4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

ID Registration Procedure

INFOID:0000000005148205

ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL

NOTE:

This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.

New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter

Activation Tool J-45295 before ID registration can be performed.
1. Connect CONSULT-III.
2. Select "ID REGIST" under BCM.
3. Push the transmitter activation tool against the tire near the front

left transmitter. Press the button for 5 seconds.

been completed, the hazard warning lamps flash.

5. After completing all ID registrations, press “END” to complete the procedure.
NOTE:

Be sure to register all of the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results

display will not function properly.
