TIRE PRESSURE RECEIVER

TIRE PRESSURE RECEIVER

Description

INFOID:0000000000957904

The tire pressure receiver receives the air pressure signal transmitted by the transmitter in each wheel.

Diagnosis Procedure

INFOID:0000000000957905

1.

CHECK TIRE PRESSURE RECEIVER

1.

Turn ignition OFF.

2.

Check tire pressure receiver connector M101 terminal 2 and ground signal with oscilloscope.

Is the reference signal inputted?

YES

>> INSPECTION END

NO

>> GO TO 2.

2.

CHECK TIRE PRESSURE RECEIVER INPUT VOLTAGE

1.

Disconnect tire pressure receiver connector.

2.

Check voltage between tire pressure receiver connector M101 terminal 4 and ground.

Is the reference voltage inputted?

YES

>> GO TO 3.

NO

>> Check BCM harness and connector. 

3.

CHECK TIRE PRESSURE RECEIVER GROUND CIRCUIT

1.

Disconnect BCM harness connector and tire pressure receiver connector.

2.

Check continuity between BCM harness connector M123 terminal 137 and tire pressure receiver connec-
tor M101 terminal 1.

Also check harness for short to ground.

Is the inspection result normal?

TIRE PRESSURE WARNING CHECK SWITCH

TIRE PRESSURE WARNING CHECK SWITCH

Description

INFOID:0000000000957906

The following item can be checked by grounding the tire pressure warning check switch harness connector
terminal.
• The low tire pressure warning lamp in the combination meter will flicker according to the self-diagnostic

results.

NOTE:
If warning lamp blinks below, the system in normal.
• This mode shows transmitter status is in OFF-mode.

Perform transmitter wake up operation. Refer to 

WT-5, "TRANS-

MITTER WAKE UP OPERATION : Special Repair Requirement"

.

Diagnosis Procedure

INFOID:0000000000957907

1.

CHECK TIRE PRESSURE WARNING CHECK SWITCH CIRCUIT

1.

Turn ignition switch “OFF”.

2.

Disconnect BCM harness connector

3.

Check continuity between BCM harness connector M123 terminal 149 and ground.

Also check harness for short to ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace damaged parts.

2.

CHECK SYMPTOM

Check the low tire pressure warning lamp for blinking pattern.
Does the low tire pressure warning lamp remain blinking?

YES

>> GO TO 3.

NO

>> INSPECTION END

3.

CHECK BCM

Check BCM input/output signal. Refer to 

WT-43, "Reference Value"

.

Is the inspection result normal?

YES

>> GO TO 2.
