DPF REGEN & DERATE BYPASS: Bi-Directional Diagnostic Tool for Truck Aftertreatment Limp Mode (SCR/DEF/DPF)

EXIT AFTERTREATMENT LIMP MODE. NO DEALER REQUIRED.

When your truck/engine enters Limp Mode due to DPF, DEF, or SCR faults, you're facing a forced shutdown or severe derate. A basic code reader cannot fix this—you need active, bi-directional control.

This Advanced Diagnostic Scanner is specifically engineered to perform the active commands required to clear high soot levels, instantly exit Limp Mode, and keep your truck moving, saving you hundreds in service fees and avoiding costly downtime.

Perfect Compatibility with your Truck / Engine. Simply choose your model from the drop down boxes above when ordering.

🔥 CORE FUNCTION: Active DPF Regeneration

This feature pays for itself with the first use:

• Forced DPF Regeneration: The primary function that saves you the most time and money. Manually start the regen cycle on the spot to burn off excessive particulate matter and immediately exit the system-mandated Limp Mode.

• Bi-Directional Control: Perform active tests and resets that basic tools cannot, giving you complete control over critical engine and aftertreatment components.

✅ COMPREHENSIVE DIAGNOSTICS & SYSTEM CONTROL

Beyond DPF Regen, this tool provides full professional shop capability:

• Full ECU Coverage: Access and communicate with all critical control units, including Engine, Transmission, Braking System (ABS), Fuel System, Instrument Panel, and Drivetrain.

• Code Management: Read, store, and erase both Active (DM1) and Logged (DM2) Diagnostic Trouble Codes (DTCs) across all ECUs.

• Special Functions: Perform ABS Testing, EVAP Tests, and O2 Sensor Tests.

Some of the Critical Faults It Detects (Including Derate Triggers):

Engine Faults

• Engine oil pressure too low or too high

• Coolant temperature outside normal range (too high or too low)

• Intake manifold temperature excessively elevated

• Torque limiting (engine-derate) engaged

• Fuel rail pressure below required threshold

• Turbo boost pressure exceeding safe limits

Emissions & After-Treatment 

• DPF soot accumulation beyond allowable level

• After-treatment system fault detected

• DEF pressure too low (on models equipped with DEF)

Electrical, Sensor & Communication Failures

• Battery voltage outside acceptable range

• Crankshaft speed sensor fault

• CAN communication error

• Accelerator pedal signal out of range or abnormal

📊 Real-Time Monitoring & Code Detail

• Live Data Graphing: Read, store, and playback live PCM data stream with graphic display, allowing you to monitor system health and confirm repairs visually.

• Accurate Troubleshooting: Display DTC definitions, monitor and I/M readiness status (emissions), and vehicle information (VIN, CIN, and CVN).

Monitor key engine, fuel, electrical and system metrics in real time, some examples:

• Engine Speed (RPM)

• Coolant Temperature

• Oil Pressure

• Fuel Rate

• Turbo/Intake Manifold Pressure & Temperature

• Throttle Position

• Battery Voltage

• Engine Hours

• Transmission Gear Position (on supported models)

• Fuel Level (on models that provide this data)

• ... and more
