2 SPN 641/FMI 7 This code typically means the Smart Remote Actuator 5 is in Failsafe Mode, Motor On. ACTUATOR CHECK Check as follows: 1. Using DDDL 7.0, perform the Turbo Hysteresis test. If the Turbo Hysteresis test is a pass, repeat the Turbo Hysteresis test to see if the results are the same. If the results are the same, refer to section. If the second Turbo Hysteresis testfails,thengotothenextstep. If the test results fail, go to the next step. 2. Turn the ignition OFF (key OFF, engine OFF). 3. Inspect the turbocharger electrical connectors. If bent, corroded or damaged pins are found, repair as necessary. Refer to section. If electrical connections are OK, go to the next step. NOTE: Failure to follow these instructions will result in an inaccurate diagnosis of the actuator or the 4. Perform Double Hysteresis test. Refer to section. 5. Did the Double Hysteresis test pass? Yes;gotonextstep. No; replace the turbo actuator. refer to section. 6. Remove the turbocharger and inspect for signs of foreign material contamination.

Disconnect the turbo actuator. 4. Check the actuator supply voltage. 5. Measure the voltage between pins 1 and 2 of the turbo actuator harness connector. If the voltage is less than 11 volts, repair the cause of the low voltage. Verify repairs. If the voltage is greater than 11 volts, go to the next step. 6. Turn the ignition OFF (key OFF, engine OFF). 7. Disconnect the MCM 120 pin connector. 8. Measure the resistance between pin 3 of the turbo actuator harness connector and pin 74 of the MCM 120 pin connector. If the resistance is greater than 3 Ω, repair the open circuit between pin 3 of the turbo actuator harness connector and pin 74 of the MCM 120 pin connector. Verify repairs. If the resistance is less than 3 Ω, go to the next step. 9. Measure the resistance between pin 4 of the turbo actuator harness connector and pin 75 of the MCM 120 pin connector. If the resistance is greater than 3 Ω, repair the open circuit between pin 4 of the turbo actuator harness connector and pin 75 of the MCM 120 pin connector. Verify repairs. If the resistance is less than 3 Ω, replace the turbo actuator. Verify repairs. NOTE: Failure to follow these instructions will result in inaccurate diagnosis of the actuator or the 10. Perform Double Hysteresis test. Refer to section.

If foreign material damage is found, repair the source of material entry. Replace the If no foreign material damage is found, replace the

5 SPN 641/FMI 14 This code typically means the Smart Remote Actuator 5, no Failsafe Mode, Motor Off. ACTUATOR CHECK Check as follows: 1. Using DDDL 7.0, perform the Turbo Hysteresis test. [c] IftheTurboHysteresistestfails,gotostep7. If you are unable to perform the Turbo Hysteresis test, go to the next step. If the Turbo Hysteresis test is a pass, repeat the test to see if the results are the same. If the results are the same, verify repairs. If the repeat test fails, go to the next step. 2. Turn the ignition OFF (key OFF, engine OFF). 3. Disconnect the turbo actuator. 4. Turn key ON (key ON, engine OFF). 5. Check the actuator supply voltage. 6. Measure the voltage between pins 1 and 2 of the turbo actuator harness connector. If the voltage is less than 11 volts, repair the cause of the low voltage. Verify repairs. If the voltage is greater than 11 volts, go to the next step. 7. Turn the ignition OFF (key OFF, engine OFF). 8. Disconnect the MCM 120 pin connector. 9. Measure the resistance between pin 3 of the turbo actuator harness connector and pin 74 of the MCM 120 pin connector. If the resistance is greater than 3 Ω, repair the open circuit between pin 3 of the turbo actuator harness connector and pin 74 of the MCM 120 pin connector. Verify repairs.
