DIAGNOSTIC TROUBLE CODE CHART
HINT:
- Inspect the fuse before inspecting the suspected areas as shown in the chart.
- If no abnormality is found when the parts are inspected, inspect the suspension control ECU.
- If a trouble code is displayed during the DTC check, check the circuit listed for that code.
HINT:
*1: For codes marked with a 0 in the Manual Indicator Light column, the height control manual indicator light blinks at 1 second intervals.
*2: The codes marked with a 0 in the Memory column are stored in the memory even when the ignition switch is OFF, but the codes marked with X are not.
*3: The relief pressure of the compressed air is 980 kPa (10 kgf/cm2, 142 psi). DTC C1751/51 may be output and vehicle height control may be suspended under the following conditions (not abnormal):
- Vehicle height control is attempted on a steep slope when the vehicle is overloaded.
- The compressor remains on for an excessive period of time or repeatedly turns on and off because of continuous height control switch operation.
- The vehicle height control function (UP) operates when the vehicle height is set at a position lower than normal while the engine is running.
HINT:

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
