LOW TIRE PRESSURE WARNING LAMP

Description

INFOID:0000000003412922

The combination meter receives tire pressure status from the BCM
via CAN communication.
When BCM judges from a transmitter signal that tire pressure is
insufficient, BCM transmits a signal to combination meter via CAN
communication. Combination meter turns on the low tire pressure
warning lamp mounted on the combination meter.

NOTE: Standard air pressure is for 230 kPa (2.3 kg/cm

2

, 33 psi) vehicles.

1.

CHECK LOW TIRE PRESSURE WARNING LAMP

Check if low tire pressure warning lamp blinks for 1 second and then goes off after turning the ignition switch
ON.

Is inspection result normal?

YES

>> INSPECTION END

NO

>> Proceed to diagnosis procedure. Refer to 

WT-41, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000003412924

1.

CHECK SELF DIAGNOSTIC RESULTS

Perform self-diagnosis of tire pressure monitoring system.
Is inspection result normal?

YES

>> GO TO 2.

NO

>> Check the DTC.

2.

CHECK LOW TIRE PRESSURE WARNING LAMP

Check if low tire pressure warning lamp blinks 1 second and then goes off after turning the ignition switch ON.
Is inspection result normal?

YES

>> INSPECTION END

NO

>> Check combination meter.
