6) If OK, then check the continuity between each terminal and
ground.
! ISC valve continuity: ∞ Ω (Infinity)
$ 09900-25008: Multi-circuit tester set
& Tester knob indication: Resistance (Ω)
Are the resistance and continuity OK?
YES Go to Step 2.
Replace the ISC valve with a new one.
NO
(#8-84)
7) After repairing the trouble, clear the DTC using SDS tool.
(#8-39)
Step 2
1) Turn the ignition switch ON.
2) Measure the ISC valve voltage between O wire and ground.
! ISC valve voltage: Battery voltage
$ 09900-25008: Multi-circuit tester set
' Tester knob indication: Voltage (()
Is the voltage OK?
• O or Y/R wire open or shorted to ground, or
poor 2 connection.
• If wire and connection is OK, intermittent trou-
ble or faulty ECM.
YES
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
NO Open circuit in the O wire.

When using the multi-circuit tester, do not strongly
touch the terminal of the ECM coupler with a needle
pointed tester probe to prevent the terminal damage
or terminal bend.
3) After repairing the trouble, clear the DTC using SDS tool.
