Result:
OK
Go to next step
- INSPECT RADIO AND DISPLAY RECEIVER ASSEMBLY
- Reconnect the F72 radio and display receiver assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition F72-24 (V-) - Body ground Always Below 1 Ω F72-23 (CGND) - Body ground Always Below 1 Ω *a Component with harness connected
(Radio and Display Receiver Assembly) - Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition F72-11 (CA+) - F72-23 (CGND) Power switch on (ACC) 5.5 to 7.05 V Proceed to OK NG
Result:
NG
REPLACE RADIO AND DISPLAY RECEIVER ASSEMBLY:
Refer to REMOVAL [02/2014 - ]
Result:
OK
Go to next step
- INSPECT TELEVISION CAMERA ASSEMBLY
- Reconnect the X13 television camera assembly connector.
- Using an oscilloscope, check the waveform of the television camera assembly.
HINT:
A waterproof connector is used for the 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.
Item Content Measurement terminal F72-12 (V+) - F69-7 (GND1) Measurement setting 200 mV/DIV., 50 μs./DIV. Condition Power switch on (IG), shift lever in R HINT:
- The video waveform changes according to the image sent by the television camera assembly.
- The video waveform is constantly output when the power switch is on (ACC).
