CHECK FOR DTC
DTC C1686 Driver Side Camera Video Sync Signal Malfunction
DTC C1687 Over Current Detected in Driver Side Camera
DESCRIPTION
DTC C1686 is stored if the parking assist ECU judges as a result of its self check that a synchronization problem is occurring in the image signal sent from the side television camera assembly (for Driver Side) to the parking assist ECU.
DTC C1687 is stored if the parking assist ECU judges as a result off its self check that there is a problem with the current supplied from the side television camera assembly (for Driver Side) connected to the parking assist ECU.

WIRING DIAGRAM
INSPECTION PROCEDURE
When "System initializing" is displayed on the parking assist ECU after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point ().
Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the side monitor system may be needed ().
| 1.CHECK HARNESS AND CONNECTOR (PARKING ASSIST ECU - OUTER REAR VIEW MIRROR ASSEMBLY AND BODY GROUND) |
Disconnect the F75 and F76 parking assist ECU connectors.
Disconnect the I35*1 or I32*2 outer rear view mirror assembly (for Driver Side) connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
- for LHD:
| Tester Connection | Condition | Specified Condition |
| F76-31 (DCV-) - I35-12 (DCV-) | Always | Below 1 Ω |
| F76-30 (DCV+) - I35-1 (DCV+) | Always | Below 1 Ω |
| F76-29 (DGND) - I35-13 (DGND) | Always | Below 1 Ω |
| F76-28 (DCB+) - I35-2 (DCB+) | Always | Below 1 Ω |
| F75-4 (GND1+) - Body ground | Always | Below 1 Ω |
| F76-31 (DCV-) - Body ground | Always | 10 kΩ or higher |
| F76-30 (DCV+) - Body ground | Always | 10 kΩ or higher |
| F76-29 (DGND) - Body ground | Always | 10 kΩ or higher |
| F76-28 (DCB+) - Body ground | Always | 10 kΩ or higher |
- for RHD:
| Tester Connection | Condition | Specified Condition |
| F76-31 (DCV-) - I32-12 (SCV-) | Always | Below 1 Ω |
| F76-30 (DCV+) - I32-1 (SCV+) | Always | Below 1 Ω |
| F76-29 (DGND) - I32-13 (SGND) | Always | Below 1 Ω |
| F76-28 (DCB+) - I32-2 (SCB+) | Always | Below 1 Ω |
| F75-4 (GND1+) - Body ground | Always | Below 1 Ω |
| F76-31 (DCV-) - Body ground | Always | 10 kΩ or higher |
| F76-30 (DCV+) - Body ground | Always | 10 kΩ or higher |
| F76-29 (DGND) - Body ground | Always | 10 kΩ or higher |
| F76-28 (DCB+) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 2.CHECK PARKING ASSIST ECU (DCB+, DGND) |
Reconnect the F75 and F76 parking assist ECU connectors.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| F76-29 (DGND) - Body ground | Always | Below 1 Ω |
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
| Tester Connection | Switch Condition | Specified Condition |
| F76-28 (DCB+) - F76-29 (DGND) | Engine switch on (IG), front and side monitor main switch assembly on | 5.5 to 7.05 V |

| | REPLACE PARKING ASSIST ECU ()
|
|
|
| 3.CHECK SIDE TELEVISION CAMERA ASSEMBLY (DCV+, DGND OR SCV+. SGND) |
Reconnect the I35*1 or I32*2 outer rear view mirror assembly (for Front Passenger Side) connector.
Text in Illustration| *a | Component with harness connected
(Parking Assist ECU) | *b | Waveform A |
| *c | Waveform B | *d | Synchronization Signal |
| *e | Video Waveform | - | - |
A waterproof connector is used for the side television camera assembly (for Driver Side). Therefore, inspect the waveform at the parking assist ECU with the connector connected.
The video waveform changes according to the image sent by the side television camera assembly (for Driver Side).
Measure the resistance according to the value(s) in the table below.
- OK:
- Waveform is as shown in the illustration.
| Item | Content |
| Terminal No. (Symbol) | F76-30 (DCV+) - F76-29 (DGND) |
| Tool Setting | 200 mV/DIV., 50 μsec./DIV. |
| Condition | Waveform A: Engine switch on (IG), front and side monitor main switch assembly on and camera lens is not covered, displaying an image
Waveform B: Engine switch on (IG), front and side monitor main switch assembly on and camera lens is covered, blacking out the screen
|
| OK | |
| |
| REPLACE PARKING ASSIST ECU ()
|
|
| 4.REPLACE SIDE TELEVISION CAMERA ASSEMBLY |
Replace the side television camera assembly (for Driver Side) with a new or normally functioning one ().
Check for DTCs ().
- OK:
- DTC C1686 or C1687 is not output.
| | REPLACE OUTER REAR VIEW MIRROR ASSEMBLY ()
|
|
|
| OK | |
| |
| END (DRIVER SIDE TELEVISION CAMERA ASSEMBLY IS DEFECTIVE) |
