Diagnostic trouble code (DTC) information

Condition




The Suspension Module (SUM) receives information from the solenoids on each suspension unit. Diagnostic trouble code (DTC) SUM-0117, SUM-00127, SUM-0137 or SUM-0147 is stored if the control module registers that the current from one of the solenoids is too high when the ignition is switched on.
- SUM-0117: Solenoid, left front
- SUM-0127: Solenoid, right front
- SUM-0137: Solenoid, left rear
- SUM-0147: 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.
