Electronic fault codes active or high counts of inactive fault codes
View and troubleshoot the fault codes with INSITEm electronic service tool. Refer to the Troubleshooting and Repair Manual, CM2150 Electronic Control System, ISB, ISC, ISL, ISLe,
ISDe, and QSB3.3 Engines, Bulletin 4021570.
Soot load of the Aftertreatment Diesel Particulate Filter is too low
A stationary regeneration can be performed with the vehicle mounted switch only when the DPF
lamp is illuminated. INSITETM electronic service tool can perform a stationary regeneration if the DPF lamp is illuminated or not illuminated. Refer to Procedure 014-013 (Aftertreatment Testing) in
Section 14.
The correct Stationary Regeneration procedure is not being followed
Refer to the OEM instructions on how to perform a stationary regeneration or refer to Procedure
014-013 (Aftertreatment Testing) in Section 14
Clutch pedal is depressed
The clutch pedal must be released for stationary regeneration to activate. Monitor the clutch pedal
position switch with INSITETII electronic service tool and verify it is released. If the vehicle does not have a clutch pedal, verify the clutch pedal position switch is not installed in features and parameters. If necessary, check the clutch switch adjustment, switch, and circuit. Refer to Procedure 019-009 (Clutch Pedal Position Switch) in Section 19 in the ISB, ISC, ISL, ISDe, and QSB3.3 CM2150 Electronic Control System Troubleshooting and Repair Manual, Bulletin 4021570. Refer to Procedure 019-010 (Clutch Pedal Position Switch Circuit) in Section 19 in the ISB, ISC, ISL, ISDe, and QSB3.3 CM2150 Electronic Control System Troubleshooting and Repair Manual, Bulletin 4021570.
Brake pedal is depressed
The brake pedal must be released for stationary regeneration to activate. Monitor the brake pedal
position switch with INSITE”” electronic service tool and verify it is released. If necessary, check the vehicle brake switch and circuit. Refer to Procedure 019-088 (Brake Pedal Position Sensor)
in Section 19 in the ISB, ISC, ISL, ISDe, and QSB3.3 CM2150 Electronic Control System
Troubleshooting and Repair Manual, Bulletin 4021570. Refer to Procedure 019-089 (Brake Pedal
Position Sensor Circuit) in Section 19 in the ISB, lSC, lSL, ISDe, and QSB3.3 CM2150 Electronic
Control System Troubleshooting and Repair Manual, Bulletin 4021570.
PTO or Remote PTO is engaged
Stationary regeneration will not activate if the engine is operating in PTO or Remote PTO. Verify
the PTO or remote PTO switch is in the OFF position. If necessary, check the cruise control/
PTO selector switch and circuit. Refer to Procedure 019-021 (Cruise Control or PTO ON/ OFF Switch) in Section 19 in the ISB, lSC, ISL, ISDe, and QSB3.3 CM2150 Electronic Control System Troubleshooting and Repair Manual, Bulletin 4021570. Refer to Procedure 019-022 (Cruise Control or PTO ON/OFF Switch Circuit) in Section 19 in the ISB, ISC, ISL, ISDe, and QSB3.3 CM2150 Electronic Control System Troubleshooting and Repair Manual, Bulletin 4021570.
Vehicle speed is greater than zero
Stationary regeneration will not activate if the vehicle speed is greater than zero. Use INSITE””
electronic service tool to monitor the vehicle speed while the vehicle is not moving. If the monitor
shows speed, check the sensor and circuit. Refer to Procedure 019-090 (Vehicle Speed Sensor,
Digital Input), 019-091 (Vehicle Speed Sensor, Magnetic Pick Up) in Section 19 in the ISB, ISC,
ISL, ISDe, and QSB3.3 CM2150 Electronic Control System Troubleshooting and Repair Manual,
Bulletin 4021570. Refer to Procedure 019-093 (Vehicle Speed Sensor Circuit) in Section 19 in the
ISB, ISC, ISL, ISDe, and QSB3.3 CM2150 Electronic Control System Troubleshooting and Repair Manual, Bulletin 4021570
Accelerator pedal position is greater than zero
Stationary regeneration will not activate if the accelerator pedal position is greater than zero.
Check for accelerator pedal or lever restriction.
Use INSITETM electronic service tool to monitor the percent throttle reading. Check the accelerator
pedal position sensor and the circuit. Refer to Procedure 019-085 (Accelerator Pedal or Level Position Sensor) in Section 19 in the ISB, ISC, ISL, ISDe, and QSB3.3 CM2150 Electronic Control
System Troubleshooting and Repair Manual, Bulletin 4021570.
Transmission is not in Park, if provided, otherwise in Neutral
Verify the transmission is in Park, if provided, otherwise in Neutral. Refer to the OEM instructions.
Electronic control module (ECM) calibration is malfunctioning
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history for applicable fixes to the calibration stored in the ECM. Refer to the calibration history spreadsheet ecm_calibration_rev_history .xlson QuickServe® Online Internet Website or the INCALTM calibration CD. Compare the calibration stored in the ECM with the engine rating and the Control Parts List (CPL), Bulletin 4021326 or 4021327. If necessary, recalibrate the ECM. Refer to the appropriate electronic service tool manual and Procedure 019-032 (ECM Calibration Code) in Section 19, in the Troubleshooting and Repair Manual, CM2150 Electronic Control System, ISB, ISC, ISL, ISLe, ISDe, and QSB3.3 Engines, Bulletin 4021570.
