STEP 3. Voltage measure at camera-ECU connector (ACCN, ACCR, ACCS and ACCY terminals)
(1) Connect camera connectors one after the other, and then measure at the power supply terminal of the corresponding camera-ECU connector by backprobing.
(2) Turn the ignition switch to "ON" position.
(3) Connect the front-view camera connector.
(4) Check the voltage between camera-ECU connector (ACCN terminal) and ground.OK: 5.5 - 6.5 V
(5) Connect the rear-view camera connector.
(6) Check the voltage between camera-ECU connector (ACCR terminal) and ground.OK: 5.5 - 6.5 V
(7) Connect the side-view camera (LH) connector.
(8) Check the voltage between camera-ECU connector (ACCS terminal) and ground.OK: 5.5 - 6.5 V
(9) Connect the side-view camera (RH) connector.
(10) Check the voltage between camera-ECU connector (ACCY terminal) and ground.OK: 5.5 - 6.5 V
Is the check result normal?
Go to Step 4. Replace the failure camera (Refer to ).
