- *1: for Hatchback Model
- *2: for Sedan Model
(b) Using an oscilloscope, check the waveform of the rear television camera 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.
