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-III.
Self-Diagnosis (Without CONSULT-III)INFOID:0000000005148233
SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III)
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”.
