Self-Diagnosis (Without CONSULT)

INFOID:0000000009483092

NOTE:

The Signal Tech II Tool (J-50190) can be used to perform the following functions. Refer to the Signal Tech II

User Guide for additional information.

• Activate and display TPMS transmitter IDs

• Display tire pressure reported by the TPMS transmitter

• Read TPMS DTCs

• Register TPMS transmitter IDs

SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT)

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.
