Parking Assist Monitor System

PARK ASSIST / MONITORING: PARKING ASSIST MONITOR SYSTEM: TERMINALS OF ECU

1. REAR TELEVISION CAMERA ASSEMBLY

(a) Disconnect the T6 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) Measure the resistance according to the value(s) in the table below.

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

(d) Reconnect the T6 connector to the rear television camera assembly.

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

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

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

(f) Reference (Oscilloscope waveform):

HINT
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the navigation ECU sub-assembly 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. INSTRUMENT PANEL JUNCTION BLOCK ASSEMBLY AND MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU)

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

If the result is not as specified, the main body ECU (multiplex network body ECU) or instrument panel junction block assembly may have a malfunction.

3. NAVIGATION ECU SUB-ASSEMBLY (for Radio and Display Type with Intuitive Parking Assist System) Audio And Visual System (with Intuitive Parking Assist System)
