Advanced Parking Guidance System

PARK ASSIST / MONITORING: ADVANCED PARKING GUIDANCE SYSTEM: TERMINALS OF ECU

1. PARKING ASSIST ECU





(a) Disconnect the L64 connector from the parking assist ECU.

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





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

(c) Reconnect the L64 connector to the ECU.

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





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

*1: for LED headlight

*2: for Halogen headlight

(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 (camera lens is not covered, displaying an image)





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 V6 connector from the rear television camera assembly.

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





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

(c) Reconnect the V6 connector to the rear television camera assembly.

(d) Check for pulses according to the value(s) in the table below.
