REF.: Listed in Table ENGINE: EPA04 Series 60 DATE: March 2014 SUBJECT: FLASH CODE 64 PID 103/FMI 1 ADDITIONS, REVISIONS, OR UPDATES Publication Number Platform Section Title Change DDC-SVC-MAN-0012 EPA04 Series 60 Flash Code 64 PID 103/FMI 1 This is a new diagnostic procedure to be added for low turbocharger speed (FMI1). NOTE: Page numbers are based on the most recent version of the individual publication and may be adjusted throughout the annual print cycle. TROUBLESHOOTING FLASH CODE 64 PID 103/FMI 1 This diagnosis is typically Turbocharger Speed Low. 1. Connect DDDL/DDRS 7.10 or newer. Go to step 2. 2. Turn the ignition ON (key ON, engine OFF). Go to step 3. 3. Check for any additional fault codes. Are there any other air management fault codes present? [a] Yes; diagnose the other air management fault code first. Verify repair. Refer to section verify repairs [b] No; go to step 4. 4. Turn the ignition OFF. Go to step 5. 5. Disconnect the Turbo Speed Sensor connector. Figure 1 Turbo Speed Sensor Figure 2 Turbo Speed Sensor Wiring 6. Measure the resistance between pin 1 of the turbo speed sensor and battery ground. Is the resistance less than 5 ohms? [a] Yes; replace the turbocharger speed sensor. [b] No; go to step 7. 7. Measure the resistance between pin 2 of the Turbo speed sensor connector and battery ground. Is the resistance less than 5 ohms? [a] Yes; replace the sensor. [b] No; go to step 8. 8. Remove the turbo inlet boot from the air filter and inspect the turbine inlet compressor wheel for defects. Is there damage present or does the turbine shaft stick or bind while being spun by hand? [a] Yes; replace the turbocharger. Verify repair. Refer to section verify repairs [b] No; go to step 9. 9. Inspect the air intake system and Exhaust Gas Recirculation (EGR) system for leaks or restrictions. Are there any leaks or restrictions present? [a] Yes; repair the leaks and/or restrictions as necessary. Verify repair. Refer to section verify repairs [b] No; replace the turbocharger speed sensor. Verify repair. Refer to section verify repairs VERIFY REPAIRS Check as follows: 1. Turn the ignition OFF. 2. Reconnect any electrical connections that were previously disconnected to perform the diagnostics. 3. Clear codes with DDDL/DDRS 7.10 or newer. 4. Start and bring the engine to operating temperature (over 60°C/140°F). 5. Verify the operation is satisfactory and no warning lamps illuminate. If warning lamps illuminate, troubleshoot the codes. ADDITIONAL SERVICE INFORMATION Additional service information is available in Power Service Literature.
