2. Disconnect SMEC 14-way electrical connector, then connect an ohmmeter between terminal No. 10 of connector and tan wire terminals of No. 3 and No. 4 injector electrical connectors.
3. If ohmmeter does indicate continuity, replace SMEC.
CAUTION: Before replacing the SMEC, check the Y12 terminal in cavity No. 10 of the 14-way connector to make sure it is not spread apart causing a poor connection.
