Signal Circuit Inspection
WARNING: This page is about a different car, the 2017 Genesis G80. However, it is still accessible from the selected car via links, so may be relevant.
- IG key "ON", Engine "ON".
- Set the shift lever in "D" range, move vehicle slowly to recognize the obstacles.
- Perform "Oscilloscope" procedure in the "Diagnosis" with GDS.
- Measure the signal waveform between "LIN LINE" terminal of "FRONT PARKING ASSIST SENSOR LH" harness connector and chassis ground.
■ Reference data
- Does the measured signal waveform follow the reference data?
YES
- Fault is intermittent caused by poor contact in "FRONT PARKING ASSIST SENSOR LH"'s connector.
- Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
- Repair or replace as necessary, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- If the voltage of measured signal waveform is the battery voltage level (about 12V),
→ Check LIN line short to battery.
→ Check LIN line open/poor connection.
- If the voltage of measured signal waveform is the ground voltage level (about 0V), check LIN line short to ground.
- If the signal waveform is abnormal, check for foreign substance around sensor, trapped sensor rubber.
