Testing Procedure

CAUTION: Tests requiring connector to be removed from ECM, must have meter probes inserted into back of connector. If probes are inserted into connector sockets, damage will occur to sockets resulting in poor connections when connector is reconnected.

To carry out tests when 40 way connector is connected to the Engine Control Module (ECM), it is necessary to remove the two screws securing the shroud to the connector to enable the multi-meter probes to be inserted into the back of the appropriate pin.

  1. Release harness connector from ECM. Access is gained by removing front seat base trim of front right hand seat. Remove connector shroud and maneuver it along harness to enable meter probes to be inserted into back of connector.
  2. Only pin numbers 1, 13, 14, 27, 28 and 40 are molded onto rear of connector. See Figure .
