Voltage Signal: Testing and Inspection

ECU System:





To test the Battery Signal to the ECU locate pin #3 of connector C50-3 on the ECU, and test for the presence of power. Battery voltage should be read at this pin at all times.

NOTE: To test pins do not remove the connector from the ECU, instead insert a straight pin or needle from the backside of the connector to access the pin.
