IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING

id091400441900

Foreword

• When replacing immobilizer system-related parts or programming an additional key, program the immobilizer system-related parts so that the system operates normally. For immobilizer system-related parts programming, select the programming procedures according to the service. (See Selection of Procedure for Immobilizer System-Related Parts Programming.)

  Caution
  • The engine cannot be started if any step or procedure for each service operation is skipped. Perform all procedures in the order of the steps.
  • If any metallic or magnetic object is near the key, communication between the key and the vehicle may be obstructed, resulting in a failure to program the immobilizer system-related parts. Remove any metallic or magnetic objects, such as key holders, from the key when programming immobilizer system-related parts.
  • If any of the following devices are inside the vehicle, programming of immobilizer system-related parts may fail. Do not bring any of the following devices or similar products inside the vehicle when programming immobilizer system-related parts.
    ― M-MDS (IDS)
    ― Personal computer
    ― Devices that can send/receive radio waves
  • If the engine is started during immobilizer system-related parts programming, the programming mode cancels. Therefore, do not start the engine unless indicated in the procedure. Repeat the procedure from the beginning if the engine is started during the immobilizer system-related parts programming.

  Note
  • The “Valid key” referred to in this manual indicates the key that can start the engine.
  • Two or more key ID numbers must be programmed for the engine to start.
  • A maximum of eight key ID numbers can be programmed for one vehicle.
  • The number of programmed key ID numbers can be verified using the M-MDS (IDS).
  • Do not select any screen menu other than the ones indicated in the procedure during M-MDS (IDS) operation.
