3. Measure the resistance between the oscillator and the certification ECU to check for an open circuit in the wire harness.

   Resistance: 

   Below 1 Ω. 

4. Measure the resistance between the oscillator and the certification ECU to check for an short circuit in the wire harness.

   Resistance: 

   10 kΩ or higher 

   HINT:

   Refer to the WIRING DIAGRAM  for connection of each terminal.
