Diagnosis System

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: DIAGNOSIS SYSTEM

1. DIAGNOSIS SYSTEM

(a) Warning light and indicator

(1) When there is a problem with the tire pressure warning system, the tire pressure warning light blinks at 0.5 second intervals, and illuminates after 1 minute.

NOTICE:
When the malfunction has been corrected, the tire pressure warning light does not illuminate or blink.

(b) DTCs (Normal mode)

(1) DTCs are memorized in the tire pressure warning ECU and read by the blinks of the tire pressure warning light or by using the Techstream Reading and Clearing Diagnostic Trouble Codes.

(c) Test mode

(1) By switching from normal mode into test mode (input signal check), you can inspect the tire pressure warning antenna and receiver, each tire pressure warning valve and transmitter, engine speed signal and vehicle speed sensor Test Mode Procedure.

2. CHECK WARNING LIGHT

(a) Turn the ignition switch to ON.

(b) Check that the tire pressure warning light illuminates for 3 seconds.

If the warning check result is not normal, proceed to the troubleshooting for the tire pressure warning light circuit.
