Sensor ID Registration Using Signal Tech II (Without CONSULT)

NOTE: The Signal Tech II must be updated with software version 1.1.48 or newer in order to perform the below procedures. 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.

Adjust the tire pressure for all tires to the recommended value.
Turn on the Signal Tech II and select TPMS CHECK from the main menu.
Select vehicle model and year.
When prompted, hold the Signal Tech II against the side of the left front tire, near the valve stem. See Figure.
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 activated, the vehicle parking lamps will flash and the sensor ID will appear on the CONSULT screen.
Repeat tool procedure for the remaining tires in this order: Right Front, Right Rear And Left Rear.
When prompted, connect the tool to the data link connector. The tool will connect to the low tire pressure warning control unit, 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 low tire pressure warning control unit
- RT - Wheel has been rotated
- Low Press - Low tire pressure
If no DTC is present or the repair has been completed, press the OK button to register the IDs and clear DTCs.
Test drive the vehicle to ensure that the TPMS lamp is OFF and no warning messages are present.
