Self Diagnostic Procedure (Without Consult-III)

Turn ignition switch ON.
Ground the tire pressure warning check connector to initiate self diagnosis.

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".
