GENERAL OPERATION INTRODUCTION The Renault Immobiliser system uses either Infra Red or Radio Frequency for Plip key operation and transponder key technology for key entry and starting. The Infra Red and RF systems uses a rolling code system to ensure the vehicle system cannot be breached. Activation of the Immobiliser system is indicated by the LED indicator in the Instrument cluster. If there is a fault in the system, an emergency access code can be used to dis-able the system using the central door locking button or key and the LED to enter the code. On petrol vehicles the immobiliser is carried out by the Fuel Injection system and on Die-sel systems it is carried out by the coded solenoid valve. The immobiliser system automatically sets itself after 10 minutes if both doors are closed, this can be 30 minutes in other countries. If the ignition is switched OFF and one of the front doors is opened, then the immobiliser sets itself after 1 minute, in other countries it can be 10 minutes. To disarm the system the doors must be locked and unlocked using the plip key func-tions. Only 2 plips can be operated on this system.
