 5V  

Never connect the black wire to the vehicle's ground !

This 5V is used for sensor power

Next steps :

  • check for oxidation marks in the connectors
  • check the continuity of the wires with ohmmeter (R<5Ω for correct operation)

Input signal

  

Input signal compatible with ECU setup is 0 to 5V analogic

For General Purpose Input use, the switching voltage depend of the configuration, and need to be checked in ECU setup

Next steps :

  • check for oxidation marks in the connectors
  • check the switch or sensor connected
  • check the continuity of the wires with ohmmeter (R<5Ω for correct operation)
