REAR TELEVISION CAMERA ASSEMBLY
Disconnect the V13 rear television camera assembly connector.
Measure the voltage on the wire harness side connector according to the value(s) in the table below.
| Terminal No. (Symbol) | Wiring Color | Terminal Description | Condition | Specified Condition |
|---|---|---|---|---|
| V13-6 (CB+) - Body ground | B - Body ground | Power source | Power switch on (ACC) | 5.5 to 7.05 V |
If the result is not as specified, there may be a malfunction on the wire harness side.
Reconnect the V13 rear television camera assembly connector.
Check for pulses between each terminal of the connector.
| Terminal No. (Symbol) | Wiring Color | Terminal Description | Condition | Specified Condition |
|---|---|---|---|---|
| V13-3 (CV+) - V13-2 (CV-) | R - W | Video signal |

Waveform 1 (camera lens is not covered, displaying an image)
| Item | Content |
|---|---|
| Measurement terminal | V13-3 (CV+) - V13-2 (CV-) |
| Measurement setting | 200 mV/DIV., 50 μs./DIV. |
| Condition | Power switch on (IG), reverse (R) selected |
Tech Tips
The video waveform changes according to the image sent by the rear television camera assembly.
The video waveform is constantly output when the power switch is on (ACC).
Waveform 2 (camera lens is covered, blacking out the screen)
| Item | Content |
|---|---|
| Measurement terminal | V13-3 (CV+) - V13-2 (CV-) |
| Measurement setting | 200 mV/DIV., 50 μs./DIV. |
| Condition | Power switch on (IG), reverse (R) selected |
