OK
2 PERFORM ACTIVE TEST USING HAND±HELD TESTER
(a) Select the ACTIVE TEST, use the hand±held tester to generate a control command and then check that the power door lock operates.
HINT:
During the ACTIVE TEST, the hand±held tester sends a signal to the body ECU to drive all th\
e power door
lock motors. If the power door lock operates, the power door lock motor itse\
lf and the wire harness between
the power door lock motor and body ECU are considered to be functioning nor\
mally. Standard (Multiplex network body ECU):
