Transmitter Wake Up OperationINFOID:0000000003532698
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. Turn ignition switch ON. Push the transmitter activation tool
against the tire near the front left transmitter. Press the button for
5 seconds. The hazard warning lamps flash per the diagram
below.
2. Repeat this procedure for each tire in the following order: FL, FR, RR, RL.
