Immobilizer System-Related Parts Programming

CAUTION:

To prevent a failure in programming the immobilizer system-related parts, do not implement other functions of the M-MDS (including tab operation) when programming immobilizer system-related parts.
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 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 otherwise in the procedure. If the vehicle is equipped with the following devices, programming of the immobilizer system-related parts may not be normal. 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 and receive radio waves
Do not depress the brake pedal unless instructed to do so because the ignition may be accidentally switched ON (engine on).
To prevent a failure in programming the immobilizer system-related parts, turn off (disable) the pacemaker radio wave interference prevention function and the power saving function of the remote transmitter when programming immobilizer system-related parts.

NOTE:

When programming the immobilizer system-related parts, the incode must be searched.
Two or more remote transmitters must be programmed to switch the ignition ON (engine on).
A maximum of six remote transmitters can be programmed to one vehicle.
Before beginning the procedure, verify that the customer has provided all of the remote transmitters for the vehicle.

Select the following items according to the maintenance contents.

Perform immobilizer system-related part programming according to the directions on the M-MDS.
Touch the push button start with the emblem side of the remote transmitter and verify that the engine starts.

NOTE:
- Verify that the engine starts with all of the programmed remote transmitters.
Verify that the engine starts while the remote transmitter is not in contact with the push button start.
- If the engine does not start, check for DTCs. (See DTC INSPECTION .)
Verify that no DTC is displayed. (See DTC INSPECTION .)
If servicing is performed after turning off (disabling) the pacemaker radio wave interference prevention function and the power saving function of the remote transmitter, turn on (enable) the functions.
