COMMENTS ON TROUBLE SYMPTOM |
If either reversing sensor (corner sensor/back
sensor) does not detect the obstacle, the wiring harness, connectors, each
sensor or corner sensor-ECU may be defective. In addition, obstacle is not
detected when the ultrasonic noise is received. |
PROBABLE CAUSES |
|
DIAGNOSIS PROCEDURE |
STEP 1. Check the reversing sensor (corner sensor/back sensor) for interference. |
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 reversing sensor (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 reversing sensor (corner sensor/back sensor). |
|
Go to Step 2. |
|
STEP 2. Confirm which reversing sensor (corner sensor/back sensor) does not detect the obstacle. |
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. |
|
STEP 3. Connector check: D-16 corner sensor-ECU connector and E-110-1 corner sensor (rear: RH) connector. |
Q.
Is the check result normal?
|
Go to Step 4. |
|
Repair
the defective connector. |
|
STEP 4. Check the wiring harness between E-110-1 corner sensor (rear: RH) connector terminal No. 1, 2 and D-16 corner sensor-ECU connector terminal No. 8, 10. |
|
Q.
Is the check result normal?
|
Go to Step 5. |
|
Repair
the wiring harness. |
|
STEP 5. Verification after corner sensor replacement |
After replacing the corner sensor (rear: RH),
verify that the reversing sensor system is normally. |
Q.
Is the check result normal?
|
The
procedure is complete. |
|
Replace the corner
sensor-ECU. |
|
STEP 6. Connector check: D-16 corner sensor-ECU connector and E-113-1 corner sensor (rear: LH) connector. |
Q.
Is the check result normal?
|
Go to Step 7. |
|
Repair
the defective connector. |
|
STEP 7. Check the wiring harness between E-113-1 corner sensor (rear: LH) connector terminal No. 1, 2 and D-16 corner sensor-ECU connector terminal No. 7, 10. |
|
Q.
Is the check result normal?
|
Go to Step 8. |
|
Repair
the wiring harness. |
|
STEP 8. Verification after corner sensor replacement |
After replacing the corner sensor (rear: LH),
verify that the reversing sensor system is normally. |
Q.
Is the check result normal?
|
The
procedure is complete. |
|
Replace the corner
sensor-ECU. |
|
STEP 9. Connector check: D-16 corner sensor-ECU connector and G-08 back sensor (RH) connector. |
Q.
Is the check result normal?
|
Go to Step 10. |
|
Repair
the defective connector. |
|
STEP 10. Check the wiring harness between G-08 back sensor (RH) connector terminal No. 1, 2 and D-16 corner sensor-ECU connector terminal No. 9, 10. |
|
Q.
Is the check result normal?
|
Go to Step 11. |
|
Repair
the wiring harness. |
|
STEP 11. Verification after back sensor replacement |
After replacing the back sensor (RH), verify
that the reversing sensor system is normally. |
Q.
Is the check result normal?
|
The
procedure is complete. |
|
Replace the corner
sensor-ECU. |
|
STEP 12. Connector check: D-16 corner sensor-ECU connector and G-11 back sensor (LH) connector. |
Q.
Is the check result normal?
|
Go to Step 13. |
|
Repair
the defective connector. |
|
STEP 13. Check the wiring harness between G-11 back sensor (LH) connector terminal No. 1, 2 and D-16 corner sensor-ECU connector terminal No. 6, 10. |
|
Q.
Is the check result normal?
|
Go to Step 14. |
|
Repair
the wiring harness. |
|
STEP 14. Verification after back sensor replacement |
After replacing the back sensor (LH), verify
that the reversing sensor system is normally. |
Q.
Is the check result normal?
|
The
procedure is complete. |
|
Replace the corner
sensor-ECU. |
