Transmitter Wake Up Operation INFOID:0000000004307325
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.
3. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and sends flashing indicator status by CAN according to the following time chart.
4. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

1. Turn ignition switch ON.
2. Ground the tire pressure warning check connector to initiate self diagnosis.
3. Compare the flashing pattern with the flash code chart below.
NOTE:
The system is normal when the low tire pressure warni ng lamp flashes 5 times and continues repeating. Self-
diagnosis results are erased automatically by turning the ignition switch “OFF”.
