ON-VEHICLE INSPECTION

1. REMOVE V-BANK COVER SUB-ASSEMBLY

2. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)

(a) Disconnect the vacuum switching valve connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 - 2	20°C (68°F)	37 to 44 Ω
1 - Body ground	Always	1 MΩ or higher
2 - Body ground	Always	1 MΩ or higher

If the result is not as specified, replace the vacuum switching valve assembly.

(c) When applying vacuum to port E, check that air is sucked into the filter.

If the result is not as specified, replace the vacuum switching valve assembly.

(d) Apply battery voltage to the connector, and check the VSV operation.

OK:

Measurement Condition

Specified Condition

Battery positive (+) → Terminal 1

Battery negative (-) → Terminal 2

Air is sucked into port E when a vacuum is applied to port F

If the result is not as specified, replace the vacuum switching valve assembly.
