INSPECTION PROCEDURE

NOTE:
- Before performing troubleshooting, inspect the connectors of related circuits.
- If DTC C1782/82 (Power Source Voltage Malfunction) is output at the same time, perform troubleshooting for C1782/82 first.
- Before replacing the suspension control ECU, perform all of the following again: 1) symptom simulation; 2) DTC inspection; and 3) intelligent tester or Techstream inspection (Data List or Active Test). If no malfunctions are found in other areas, replace the suspension control ECU.
- If the suspension control ECU or height control sensor is replaced, the vehicle height offset calibration must be performed.
