| 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). | |
