- Check for 24V at pins 1 and 2 of the 40 pin customer connector.
- Check for ground at pins 34 and 35 of the 40 pin customer connector.
- Run a jumper wire from pin 23 to pin 34.
- Run a jumper wire from pin 24 to pin 35.
- Set the "Engine State Control Input Configuration" to "Hardwired Input" in Cat Electronic Technician (ET).
