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

1. PARKING ASSIST ECU





(a) Disconnect the H9 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 H9 connector to the parking assist ECU.

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





If the result is not as specified, the parking assist 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.
