NOTE:
Before performing the self-diagnosis, be sure to register the ID or else the actual malfunction location may be different from that dis-
played on CONSULT.
Self-Diagnosis (Without CONSULT)
INFOID:0000000009885659
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.
NOTE:
The system is normal when the low tire pressure warning lamp flashes 5 times and continues repeating. Self-
diagnosis results are erased automatically by turning the ignition switch “OFF”.
