[a] If the resistance is greater than 3 Ω, replace the #2 injector. Verify repairs. [b] If the resistance is less than 3 Ω, gotostep9. 9. Disconnect injector # Measure the resistance between pin 9 on the valve cover side of the Front Injector Harness 12 pin [a] If the resistance is greater than 3 Ω, replace the #3 injector. Verify repairs. [b] If the resistance is less than 3 Ω, replace the under valve cover Injector Harness. Verify repairs. 11. Disconnect the 120 pin MCM connector. 12. Measure the resistance between pin 9 on the Front Injector Harness 12 pin connector and ground. If you are using J , measure between injector #3 pin 3 and ground. [a] If the resistance is less than 3 Ω, repair the short to ground between pin 11 of the MCM 120 pin connector and pin 9 of the Front Injector Harness 12 pin connector. Verify repairs. [b] If the resistance is greater than 3 Ω, call the Detroit Diesel Customer Support Center at for MCM replacement authorization.

4 SPN 4259/FMI 3 This diagnosis is typically injector #4, 5, or 6 spill control valve circuit has a short to battery/power. 1. Disconnect the Rear Injector Harness 12 pin connector. 2. Turn the ignition ON (key ON, engine OFF). 3. Measure the voltage between pin 1 on the MCM side of the Rear Injector Harness 12 pin [a] If there is voltage present, repair the short to power between pin 1 of the Rear Injector Harness 12 pin connector and pin 4 of the 120 pin MCM connector. Verify repairs. [b] If there is no voltage present, go to step Measure the voltage between pin 8 on the MCM side of the Rear Injector Harness 12 pin [a] If there is voltage present, repair the short to power between pin 8 of the Rear Injector Harness connector and pin 8 of the 120 pin MCM connector.
