If either reversing sensor (corner sensor/back sensor) do not detect the obstacle, the wiring harness, connectors, each sensor or corner sensor/back sensor-ECU may be defective. In addition, obstacle is not detected when the ultrasonic noise is received.

- Damaged harness wires and connectors
- Malfunction of reversing sensor (corner sensor/back sensor)
- Malfunction of corner sensor/back sensor-ECU

Q.
Are there anything that interferes with the communication (things that generate radio waves such as magnets and an air-cleaning device that has a power plug) near the corner sensor/back sensor?
|
|
Move away or remove things that interfere with the communication (things that generate radio waves such as magnets and a air-cleaning device that has a power plug) near the corner sensor/back sensor.

Q.
Which reversing sensor (corner sensor/back sensor) does not detect the obstacle?
|
|
Corner sensor (rear: RH) : Go to Step 3.
|
|
|
|
Corner sensor (rear: LH) : Go to Step 6.
|
|
|
|
Back sensor (RH) : Go to Step 9.
|
|
|
|
Back sensor (LH) : Go to Step 12.
