TIRE PRESSURE SENSOR ID REGISTRATION
Description
INFOID:0000000010120187
This procedure must be done after replacing tire pressure sensor or BCM.
Work Procedure
INFOID:0000000010120188
TPMS ID registration can be performed using one of the following procedures:
• Transmitter Activation tool [KV48105501 (J-45295-A)] with CONSULT (preferred method)
• Signal Tech II tool [- (J-50190)] with CONSULT (preferred method)
• Signal Tech II tool [- (J-50190)] without CONSULT
• CONSULT only
TPMS REGISTRATION WITH TRANSMITTER ACTIVATION TOOL [KV48105501 (J-45295-A)]
With CONSULT
1. Turn the ignition switch ON.
2. Using CONSULT, select “Work support” of “BCM“. Then, select “ID REGIST.”
3. Select “Start” on “ID REGIST” screen.
4. Hold the transmitter activation tool [KV48105501 (J-45295-A)]
(1) against the side of the left front tire, near the valve stem.
5. With the tool held at a 0 to 15 degree angle to the tire, press and
hold the transmitter activation tool button until the indicator lamp
turns OFF (approximately 5 seconds).
6. Repeat steps 4 and 5 for the remaining tires in this order: right
front, right rear and left rear.
7. When ID registration is complete, check the following pattern at each wheel.
8. After the ID registration procedure for all wheels is complete, press “End” on the CONSULT to finish ID
registration.
9. Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
TPMS REGISTRATION WITH SIGNAL TECH II TOOL [- (J-50190)]
NOTE:
The Signal Tech II must be updated with the newest software version in order to perform the below proce-
dures. The Signal Tech II software updates can only be downloaded from a CONSULT unit with ASIST. Other
versions of ASIST will not show the updates.
With CONSULT
1. Adjust the tire pressure for all tires to the recommended value. Refer to
2. Turn the ignition switch ON.

6. Hold the Signal Tech II against the side of the left front tire, near
the valve stem.
7. With the tool held at a 0 to 15 degree angle to the tire, select
“Activate Sensor” from the main menu, then press and release
the “OK” button to activate the sensor. Once the sensor is acti-
vated, the vehicle parking lamps will flash and the sensor ID will

is activated, the tool will sound a tone and the tire pressure will
be displayed.
6. Repeat steps 4 and 5 for the remaining tires in this order: right
front, right rear and left rear.
7. When prompted, connect the tool to the data link connector. The
tool will connect to the BCM, read the VIN, read sensor IDs and
check for TPMS DTCs. Along with DTCs detected, one of the
following will be displayed next to each wheel:
-
N/A - Not applicable because no ID found by the tool
-
OK - Wheel and sensor are in original position
-
NEW - New ID found compared to BCM
-
RT - Wheel has been rotated
-
Low Press - Low tire pressure
8. If no DTC is present or the repair has been completed, press the “OK” button to register the IDs and clear
DTCs.
9. Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
10. Print a Signal Tech II Audit Report for your records. Refer to the Signal Tech II User Guide for instructions.
