2 SPN 5741/FMI 4 - GHG14 2 SPN 5741/FMI 4 - GHG14 Soot Sensor Inter-Digital Electrode Short Circuit Table 1. SPN 5741 / FMI 4 Soot Sensor Heater High Current Flow Soot Sensor Temperature Verify repairs by using DiagnosticLink Soot Sensor Panel inspection routine. NOTE: When the engine starts, soot sensor will cycle through three modes: protective heating of exhaust temperature dew point 200 C (392 F) to allow moisture to evaporate, heater active regeneration 800 C (1472 F) to clean soot, and measurement mode for duration of key cycle. 1. Turn the ignition key ON (key ON, engine OFF). 2. Using DiagnosticLink, check for any communication or voltage fault codes. Are any other fault codes present? a. Yes; repair those fault codes first. b. No; Go to step 3. 3. Disconnect soot sensor harness connector. 4. Inspect the soot sensor and harness connector for signs of damaged, bent, spread, corroded or unseated (pushed out) pins and signs of moisture in the connector or wire damage near the connector. Is any damage found? b. No; replace soot sensor. Refer to section "Removal of the 2V2/2HH Soot Sensor". Verify repairs. 4 All information subject to change without notice.

6 12-14 1. Turn the ignition OFF. 2. Disconnect the soot sensor harness connector. 3. Inspect the harness and connector for signs of damage, bent, spread, corroded or unseated (pushed out) pins. Is any damage found? b. No; Go to step 4. 4. Inspect soot sensor wiring between the sensor probe and the sensor control unit. Is any damage found? a. Yes; replace the soot sensor. Refer to section "Removal of the 2V2/2HH Soot Sensor". Verify repairs. b. No; Go to step 5. 5. Inspect the harness and connectors between soot sensor and the ACM for signs of damage, chaffing, overheating, or corrosion. Is any damage found? b. No; Go to step 6. All information subject to change without notice. 7 v2152981 Copyright 2014 DETROIT DIESEL CORPORATION
4 SPN 5741/FMI 13 - GHG14 6. Disconnect the ACM 120-pin connector. 7. Inspect the ACM 120-pin harness connector for signs of damage, bent, spread, corroded or unseated (pushed out) pins and signs of moisture in the connector or wire damage near the connector. Is any damage found? b. No; Go to step 8. 8. Measure the resistance between pin 3 of the soot sensor connector, harness side and pin 44 of the ACM 120-pin connector, harness side. Is the resistance less than 5 ohms? a. Yes; Go to step 9. b. No; repair the wire between pin 3 on the harness side of the soot sensor connector and pin 44 of the ACM 120- pin connector. Verify repairs. 9. Measure the resistance between pin 4 of the soot sensor connector, harness side and pin 61 of the ACM 120-pin connector, harness side. Is the resistance less than 5 ohms? a. Yes; Go to step 10. b. No; repair the wire between pin 4 on the harness side of the soot sensor connector and pin 61 of the ACM 120- pin connector. 10. Measure the resistance between pin 3 of the soot sensor connector, harness side and battery ground. Is the resistance greater than 10K ohms? a. Yes; Go to step 11. b. No; repair the shorted wire between pin 3 on the harness side of the soot sensor connector and ground. Verify repairs. 11. Measure the resistance between pin 4 of the soot sensor connector, harness side and battery ground. Is the resistance greater than 10K ohms? a. Yes; Go to step 12. b. No; repair the shorted wire between pin 4 on the harness side of the soot sensor connector and ground. Verify repairs. 12. Measure the resistance between pins 44 and 61 on the ACM 120-pin connector, component side. Is the resistance between 50 to 70 ohms? a. Yes; replace soot sensor. Refer to section "Removal of the 2V2/2HH Soot Sensor". Verify repairs. b. No; replace the ACM. Refer to section "Removal of the Aftertreatment Control Module". Verify repairs. 8 All information subject to change without notice. Copyright 2014 DETROIT DIESEL CORPORATION v2152981
