4) Disconnect the ISC valve coupler and ECM coupler.
5) Check the continuity between terminals A and i, terminals
B and 0, terminals C and g, terminals D and \, terminals
E and 0, and terminals F and ^.
%
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.
$ ISC valve wire continuity: Continuity (*)
" 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
+ Tester knob indication: Continuity test (*)
Is the continuity OK?
YES Go to Step 2.
NO Lbl, W/Y, Dbr, R/W or Lg wire open.
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)
4) If OK, then measure the resistance between terminals 1 and
2, terminals 3 and 4.
$ ISC valve resistance: Approx. 30 ± 1.2 Ω at 20 °C (68 °F)
Is the resistance OK?
YES If wire is OK, intermittent trouble or faulty ECM.
NO Replace the ISC valve with a new one.
