TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: DIAGNOSIS SYSTEM

1. CHECK DLC3

(a) Check the DLC3 General Information.

2. 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 turns on after 1 minute

HINT
When the malfunction has been corrected, the tire pressure warning light does not turn on.

(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 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, and vehicle speed sensor Test Mode Procedure.

3. CHECK TIRE PRESSURE WARNING LIGHT

(a) Turn the ignition switch on (IG).





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

If the warning check result is not normal, proceed to the troubleshooting for the tire pressure warning light circuit Tire Pressure Warning Light Circuit.
