Diagnostic trouble code (DTC) information

Condition




The Suspension Module (SUM) receives information from the solenoids on each suspension unit. Diagnostic trouble code (DTC) SUM-0116, 0126, 0136 or SUM-0146 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-0116: Solenoid, left front
- SUM-0126: Solenoid, right front
- SUM-0136: Solenoid, left rear
- SUM-0146: 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.
