5) Check the input signal to body integrated
module by operating the door lock switch.

Is the normal input signal dis-
played when the door lock
switch is moved to LOCK/
UNLOCK?

The door lock
switch is OK.

Go to step 2.

2

CHECK DOOR LOCK SWITCH CIRCUIT.
1) Disconnect the body integrated module
harness connector.
