1 NUMBER: 07 DDEC VI 13 S.M. REF.: Table 1 ENGINE: MBE 900 DATE: August 2007 SUBJECT: SPN CHANGES AND ADDITIONS PUBLICATION: 6SE580 Three of the current SPN troubleshooting procedures have changed and a new SPN has been added as listed in Table 1. Section SPN/FMI Change Refer to section 105 Refer to section 106 SPN 3509/FMI 3 SPN 3509/FMI 4 SPN 3510/FMI 3 SPN 3510/FMI 4 Refer to section 108 SPN 3511/FMI 3 5 V Sensor Supply Bank 1 Failure replaces Multiplexer 1 Channel 1 or 2 Short or Open Circuit High 5 V Sensor Supply Bank 2 Failure replaces Multiplexer 2 Channel 1 or 2 Short or Open Circuit High 3 V Sensor Supply Bank 1 Failure replaces Multiplexer 3 Channel 1 or 2 Short or Open Circuit High Refer to section 109 SPN 3512/FMI 3 3 V Sensor Supply Bank 2 Failure is a new SPN Table 1 Manual Changes

2 105.1 SPN 3509/FMI 3 This diagnosis typically means the 5 V sensor supply bank 1 circuit failed high. This fault indicates that the MCM detects a short to power (voltage > 5.3) on any of the MCM pins listed in Table 2. Table 2 Charge Air Cooler Outlet Pressure Sensor 58 Charge Air Cooler Outlet Pressure Sensor 102 Inlet Air Delta P, Intake Throttle Valve 103 Inlet Air Delta P, Intake Throttle Valve 117 s for Short to Power Check SPN 3509/FMI 4 This diagnosis typically means the 5 V sensor supply bank 1 circuit failed low. This fault indicates that the MCM detects a short to ground (voltage < 4.7) on either of the MCM pins listed in Table 3. Table 3 Charge Air Cooler Outlet Pressure Sensor 58 Inlet Air Delta P, Intake Throttle Valve 117 s for Short to Ground Check.

3 106.1 SPN 3510/FMI 3 This diagnosis typically means the 5 V sensor supply bank 2 circuit failed high. This fault indicates that the MCM detects a short to power (voltage > 5.3) on any of the MCM pins listed in Table 4. TSS, Fuel Line Pressure Sensor, Fuel Compensation Pressure Sensor, Engine Oil Pressure Sensor Turbo Inlet Pressure/Temp Sensor, DPF Inlet and Outlet Pressure Sensors 85 Table 4 Fuel Line Pressure Sensor, Fuel Compensation Pressure Sensor 104 Engine Oil Pressure Sensor, Turbo Inlet Pressure/Temperature Sensor 105 s for Short to Power Check SPN 3510/FMI 4 This diagnosis typically means the 5 V sensor supply bank 2 circuit failed low. This fault indicates that the MCM detects a short to ground (voltage < 4.7) on either of the MCM pins listed in Table 5. TSS, Fuel Line Pressure Sensor, Fuel Compensation Pressure Sensor, Engine Oil Pressure Sensor 82 Turbo Inlet Pressure/Temp Sensor, DPF Inlet and Outlet Pressure Sensors 85 Table 5 s for Short to Ground Check 82

4 108.1 SPN 3511/FMI 3 This diagnosis typically means the 3 V sensor supply bank 1 circuit failed high. This fault indicates that the MCM detects a short to power (voltage > 3.2) on any of the MCM pins listed in Table 6. DOC Outlet Temperature Sensor 29 DOC Inlet Temperature Sensor, DOC Outlet Temperature Sensor, DPF Outlet Temperature Sensor Table 6 DOC Inlet Temperature Sensor 89 DPF Outlet Temperature Sensor 115 s for Short to Power Check 88

5 109.1 SPN 3512/FMI 3 This diagnosis typically means the 3 V sensor supply bank 1 circuit failed high. This fault indicates that the MCM detects a short to power (voltage > 3.2) on any of the MCM pins listed in Table 7. Fuel Temperature Sensor, Engine Coolant Temperature Sensor 55 Table 7 Fuel Temperature Sensor 77 Charge Air Cooler Outlet Pressure Sensor 102 Engine Oil Temperature/Pressure Sensor 108 Engine Coolant Temperature Sensor 110 s for Short to Power Check ADDITIONAL SERVICE INFORMATION Additional service information is available in the DDEC VI troubleshooting guides.
