SPN 3510 EPA10 supply troubleshooting overview
The monitored parameter is the MCM 5V internal power supply. With the ignition on and engine off, the technician disconnects the Diesel Exhaust Fluid (DEF) pressure sensor connector and inspects the harness for bent, spread or corroded pins. Voltage from pin 3 on the harness side to ground is measured; a reading above 5.5 volts indicates a short to battery back to pin 84 of the ACM2 120-pin connector, while a lower reading points to a short at pin 2 back to pin 99. Each branch ends with verifying the repair.
