Heavy Duty Scanner, Clearing Codes or Forced Regeneration
 

For heavy duty scanners, the following important factors and recommendations should be considered when clearing codes or performing a forced regeneration on heavy equipment and trucks:



Features Required for a High Performance Scanner

1. Reading and Clearing Codes:
– The scanner must support reading and clearing Active and Inactive DTCs (Diagnostic Trouble Codes) for various systems; engine, transmission, ABS, exhaust aftertreatment, etc.

2. Forced Regeneration:
– For vehicles with exhaust aftertreatment systems, it must support regeneration of the DPF (Diesel Particulate Filter).
– Some models also offer advanced regeneration features such as Monitoring smoke levels and Temperature control during the process.

3. Broad Compatibility:
– Ensures compatibility with major heavy vehicle manufacturers such as Cummins, Caterpillar, Detroit Diesel, Volvo, Mack, Paccar, etc.

4. Data Stream Monitoring:
– Real-time data monitoring to assess vehicle performance and diagnose issues during regeneration or other processes.

5. User-Friendly Interface:
– Easy-to-operate menus and clear instructions for beginners and professionals.

6. Upgradability:
– Regular updates to support new vehicle models and ECM software changes.

Forced Regeneration by Scanner

1. Safety Precautions:
- Make sure the vehicle is parked in a safe open area to avoid heat hazards.
- Exhaust temperatures will be high during DPF regeneration so have a fire extinguisher ready.

2. Forced Regeneration Procedure:
- Connect the scanner to the vehicle's diagnostic port (usually 6 or 9 pin).
- Turn ignition key "ON" (engine off).
- Select DPF Regeneration from the scanner menu.
- Follow the on-screen instructions, including maintaining idle speed and other conditions.
- Monitor the operation to ensure it is completed successfully.

3. Clearing Codes:
- Once the regeneration is complete or repair work is complete, use the scanner to clear the stored codes.
