Low tire pres-
sure warning
lamp

The low tire pres-

LOW TIRE PRESSURE WARNING LAMP DOES NOT TURN ON

LOW TIRE PRESSURE WARNING LAMP DOES NOT TURN ON

Description

INFOID:0000000010120199

The low tire pressure warning lamp does not illuminate when the power switch is turned ON.

NOTE:

The low tire pressure warning lamp illuminates for approximately 1 second and then turns OFF when the

power switch is turned ON. This is to check that no abnormal condition is present in the tire pressure monitor-

ing system.

The lamp bulb may be burnt out or the tire pressure monitoring system may be malfunctioning if the low tire

pressure warning lamp does not illuminate when the power switch is turned ON.

Diagnosis Procedure

INFOID:0000000010120200

1.

CHECK LOW TIRE PRESSURE WARNING LAMP SIGNAL

With CONSULT

1. Turn the power switch ON.

CAUTION:

Never set the vehicle to READY.

2. Select “Active Test” in “AIR PRESSURE MONITOR” of “BCM”.

3. Touch “WARNING LAMP” to turn ON the low tire pressure warning lamp.
When “Active Test” is performed, does the low tire pressure warning lamp in the combination meter turn ON?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

CHECK LOW TIRE PRESSURE WARNING LAMP OPERATION

Check that when the power switch is turned ON, the low tire pressure warning lamp illuminates for approxi-

mately 1 second then turns OFF.
Is the inspection result normal?

YES

>> Check intermittent incident. Refer to

GI-53, "Intermittent Incident"

.

NO

>> Replace the BCM. Refer to

BCS-72, "Removal and Installation"

.

3.

CHECK COMBINATION METER POWER SUPPLY CIRCUIT

Perform the diagnosis for combination meter power supply circuit. Refer to

MWI-85, "COMBINATION METER

: Diagnosis Procedure"
