Common Faults:-

Total Loss of Accelerator Pedal Response: The truck idles normally, but stepping on the accelerator pedal does nothing. This frequently persists even after changing the physical pedal or checking the wiring harness.

No-Start Conditions: The truck may crank but will not start, often accompanied by an "Immobilizer Active" message on the dashboard.

Transmission Unresponsiveness: The transmission fails to shift or coordinate, and the "N" (Neutral) indicator disappears entirely from the instrument cluster.

Intermittent Heat-Related Failures: The truck may start and drive perfectly when cold, but once the engine bay or cab heats up, the unit cuts out or drops into emergency limp mode.

CAN-Bus / Communication Blackouts: Total communication loss occurs between the CPC-3 and other major control modules like the MCM (Engine), TCM (Transmission), ACM (Aftertreatment), or ESP/EBS (Brakes). Diagnostic scanners will often throw a "Module Not Detected" error.

- Missing Dashboard Telemetry: The AdBlue fluid level reading drops completely off the instrument display.

Fault Reporting

Diagnose your fault quickly

Accurate Diagnostics = Better, Faster ECU Remanufacturing

Providing clear and detailed fault information is one of the most important steps in the remanufacturing process. The more accurate the diagnostics, the faster we can identify the root cause, reduce turnaround times, and ensure a reliable repair.

To help us deliver the best possible results, please include the following information when sending your unit:

Fault Description

Give a clear, simple explanation of the issue as observed by you or your technician.

What is the vehicle or system doing?
What is it not doing that it should?

A concise description helps us quickly understand the symptoms and focus on the right areas.

When the Fault Occurs

Understanding when the issue happens is key to identifying patterns.

Please let us know if the fault appears:

During start-up
Only at operating temperature
In specific gears or modes
Under load or acceleration
Intermittently or consistently

This information allows us to replicate real-world conditions and pinpoint the cause more efficiently.

Diagnostic Trouble Codes (DTCs)

Include all fault codes retrieved using a diagnostic tool
These provide a vital starting point in identifying affected systems or components

DTCs combined with live data give us a much clearer picture than codes alone.

Live (Real-Time) Data

Where possible, include relevant readings from your diagnostic equipment, such as:

Battery and charging voltages
Sensor values (temperature, pressure, position, speed, etc.)
Actuator positions
Any readings that appear abnormal or out of range

Live data helps us verify faults, confirm component behaviour, and accurately reproduce the issue during testing.

Why This Matters

Accurate and detailed diagnostics allow us to:

Identify faults faster
Reduce unnecessary testing
Improve repair accuracy
Minimise turnaround time
Ensure long-term reliability of the ECU

If you’re unsure about any of the above, feel free to get in touch — our team is always happy to help.
