Is the continuity OK?
Step 2
1) Turn the ignition switch OFF.
2) Disconnect the ISC valve coupler.
3) Check the continuity between terminals

4) If OK, then measure the resistance between terminals
1
and
2
, terminals
3
and
4
.

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.
