Diagnostic trouble code (DTC) information

Condition




The Suspension Module (SUM) receives information from the solenoids on each suspension unit. Diagnostic trouble code (DTC) SUM-0115, SUM-00125, SUM-0135 or SUM-0145 is stored if the control module registers that the current from one of the solenoids is too low when the ignition is switched on.
- SUM-0115: Solenoid, left front
- SUM-0125: Solenoid, right front
- SUM-0135: Solenoid, left rear
- SUM-0145: 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 function is blocked.

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