Before performing troubleshooting, inspect the connectors of related circuits.
Before replacing the suspension control ECU, perform all of the following again: 1) symptom simulation. Refer to ELECTRONIC CIRCUIT INSPECTION PROCEDURE ; 2) DTC inspection; and 3) the 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. Refer to INITIALIZATION .
The system may output DTC C1761 even when the system is normal if one of the following occurs: 1) the vehicle is full of passengers and the luggage compartment is full; 2) the vehicle is being driven or is stopped on an irregular surface; or 3) the air ducts are frozen.
