INSPECTION PROCEDURE
1 INSPECT FUSE (ECU-B)
Standard resistance: Below 1 Ω
2 PERFORM ACTIVE TEST BY INTELLIGENT TESTER
HINT: During the ACTIVE TEST, the intelligent tester sends a signal to the body ECU to drive all the power door lock motors. If the power door lock operates, the power door lock motor itself and the wire harness between the power door lock motor and body ECU are considered to be functioning normally.
BODY (Multiplex network body ECU)
3 CHECK OPERATION (MASTER SWITCH OR KEY CYLINDER)
