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

INSPECTION
1. REMOVE VSV
2. INSPECT VSV
(a) Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 33 ± 39 W at 20°C (68°F)
If there is no continuity, replace the VSV.
(b) Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.
If there is continuity, replace the VSV.
(c) Inspect the VSV operation.
(1) Check that air flows from ports E to G.
(2) Apply battery positive voltage across the terminals.
(3) Check that air flows from port E to filter.
If operation is not as specified, replace the VSV.

1. REMOVE VSV
2. INSPECT VSV
(a) Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 30 ± 34 W at 20°C (68°F)
If there is no continuity, replace the VSV.
(b) Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.
If there is continuity, replace the VSV.
(c) Inspect the VSV operation.
(1) Check that air dose not flow from ports E to F.
NOTICE:
Never apply more than 93 kPa (0.95 kgf/cm
2, 13.5 psi) of
pressure compressed air to the VSV.
(2) Apply battery positive voltage across the terminals.
(3) Check that air flows from ports E to F.
If operation is not as specified, replace the VSV.
