5V  

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

This 5V must only be used for a switch or 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

 

In general, switching voltage is 0V to 5V analogic (sensor), up to B+ (switch)

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)
