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”.
