| ITEM | DESCRIPTION |
|---|---|
| 1 | Vacuum control solenoid |
| 2 | Engine mounts |
| 3 | Connecting vacuum pipes |
The active engine mount system comprises:
- Two engine mounts,
- Vacuum control solenoid,
- Connecting vacuum pipes.
The ECM controls the engine mounts via the vacuum control solenoid. The mounts are on (solenoid activated which makes mounts soft) at idle speed, and are switched off when the engine speed goes above a predetermined threshold.
The threshold is temperature and engine speed dependant:
- Above 20° Celsius the mounts are switched off when the engine speed increases to 900 rpm.
- Below 20° Celsius the mounts are switched off when the engine speed increases to 1150 rpm.
