INSPECTION
PROCEDURE
1. INSPECT VACUUM SWITCHING VALVE (for Active Control Engine Mount System)
(a) Measure the resistance.
| (1) Measure the resistance according to the value(s) in the table below. Standard Resistance:
If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |
|
(b) Check the operation of the vacuum switching valve (for active control engine mount system).
| (1) Using a vacuum pump, apply a vacuum of 67 kPa (503 mmHg, 19.8 in. Hg) to port (F) and check that the vacuum is maintained. OK: Vacuum pressure holds. If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |
|
| (2) Check that air flows from port (E) to port (G). Standard: Air flows from port (E) to port (G). If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |
|
| (3) Apply battery voltage to the terminals and check that air flows from port (E) to port (F). Standard: Air flows from port (E) to port (F). If the result is not as specified, replace the vacuum switching valve (for active control engine mount system). |
