IMMOBILIZER SYSTEM-RELATED PARTS PROGRAMMING

Foreword

  • When replacing immobilizer system-related parts or programming an additional remote transmitter, or clearing a remote transmitter, 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 remote transmitter, communication between the remote transmitter 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 remote transmitter 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

    • 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.

  • If a remote transmitter is near the vehicle during immobilizer system-related parts programming, it may be programmed mistakenly. Keep the remote transmitter 1 m away from the vehicle unless indicated in the procedure.

  • The SSU in the procedure indicates the start stop unit. In addition, the advanced key indicates the remote transmitter.

NOTE:

  • Two or more remote transmitters must be programmed for the engine to start.

  • A maximum of six remote transmitters can be programmed to one vehicle.

  • The number of programmed key ID numbers can be verified using the M-MDS.

  • Do not select any screen menu other than the ones indicated in the procedure during M-MDS operation.

  • When programming the immobilizer system-related parts, the incode must be searched.

Selection of Procedure for Immobilizer System-Related Parts Programming

1. Verify that the ROOM fuse, AT fuse, and SRS2/ESCL fuse are installed.

2. Select the applicable programming procedure from the service content of the immobilizer system-related parts.
