PROCEDURE
|
1. |
CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - REAR TELEVISION CAMERA ASSEMBLY) |
(a) Disconnect the K2 radio and display receiver assembly 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 |
|---|---|---|
|
K2-28 (V+) - m1-3 (CV+) |
Always |
Below 1 Ω |
|
K2-29 (V-) - m1-2 (CV-) |
Always |
Below 1 Ω |
|
K2-27 (CGND) - m1-5 (CGND) |
Always |
Below 1 Ω |
|
K2-28 (V+) or m1-3 (CV+) - Body ground |
Always |
10 kΩ or higher |
|
K2-29 (V-) or m1-2 (CV-) - Body ground |
Always |
10 kΩ or higher |
|
K2-27 (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 |
Power switch on (ACC) |
11 to 14 V |
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
3. |
INSPECT RADIO AND DISPLAY RECEIVER ASSEMBLY (V-, CGND) |
(a) Reconnect the K2 radio and display receiver assembly connector.
|
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
| NG |
|
REPLACE RADIO AND DISPLAY RECEIVER ASSEMBLY
|
|
|
4. |
INSPECT RADIO AND DISPLAY RECEIVER ASSEMBLY (V+, GND1) |
(a) Reconnect the m1 rear television camera assembly connector.
(b) Using an oscilloscope, check the waveform of the rear television camera assembly.
|
*a |
Component with harness connected (Radio and Display Receiver Assembly) |
HINT:
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the radio and display receiver assembly with the connector connected.
OK:
Waveform is similar to that shown in the illustration.
