I NSPECTION OF ISC VALVE
1.
INSPECT ISC VALVE RESISTANCE
Using an ohmmeter, measure the resistance between ter-
minal B1 — S1 or S3, and B2 — S2 or S4.
Resistance: B1 - 51 or S3 10 - 30
B2 - S2 or S4 10 - 30
If resistance is not as specified, replace the ISC valve.
2.
INSPECT ISC VALVE OPERATION
(a)
Apply battery voltage to terminals B1 and B2, and
while repeatedly grounding S1 — S2 — S3 — S4 — S1
in sequence, check that the valve moves toward the
closed position.
(b)
Apply battery voltage to terminals B1 and B2, and
while repeatedly grounding S4 — S3 — S2 — S1 — S4
in sequence, check that the valve moves toward the
opened position.
If operation is not as specified, replace the ISC valve.
