4) Remove the front panel. (#AN650K3 9-8)
5) Disconnect the ISC valve coupler and ECM couplers.
6) Check the continuity between terminals A (B/Lg) and m, ter-
minals B (P/W) and t, terminals C (G) and s, terminals D
(W/B) and r.
$ ISC valve lead 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 Y, B/Lg, P/W, G or W/B wire open.
7) After repairing the trouble, clear the DTC using SDS tool.
(Refer to the SDS operation manual for further details.)
Step 2
1) Remove the front box. (#AN650K3 9-18)
2) Measure the resistance between terminals A and B, termi-
nals C and D.
$ ISC valve resistance: Approx. 80 Ω at 25 °C (77 °F)
Is the resistance OK?
YES If wire is OK, intermittent trouble or faulty ECM.
NO Replace the ISC valve with a new one.
3) After repairing the trouble, clear the DTC using SDS tool.
(Refer to the SDS operation manual for further details.)
