Troubleshooting and Problem Solving

Common Issues After Installation

  • Check Engine Light
  • Rough Idle
  • Reduced Power
  • Coolant Leaks
  • Exhaust leaks at flange joints

Error Code Solutions

  • P0401: Insufficient EGR Flow - Install a compatible delete tuner to fully disable EGR monitoring and clear the code.
  • P2002: DPF Efficiency Below Threshold - Flash a proper full-delete calibration to turn off all DPF monitoring logic.
  • P242F: DPF Ash Accumulation - Confirm full delete tune is loaded and re-clear all stored fault codes.

How to Reset Check Engine Light After Installation

  1. Connect a compatible diesel delete tuner to the OBD-II port under the dashboard.
  2. Select the matched 6.7L Cummins full delete calibration and flash it to the PCM.
  3. Use the tuner’s DTC clear function to erase all stored emissions fault codes.
  4. Turn ignition off for 60 seconds, then restart the truck and complete a test drive.

What to Do If Your Vehicle Loses Power After Installation

  • Inspect all exhaust flanges, gaskets and hangers for exhaust leaks.
  • Confirm the correct 6.7L Cummins full delete tune is fully flashed to the PCM.
  • Check EGR block-off plates and intake connections for boost leaks.
  • Verify coolant reroute lines are not pinched or blocked after installation.

Long-Term Maintenance Tips

  • Regular Inspection: every 5,000–10,000 miles | Check exhaust joints, EGR hardware and coolant lines for leaks.
  • Routine Maintenance: Inspect coolant level and reroute hoses at every oil change.
  • Wear Parts Replacement: Exhaust gaskets, O-rings and clamps | Replace every 30,000 miles or after any disassembly.
  • Hardware Check: every 10,000 miles | Retorque exhaust bolts and inspect all hose clamps.
  • Storage Tips: Seal exhaust openings and store hardware in a cool, dry place if removed long-term.
  • Warranty Reminder: Following these maintenance guidelines will keep your 1 Year Limited Warranty valid
