Intuitive Parking Assist System

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

1. CHECK CLEARANCE WARNING ECU (w/o Advanced Parking Guidance System)





(a) Disconnect the L19 ECU connector.

(b) Measure the voltage and resistance according to value(s) in the table below.





(c) Reconnect the L19 ECU connector.

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





(e) Using an oscilloscope, check waveform 1.









(f) Using an oscilloscope, check waveform 2.









NOTICE:
* The waveforms of CBZ and EE are offset by a half cycle. EF is not synchronized with CBZ and EE.
* The waveform's amplitude varies depending on the volume setting.
