Turn the ignition switch to ON. Select {Integ. unit} from main menu. Select the {Current Data Display & Save}. Check the input signal to body integrated unit by operating the door lock switch.	Is the normal input signal displayed 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. Disconnect the harness connector of body integrated unit. Measure the resistance between the harness connector terminal and chassis ground when moving the door lock switch to LOCK. Connector & terminal (i84) No. 15 - Chassis ground:	Is the resistance less than 10 Ω?	Go to step 3.	Go to step 4.
3 CHECK DOOR LOCK SWITCH CIRCUIT. Measure the resistance between the harness connector terminal and chassis ground when the door lock switch is moved to UNLOCK. Connector & terminal (i84) No. 29 - Chassis ground:	Is the resistance less than 10 Ω?	The door lock switch is OK.	Go to step 4.
4 CHECK DOOR LOCK SWITCH. Disconnect the door lock switch harness connector. Measure the resistance between the door lock switch terminals when moving the door lock switch to LOCK. Connector & terminal Driver's side: (D7) No. 4 - No. 7: Passenger's side: (D125) No. 4 - No. 3:	Is the resistance less than 1 Ω?	Go to step 5.	Replace the door lock switch.

Connector & terminal Driver's side: (D7) No.5 - No. 7: Passenger's side: (D125) No. 1 - No. 3:	Is the resistance less than 1 Ω?	Check the harness for open circuits or shorts between the body integrated unit and the door lock switch.	Replace the door lock switch.
