WARNING: This page is about a different variant/trim than selected.
The Multi-Displacement System (MDS) has the following detectable issues:
- Solenoid circuit
- Fail to deactivate a cylinder(s)
- Fail to reactivate a cylinder(s)
- Low oil pressure
| CONDITION | POSSIBLE CAUSES | CORRECTION |
|---|---|---|
| MDS does not activate | 1. Low oil pressure. | 1. Check for proper oil pressure. |
| 2. Bad oil temperature sensor. | 2. Replace the oil temperature sensor. | |
| 3. Malfunctioning MDS solenoid. | 3. Replace the solenoid. | |
| 4. Malfunctioning MDS tappet. | 4. Replace tappet(s). | |
