Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The diagnostic trouble code (DTC) is stored if the suspension module (SUM) registers that the voltage to any of the solenoids is too low. The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.
- SUM-0111: Solenoid, left front
- SUM-0121: Solenoid, right front
- SUM-0131: Solenoid, left rear
- SUM-0141: Solenoid, right rear.

Note! The test is carried out every other operating cycle. The Suspension module (SUM) defines an operating cycle as ignition on and ignition off.

Substitute value
- The Four-C (Continuously Controlled Chassis Concept) function is blocked.

Hint: For information about abbreviations for the suspension system, see Suspension system, abbreviations Description and Operation.

Possible source
- Contact resistance in the terminals
- Short-circuit to ground in the power supply to the solenoid
- Damaged solenoid.

Fault symptom[s]
- General warning lamp lit
- Message in the display
- Four-C (Continuously Controlled Chassis Concept) does not work.
