Wide View Front Monitor System

PARK ASSIST / MONITORING: WIDE VIEW FRONT MONITOR SYSTEM: TERMINALS OF ECU

1. PARKING ASSIST ECU





(a) Disconnect the F36 connector from the ECU.

(b) Measure the resistance and 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 F36 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 front television camera assembly. Therefore, inspect the waveform at the parking assist ECU with the connector connected.

(1) Waveform 1 (under normal conditions) Reference





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

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





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





2. FRONT TELEVISION CAMERA ASSEMBLY

(a) Disconnect the connector from the front 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 connector to the front television camera assembly.

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





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

If the result is not as specified, the camera may have a malfunction.
