To help us process your repair accurately and avoid surprises:
- ⚠️ If your CPC4 arrives with no communication, expect warning lights on the dash once it goes back in. A dead module cannot report, so the dash stays quiet — when it is alive again, faults your truck already had will display. This is normal. Scan the vehicle for codes after install to see what is actually still there.
- ✔️ Replacement units must be programmed in the vehicle. This service covers hardware repair only — CPC4 programming is not included. If the unit you send is not original to your truck, it will need to be programmed to match your vehicle after install, done by a Detroit / Freightliner dealer or any shop with DDDL. Units original to the truck keep their existing programming and go back in plug and play.
- ✔️ Please select only the issues you are actually experiencing and describe the symptoms in your own words in the “Describe your issues” box.
- ✔️ If your part tests good and no fault is found, a $99.99 Bench Test / Diagnostic Fee may apply instead of the repair price.
- 💡️ Scan your vehicle for codes. If no codes are present, let us know. Any stored or pending codes help our technicians confirm the fault and avoid delays.

⚠️ If your CPC4 arrives with no communication, expect warning lights on the dash once the repaired module is reinstalled. While the module was dead it could not report anything, so the dash stayed quiet — that silence was the module, not a healthy truck. Now that it is communicating, faults your vehicle already had will display. This is normal and expected. Scan the vehicle for codes after install to determine what real faults remain.
✔️ Replacement units must be programmed in the vehicle. This repair service covers the hardware repair of your CPC4 — we repair the electronics inside the module and return it. CPC4 programming is not included with this service. If the unit you send us is not original to your truck, it will still need to be programmed to your vehicle’s parameters after it is installed. This is done in-vehicle by a Detroit / Freightliner dealer or an independent shop with Detroit Diesel Diagnostic Link (DDDL). If your unit is original to the truck, it retains its existing programming and goes back in plug and play.
ℹ️ Please describe the issues you are experiencing in your own words when placing your order so our technicians can diagnose your unit accurately.
ℹ️ If your part tests good and no fault is found, a $99.99 Bench Test / Diagnostic Fee may apply instead of the full repair price.
💡️ Scan your vehicle for codes. If no codes are present, let us know. Including any stored or pending codes helps our technicians avoid delays and confirm the fault.
A full diagnostic check should first be performed to eliminate all other possible causes for your symptoms, even if the symptoms match those specified on the common fault description.
If you send a unit in good working condition due to misdiagnosis, and our testing determines that there are no issues or faults with the unit, or if the part is beyond repair, then you will only be responsible for the shipping costs and a bench test fee of $69.99 may be applied.
IMPORTANT! If you are not sure that this part is the cause of the fault then we recommend that you do not go ahead with this purchase and instead seek further professional advice and diagnosis.See Why Our Customers Love UpFix!
