COMMENTS ON TROUBLE SYMPTOM
|
|
If only the reversing sensor OFF indicator lamp
does not illuminate, the wiring harness, connectors, corner sensor-ECU, or
combination meter may be defective.
|
|
- Damaged harness wires and connectors
- Malfunction of corner sensor-ECU
- Malfunction of the combination meter
|
|
STEP 1. Inspect the reversing sensor OFF indicator lamp with ignition
switch turned to "ON" position.
|
|
Verify that the reversing sensor OFF indicator
lamp will illuminate for 1 second when the ignition switch is turned to the
"ON" position.
|
|

|
|
|
Go to Step 2.
|
|
|
|
STEP 2. Connector check: D-16 corner sensor-ECU connector and D-04
combination meter.
|
|
Q.

|
|
Go to Step 3.
|
|
|
|
Repair
the defective connector.
|
|
|
|
STEP 3. Check the wiring harness between D-04 combination meter
connector terminal No. 8 and D-16 corner sensor-ECU connector terminal No.
12.

the wiring harness.
|
|
|
|
STEP 4. Connector check: D-02 combination meter
connector.
|
|
Q.

|
|
|
|
STEP 5. Voltage measurement at D-02 combination meter connector in
order to power supply circuit to combination meter (IG1 power
supply)
|
|
(1)Disconnect D-02 combination meter connector, and measure
at the wiring harness side.
|
|
(2)Turn the ignition switch to "ON" position.
|
|
(3)Measure the voltage between terminal No. 42 and
earth. OK: System voltage

|
Go to Step 7.
|
|
|
|
Go to Step 6.
|
|
|
|
STEP 6. Check the wiring harness between D-02 combination meter
connector terminal No. 42 and ignition switch (IG1).
|
|
note |
Before the wiring harness inspection, inspect
junction block connector D-405 and D-403, and repair if necessary.
|
|
|
Q.
Is the check result normal?
|
|
Go to step 7.
|
|
|
|

the wiring harness.
|
|
|
|
STEP 7. Verification after corner sensor-ECU replacement
|
|
After replacing the corner sensor-ECU, verify
that the reversing sensor OFF indicator lamp illuminates normally.
|
|
