INSPECTION
1. REMOVE RELAY BOX COVER
2. REMOVE EFI MAIN RELAY (Marking: EFI)
3. INSPECT EFI MAIN RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals 1 and 2.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and
5.
If there is continuity, replace the relay.
4. INSPECT EFI MAIN RELAY OPERATION
(a) Apply battery positive voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is continuity be-
tween terminals 3 and 5.
If there is no continuity, replace the relay.
5. REINSTALL EFI MAIN RELAY
6. REINSTALL RELAY BOX COVER

If there is no continuity, replace the VSV.
4. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is continuity, replace the VSV.
5. INSPECT VSV OPERATION
(a) Check that air flows from port E to port G.
(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
6. REINSTALL VSV
(a) Install the VSV with the screw.
(b) Connect the 3 vacuum hoses to the VSV.
