is necessary to operate the override function. The customer should have a card presented to them at the time of purchase which has a record of the vehicle's override code.





If the card shown above is not available, you can retrieve the override code by using the following procedures:





1. Locate the Immobilizer ECU serial number (S/N: --------) on the vehicle. Record this serial number.





^ Eclipse, Eclipse Spyder, & Galant - Serial number tag is found in the glove box area.





^ Diamante - Serial number tag is on the driver's-side trunk lid hinge bar.





^ Montero & Montero Sport - Serial number tag is on the front of the driver's-side B-pillar.

2. Using the Immobilizer ECU serial number, use MEDIC (or one of your dealership's DDL systems) to call up Advance Diamond Net System (ADNS) and retrieve the Immobilizer Override Code number. Record this code. With this code, you can now proceed with the following procedures for starting the vehicle using the Immobilizer Override code. It is suggested that you give the customer this code in case it is needed again in the future.
