Diagnosis Procedure

INFOID:0000000005549606

1.

CHECK TIRE PRESSURE SIGNAL

With CONSULT-III

1.

Drive for 3 minutes at a speed of 40 km/h (25 MPH) or more, then drive normally for 10 minutes.

2.

Within 5 minutes, select “DATA MONITOR” of “AIR PRESSURE MONITOR”. 

3.

Read the values that are displayed for “AIR PRESS FL”, “AIR PRESS FR”, “AIR PRESS RR”, and “AIR
PRESS RL”.

CHECK RECEIVER CIRCUIT

1.

Turn the ignition switch OFF.

2.

Disconnect the low tire pressure warning control unit harness connector and tire pressure receiver har-
ness connector.

3.

Check the continuity between the harness connector terminals of the low tire pressure warning control
unit and tire pressure receiver.
