PROCEDURE
|
1. |
CHECK HARNESS AND CONNECTOR (TELEVISION CAMERA CONTROLLER - REAR TELEVISION CAMERA ASSEMBLY) |
(a) Disconnect the R42 television camera controller connector.
(b) Disconnect the m1 rear television camera assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
R42-1 (CV+) - m1-3 (CV+) |
Always |
Below 1 Ω |
|
R42-2 (CV-) - m1-2 (CV-) |
Always |
Below 1 Ω |
|
R42-9 (CGND) - m1-5 (CGND) |
Always |
Below 1 Ω |
|
R42-1 (CV+) or m1-3 (CV+) - Body ground |
Always |
10 kΩ or higher |
|
R42-2 (CV-) or m1-2 (CV-) - Body ground |
Always |
10 kΩ or higher |
|
R42-9 (CGND) or m1-5 (CGND) - Body ground |
Always |
10 kΩ or higher |
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
2. |
CHECK HARNESS AND CONNECTOR (ACC POWER SUPPLY - GROUND) |
(a) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
m1-6 (CB+) - Body ground |
Engine switch on (ACC) |
11 to 14 V |
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
3. |
CHECK TELEVISION CAMERA CONTROLLER (CV-, CGND) |
(a) Disconnect the R42 television camera controller connector.
|
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
| NG |
|
|
|
4. |
CHECK REAR TELEVISION CAMERA ASSEMBLY (CV+, CGND) |
(a) Remove the television camera controller with the connector still connected.
(b) Using an oscilloscope, check the waveform of the rear television camera assembly.
HINT:
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the television camera controller with the connector connected.

*e |
Video Waveform |
- |
- |
HINT:
- The video waveform changes according to the image sent by the rear television camera assembly.
- The video waveform is constantly output when the engine switch is on (ACC).
