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
