Vacuum Switching Valve (For Acis) -- On-Vehicle Inspection



1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)

  1. Disconnect the vacuum switching valve connector.

  1. 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
    If the result is not as specified, replace the vacuum switching valve assembly.


  1. Check the vacuum switching valve operation.
