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 "OFF".
- Perform "Oscilloscope" procedure in the "Diagnosis" with GDS.
- Measure the signal waveform between "LIN Communication" terminal of "DRIVER POWER OUTSIDE MIRROR_SMART CONNECTOR" harness connector and chassis ground.
■ Reference data
- Does the measured signal waveform follow the reference data?
YES
- Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage and 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.
