PARK ASSIST / MONITORING: REAR VIEW MONITOR SYSTEM (w/ Side Monitor System): TERMINALS OF ECU

1. PARKING ASSIST ECU





(a) Disconnect the F54 connector from the ECU.

(b) Measure the voltage and resistance of each terminal of the wire harness side connector.





(b) If the result is not as specified, there may be a malfunction on the wire harness side.

(c) Reconnect the F54 connector to the ECU.

(d) Measure the voltage and check for pulses according to the value(s) in the table below.





(d) If the result is not as specified, the ECU may have a malfunction.

(e) Reference (Oscilloscope waveform):





HINT
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the parking assist ECU with the connector connected.

(1) Waveform 1 (under normal conditions)





HINT
The video waveform changes according to the image sent by the rear television camera assembly.

(2) Waveform 2 (camera lens is covered, blacking out the screen)





HINT
The video waveform changes according to the image sent by the rear television camera assembly.

2. REAR TELEVISION CAMERA ASSEMBLY

(a) Disconnect the Y14 connector from the rear television camera assembly.





(b) Measure the voltage of each terminal of the wire harness side connector.





(b) If the result is not as specified, there may be a malfunction on the wire harness side.

(c) Reconnect the Y14 connector to the rear television camera assembly.

(d) Check for pulses between each terminal of the connector.
