Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 3
- CHECK PARKING ASSIST ECU (RCV-, RGND)
- Disconnect the G95 parking assist ECU connector.
*a Component without harness connected
(Parking Assist ECU) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 17 (RGND) - Body ground Always Below 1 Ω 16 (RCV-) - Body ground Always Below 1 Ω Result
Proceed to OK NG
Result:
NG
REPLACE PARKING ASSIST ECU. Refer to REMOVAL [10/2017 - 10/2020]
Result:
OK
See step 4
- Disconnect the G95 parking assist ECU connector.
- CHECK PARKING ASSIST ECU (RCB+, RGND)
- Remove the parking assist ECU with the connector still connected.
*a Component with harness connected
(Parking Assist ECU) - Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Switch Condition Specified Condition G95-40 (RCB+) - G95-17 (RGND) Power switch on (IG) 5.5 to 7.05 V G95-40 (RCB+) - G95-17 (RGND) Power switch off Below 1 V - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition G95-17 (RGND) - Body ground Always Below 1 Ω Result
Proceed to OK NG
Result:
NG
REPLACE PARKING ASSIST ECU. Refer to REMOVAL [10/2017 - 10/2020]
Result:
OK
See step 5
- Remove the parking assist ECU with the connector still connected.
- CHECK SIDE TELEVISION CAMERA ASSEMBLY RH (RCV+, RGND)
- Remove the parking assist ECU with the connector still connected.
- Using an oscilloscope, check the waveform of the side television camera assembly RH.
HINT:
A waterproof connector is used for the side television camera assembly RH. Therefore, inspect the waveform at the parking assist ECU with the connector connected.
*a Component with harness connected
(Parking Assist ECU)*b Waveform 1 (camera lens not covered, displaying an image) *c Waveform 2 (camera lens covered, blacking out the screen) *d Synchronization Signal *e Video Waveform - - HINT:
- The video waveform changes according to the image sent by the side television camera assembly RH.
- The video waveform is constantly output when the power switch is on (ACC).
MEASUREMENT CONDITIONItem Content Tester Connection G95-38 (RCV+) - G95-17 (RGND) Tool Setting 200 mV/DIV., 50 μsec./DIV. Condition Power switch on (IG), panoramic view monitor switch on OK
Waveform is similar to that shown in illustration.
Result
Proceed to OK NG
Result:
OK
REPLACE PARKING ASSIST ECU. Refer to REMOVAL [10/2017 - 10/2020]
Result:
NG
See step 6
- INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH
- Disconnect the outer rear view mirror assembly RH connector.
*a Component without harness connected
(to Side Television Camera Assembly RH)*b Component without harness connected
(to Outer Rear View Mirror Assembly RH) - Disconnect the side television camera assembly RH connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition B-1 (SCB+) - 2 (RCB+) Always Below 1 Ω B-3 (SCV+) - 7 (RCV+) Always Below 1 Ω B-7 (SCV-) - 6 (RCV-) Always Below 1 Ω B-5 (SGND) - 1 (RGND) Always Below 1 Ω B-4 (SGND) - 3 (SGND) Always Below 1 Ω B-1 (SCB+) or 2 (RCB+) - Body ground Always 10 kΩ or higher B-3 (SCV+) or 7 (RCV+) - Body ground Always 10 kΩ or higher B-7 (SCV-) or 6 (RCV-) - Body ground Always 10 kΩ or higher B-5 (SGND) or 1 (RGND) - Body ground Always 10 kΩ or higher B-4 (SGND) or 3 (SGND) - Body ground Always 10 kΩ or higher Result
