Signal Circuit Inspection
- 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.
