Please note that we do not offer Refunds for Repair and Rebuild Services or Programming / Cloning Services. Our Technicians replace parts and dedicate man-hours based on the problem description and/or diagnostic trouble codes provided. 

SERVICE TURN-AROUND TIMES All Services have a turnaround time of 3 to 5 business days (unless otherwise specified), and your service will not commence until all requested information and ECU (Electronic Control Unit) (Electronic Control Unit) are received. These times do not include Shipping Time. It is your responsibility to provide the necessary information, as ACS will not repeatedly request it.

• Remanufacture Service: 3 to 5 Business days
• Programming / Cloning: 1 to 3 Business Days
• Harness Restoration: 5 to 10 Business Days
• 24-Hour Service Guarantee: Our 24-Hour Service ensures that your ECU will be Tested and Repaired within 24 hours of receiving the unit, excluding holidays and weekends. Please note that Shipping Time is not included in this guarantee.

While we strive to meet these deadlines for the majority of our services, we cannot guarantee them due to potential delays beyond our control. We will make every effort to communicate any delays to you promptly. It is advisable to allow for a few extra days in your planning.

SERVICE Please be advised that ACS does not diagnose your Unit; we specialize in Testing and Repairing the specific issues that you provide. We rely heavily on your diagnoses. All information must be accurately and thoroughly provided to facilitate proper Service for your unit. In the event that notes are lacking in specificity and detail, ACS will only be able to replace the unit and refunds will not be issued.

Before sending in your unit, please ensure that you scan it and provide ACS with information regarding your communication with the ECU (Electronic Control Unit). Please indicate whether you have Communication with the ECU (Electronic Control Unit) or if you are experiencing No Communication and cannot read the ECU (Electronic Control Unit). If you have Communication, please provide the DTCs present, including the DTC number only (e.g., PXXXX). 

It is necessary to remove any Aftermarket Performance Tunes from the ECU (Electronic Control Unit) before sending it in for service. During the Testing, Repair and Rebuild process, Software Updates or Reflashing of the unit may be required, resulting in the loss of all Aftermarket Performance Tunes. ACS cannot be held responsible for any lost Aftermarket Performance Tunes.

Upon receiving your ECU (Electronic Control Unit) (Electronic Control Unit) and Service Form, ACS will initiate the testing process for your unit. It is important to note that all services are subject to a test fee at minimum. If you have already prepaid for your service, any excess amount will be refunded to you accordingly. Test Fees listed below:

• Gas: $88.88
• Light and Medium Duty Diesel: $148.88 to $248.88
• Heavy Duty Diesel: $248.88 to $448.88

If your initial concern was No Communication, once you receive the ECU (Electronic Control Unit) back and Communication has been established, you may encounter DTCs (Diagnostic Trouble Codes) upon installation of the unit. These are not new issues; they were simply not visible because of the inability to connect with the unit (lack of Communication). Please note that ACS is not liable for these issues. 

• In the event that this occurs, kindly uninstall the ECU (Electronic Control Unit) to avoid any additional damage and promptly notify us by responding to your Service Notes with a list of all current DTCs and a brief description of your issues. Subsequently, we will reach out to you with further instructions.

If, for any reason, you install the unit and it is not functioning correctly, please pause and scan the unit. Once the Unit has been scanned, please uninstall the ECU (Electronic Control Unit) to avoid any additional damage. Subsequently, email us your scan results. We will promptly reach out to you and provide guidance on the next steps.

GENERAL It is important to note that simply Replacing, Rebuilding, or Programming an ECU (Electronic Control Unit) may not resolve all vehicle faults. The process of Rebuilding, Replacing, or Programming an ECU (Electronic Control Unit) must be accompanied by thorough vehicle Diagnostics and Repairs. It is crucial that all vehicle faults are addressed before installing a Rebuilt, Replaced, or Programmed ECU (Electronic Control Unit) or risk damaging the ECU (Electronic Control Unit).
