3) Check Output Signal Circuit

Turn engine off and disconnect ECM harness connector. Disconnect EGR control solenoid valve harness connector. Verify harness continuity between ECM terminal No. 102 (Red/Black wire) and ground, and between EGR control solenoid valve harness connector terminal "a" (Red/Black wire) and ground. See Fig 1 and Fig 2 . If continuity does not exist, go to next step. If there is continuity, repair harness or connectors between ECM and EGR control solenoid valve as necessary.
