Continuity Test Procedure
NOTE:
The continuity test procedure for 14CUX (1990-Early 95 model) systems is similar to that for 14CU (1989 model). Note the addition of the tune select resistor test and the deletion of Test 28, which does not apply to 14CUX (1990-Early 95 model) systems.
- Release the Engine Control Module (ECM) connector retaining clip and remove the connector from the ECM. Access is gained by removing the front seat base trim of the right front seat.
- Remove the connector shroud and maneuver it along the harness until there is enough clearance to enable meter probes to be inserted into the back of the plug.
- There are six pin numbers (1, 13, 14, 27, 28 and 40) molded onto the rear of the plug. See Fig 1 . Pin wiring colors are identified in ENGINE CONTROL MODULE CONNECTOR TERMINAL IDENTIFICATION table.
