FAP regeneration problem Tesmec TrenchTronic 950R - Slicer

Are you experiencing a Tesmec FAP regeneration problem with your TrenchTronic 950R slicer?

This can lead to costly downtime and lost productivity. Fortunately, there are effective solutions to remedy these problems.

Removal of the ARD head, which injects fuel into the filter to burn off accumulated particles, is an option. By eliminating this head and any other anti-pollution devices present, you reduce the risk of malfunction and simplify maintenance.

The Adem 4 ECU has also been modified to incorporate the new operating parameters of the CAT C7.1 ACERT engine. This reprogramming ensures optimum adaptation to new configurations without emission control devices.

So, by adjusting the ECU and eliminating certain components, you improve reliability and make significant savings over the long term.

Fault diagnosis

Accurate diagnostics are essential for identifying and effectively resolving emission control system problems. This avoids costly repairs and minimizes downtime.

Common Adem 4 ECU faults

• DPF saturation at 117%: This fault indicates that the diesel particulate filter (DPF) is clogged beyond its maximum capacity. This can lead to increased backpressure, reducing engine efficiency.
• Degraded mode without power: When this mode is activated, the vehicle loses considerable power. This often occurs to protect the engine when the ECU detects a serious problem, such as excessive DPF saturation or AdBlue system malfunction.

Eliminating faulty emission control devices improves overall vehicle reliability. It also reduces the costs associated with frequent repairs and costly parts replacements.

FAP regeneration problem on Tesmec: complete solution on CAT C7.1 ACERT engine and ARD system

If you're faced with a DPF regeneration problem on a Tesmec 950R, you should know that this machine is generally equipped with a CAT C7.1 ACERT engine compliant with Tier 4 Final / Stage V standards, combined with an ADEM 4 ECU and an aftertreatment system including a DPF and an ARD (Aftertreatment Regeneration Device).

These components, which are supposed to reduce pollutant emissions, quickly become a source of errors, incomplete regeneration and even total machine downtime.

1. Complete emission control system diagnostics

We start with an in-depth diagnosis focusing on the engine and the Adem 4 ECU. By analyzing faults relating to the DPF, ARD, soot levels and regeneration cycles, we can pinpoint the cause of the malfunction.

2. Adem 4 ECU reading and mapping extraction

A full microcontroller flash readout of the ECU is performed. The file .bin contains all engine parameters, including those related to FAP and ARD management.

3. Reprogramming: error removal and emulation

We then modify the file to :

• Eliminate regeneration errors

• Emulating DPF and soot rate operation

• Neutralize the ARD system if necessary, to prevent accidental tripping

• Disable AdBlue injection if present and subject to failure

Checksums are recalculated to guarantee stable operation, with no degraded modes.

4. Result: Optimum operation without blocked regeneration

After reinjection of the corrected file, your Tesmec 950R returns to its original performance, without the constraints of the automatic regeneration system. No more power loss, no more warning lights, no more hassle.

Optimize the Reliability of your Tesmec 950R with a targeted Engine Reprogramming

Eliminate emission-related faults and restore your machine to its full potential.

✅ Elimination of FAP regeneration errors
✅ Elimination of degraded mode and torque limitation
✅ Recovery of original engine performance
✅ Disappearance of dashboard alerts
✅ No parts to replace, zero unnecessary costs

Engine reprogramming is a reliable and long-lasting solution for solving FAP regeneration problems on Tesmec, particularly on models equipped with the CAT C7.1 ACERT engine and Adem 4 ECU.

By intervening directly on engine mapping, we remove the restrictions associated with the ARD (Aftertreatment Regeneration Device) system and neutralize problematic regeneration functions. This enables :

• Avoid interruptions due to soot or blocked FAP errors

• Maintain constant power, even in difficult conditions

• Eliminate unnecessary and stressful dashboard alerts

Thanks to this optimization, your machine runs without interruption, without degradation, and without costly replacement of post-processing components (such as DPF or temperature sensors).
