3. CHECK POWER SUPPLY AND GROUND CIRCUIT
Step
1 CHECK POWER SUPPLY.
1) Disconnect the harness connector of body
integrated module.
2) Measure the voltage between harness con-
nector terminal and chassis ground.

4. CHECK DOOR LOCK SWITCH
Step
1 CHECK DOOR LOCK SWITCH.
Check the input from door lock switch to body
integrated module using Subaru Select Moni-
tor.
1) Connect the Subaru Select Monitor to data
link connector.
2) Turn the ignition switch to ON.
3) Select {Integ ⋅ unit} from main menu.
4) Select {Current Data Display & Save}.
5) Check the input to body integrated module
by operating the door lock switch.
2 CHECK DOOR LOCK SWITCH CIRCUIT.
