4) Disconnect the ISC valve coupler and ECM coupler.
5) Check the continuity between terminals

Is the continuity OK?
Step 2
1) Turn the ignition switch OFF.
2) Disconnect the ISC valve coupler.
3) Check the continuity between terminals
1 and
3, terminals
2 and
4.
$ ISC valve continuity: Approx. ∞ Ω (Infinity)
(Terminal
1 – Terminal
3)
(Terminal
2 – Terminal
4)
4) If OK, then measure the resistance between terminals
1 and
2, terminals
3 and
4.
$ ISC valve resistance: Approx. 30 ± 1.2

Is the resistance OK?
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.
YES Go to Step 2.
NO Lbl, W/Y, Dbr, R/W or Lg wire open.
ECM coupler (Harness side)
1
YES If wire is OK, intermittent trouble or faulty ECM.
NO Replace the ISC valve with a new one.
