PROCEDURE
1. | CHECK DTC |
(a) Clear the DTCs.
Body Electrical > Navigation System > Clear DTCs(b) Turn the engine switch off.
(c) Turn the engine switch on (IG).
(d) Change the shift position to R and check for DTCs.
Body Electrical > Navigation System > Trouble CodesOK:
No DTCs are output.
OK | ![]() | USE SIMULATION METHOD TO CHECK |
|
2. | CHECK HARNESS AND CONNECTOR (REAR TELEVISION CAMERA ASSEMBLY - MULTI-DISPLAY ASSEMBLY) |
(a) Disconnect the J56 multi-display assembly connector.
(b) Disconnect the z11 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 |
---|---|---|
J56-10 (CA+) - z11-6 (CB+) | Always | Below 1 Ω |
J56-8 (V+) - z11-3 (CV+) | Always | Below 1 Ω |
J56-9 (V-) - z11-2 (CV-) | Always | Below 1 Ω |
J56-21 (CGND) - z11-5 (CGND) | Always | Below 1 Ω |
J56-10 (CA+) or z11-6 (CB+) - Body ground | Always | 10 kΩ or higher |
J56-8 (V+) or z11-3 (CV+) - Body ground | Always | 10 kΩ or higher |
J56-9 (V-) or z11-2 (CV-) - Body ground | Always | 10 kΩ or higher |
J56-21 (CGND) or z11-5 (CGND) - Body ground | Always | 10 kΩ or higher |
J56-20 (CSLD) - Body ground | Always | 10 kΩ or higher |

3. | INSPECT MULTI-DISPLAY ASSEMBLY |
(a) Reconnect the J56 multi-display assembly connector.
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
J56-10 (CA+) - J56-21 (CGND) | Engine switch on (ACC) | 5.5 to 7.05 V |
NG | ![]() | REPLACE MULTI-DISPLAY ASSEMBLY |
|
4. | INSPECT MULTI-DISPLAY ASSEMBLY |
(a) Reconnect the z11 rear television camera assembly connector.
(b) Using an oscilloscope, check the waveform of the rear television camera assembly.
*a | Component with harness connected (Multi-display Assembly) |
HINT:
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the multi-display assembly with the connector connected.
OK:
Waveform is similar to that shown in the illustration.
Item | Content |
Measurement terminal | J56-8 (V+) - J56-13 (GND1) |
Measurement setting | 200 mV/DIV., 50 μs./DIV. |
Condition | Engine switch on (IG), shift lever in R |
HINT:
*a | Waveform 1 (camera lens is not covered, displaying an image) |
*b | Waveform 2 (camera lens is covered, blacking out the screen) |
*c | Synchronization Signal |
*d | Video Waveform |
NG | ![]() | REPLACE REAR TELEVISION CAMERA ASSEMBLY |
|
5. | REPLACE MULTI-DISPLAY ASSEMBLY |
(a) Replace the multi-display assembly with a new or known good one.
