3. |
INSPECT REAR TELEVISION CAMERA ASSEMBLY |
(a) Reconnect the Y2 rear television camera assembly connector.
(b) Check the waveform of the rear television camera assembly using an oscilloscope.
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.
