2 2 SPN 3250/FMI 0 - EPA10 2 SPN 3250/FMI 0 - EPA10 This diagnostic is typically Diesel Oxidation Catalyst (DOC) Outlet Temperature Very High. 1. Shut off the engine, apply the parking brake, chock the wheels, and perform any other applicable safety steps. 2. Connect DDDL/DDRS 7.x (for best results, ensure DDDL/DDRS is up-to-date). 3. Turn the ignition ON (key ON, engine OFF). 4. Check for multiple fault codes. a. If codes other than SPN 3250/FMI 0 are active, troubleshoot those first. b. If only SPN 3250/FMI 0 and related codes are present, Go to step Monitor the DOC outlet temperature. a. If the temperature is greater than 760 C (1400 F), Go to step 10. b. If the temperature is less than 760 C (1400 F), Go to step 6. WARNING: PERSONAL INJURY To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked. WARNING: ENGINE EXHAUST To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic. 6. With DDDL 7.X connected, run the engine at 1200 RPM for 10 minutes. 7. Monitor the Diesel Oxidation Catalyst (DOC) inlet temperature and the DOC outlet temperature. Are the temperatures within 25 C (77 F) of each other? a. If yes; Go to step 10. b. If no; Go to step Turn the ignition OFF. 9. Disconnect the DOC outlet temperature sensor and inspect the connector for damaged, bent, spread, or corroded pins. If the temperature sensor connector is OK, check the connections upstream of the Aftertreatment Control Module (ACM2.1): the Aftertreatment Device (ATD) harness 14 pin connector pin 3, the VIH 47-pin connector pin 7, and the ACM pin connector pin 27. a. If harness damage is found, repair as necessary. b. If no harness damage is found, replace the DOC outlet temperature sensor. Refer to section "Removal of the EPA10 Diesel Oxidation Catalyst Outlet Temperature Sensor". 10. Perform an Idle Speed Balance Test using DDDL 7.X. Retain the log file. Refer to section "Checking the Idle Speed Balance". 11. Was a faulty fuel injector/cylinder identified? a. If yes, repair the faulty fuel injector/cylinder, and repeat the Idle Speed Balance Test to verify the repair. Go to step 22. b. If no; Go to step Remove the ATD. Refer to section "Removal of the 1-BOX from the Vehicle". Refer to section "Removal of the EPA10 2-Box (2V2) from the Vehicle". 13. Disassemble the ATD and inspect the inlet face of the DPF substrate for contamination. a. If coolant contamination is found (white residue on inlet face of the DPF and a sweet smell from exhaust), Go to step All information subject to change without notice.

3 b. If oil contamination is found (oil residue or paste on DPF Inlet face or an oil lacquer on the inlet flange), Go to step 17. c. If fuel contamination is found (inlet flange washed clean), Go to step 19. d. If no contamination is found, obtain pictures of the inlet flange, the DOC outlet face, and the DPF inlet and outlet faces. Contact the Detroit Customer Support Center at with these pictures and the log files from the Idle Speed Balance Test. Question the operator about coolant usage. Visually inspect the coolant reservoir for low level. Repair the cause of coolant entry as necessary and Go to step 21. Question the operator about excessive oil consumption. Repair the cause of oil contamination and Go to step 21. Inspect the ATD components for fuel contamination. Repair the cause of fuel contamination and Go to step 21. Install the ATD. Refer to section "Installation of the 1-BOX to the Vehicle". Refer to section "Installation of the EPA10 2-Box (2V2) to the Vehicle". WARNING: HOT EXHAUST During parked regeneration the exhaust gases will be extremely HOT and could cause a fire if directed at combustible materials. The vehicle must be parked outside. NOTE: The parked regeneration is successful if the DOC outlet temperature is within 100 C (212 F) of the DOC Model Delay. 22. Perform a parked regeneration, reset ash accumulators, and a log file of the successful regeneration to Detroit Customer Support Center. Verify repairs. Refer to section "Performing a Parked Regeneration Using DDDL". Refer to section "Resetting the EPA07/10/GHG14 Diesel Particulate Filter Ash Accumulators". a. If the regeneration is successful, release vehicle. b. If regeneration is not successful, repeat procedure beginning at Step 12. If second attempt is not successful, contact Detroit Customer Support Center at for additional support. All information subject to change without notice. Copyright 2012 DETROIT DIESEL CORPORATION 5

Turn the ignition ON (key ON, engine OFF). 4. Check for multiple fault codes. a. If codes other than SPN 3250/FMI 15 are active, troubleshoot those first. b. If only SPN 3250/FMI 15 and related codes are present, Go to step Monitor the DOC outlet temperature. a. If the temperature is greater than 760 C (1400 F), Go to step 11. b.
