INSPECTION PROCEDURE

HINT:
Set the tire pressure to the specified value.

1.INSPECT TIRE PRESSURE MONITOR RECEIVER ASSEMBLY


    C111008E01

  1. Disconnect the tire pressure monitor receiver assembly W34 connector.

  1. Measure the voltage according to the value(s) in the table below.

    Standard voltage:
    Tester Connection
    		Specified Condition
    W34-4 (GND) - W34-5 (+5V)
    		4.5 to 5.5 V



NG
Go to step 3
OK


2.CHECK HARNESS AND CONNECTOR (TIRE MONITOR RECEIVER ASSEMBLY-TIRE MONITOR ECU)


    C107245E06

  1. Disconnect the tire pressure monitor receiver assembly W34 connector and tire pressure monitor ECU K45 connector.



    C110641E01

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Specified Condition
    K45-9 (RDA) - W34-1 (RDA)
    		Below 1 Ω



OK
Go to step 5
NG


3.CHECK HARNESS AND CONNECTOR (TIRE MONITOR RECEIVER ASSEMBLY-TIRE MONITOR ECU)
C107245E07

  1. Disconnect the tire pressure monitor receiver assembly connector and tire pressure monitor ECU K45 connector.



    C107249E01

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    		Specified Condition
    K45-9 (RDA) - W34-1 (RDA)
    		Below 1 Ω
    K45-10 (RF5V) - W34-5 (+5V)
    		Below 1 Ω
    K45-4 (GND2) - W34-4 (GND)
    		Below 1 Ω
    K45-9 (RDA) - Body ground
    		10 kΩ or higher
    K45-10 (RF5V) - Body ground
    		10 kΩ or higher
    K45-4 (GND2) - Body ground
    		10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


4.CHECK POWER SOURCE CIRCUIT


NG
REPAIR OR REPLACE POWER SOURCE CIRCUIT
OK


5.REPLACE TIRE PRESSURE MONITOR RECEIVER ASSEMBLY

HINT:
Perform the inspection using parts from a normal vehicle possible.


NEXT


6.CHECK DTC

  1. Check for DTC.

    OK:
    DTC is not output.

    HINT:
    1. It is necessary to register an ID when replacing the tire pressure monitor ECU.
    2. Read ID on the DATA LIST before removing the tire pressure monitor ECU. Register the ID in the new tire pressure monitor ECU (Click here).



NG
REPLACE TIRE PRESSURE MONITOR ECU
OK
