Description
DTC Off & Check Engine Light Off Service
Our DTC Off service helps disable selected diagnostic trouble codes from your ECU / ECM / PCM software. This service is commonly used when a fault code keeps triggering a check engine light after repairs, modifications, or off-road vehicle use.
What is DTC Off?
Professional DTC Off programming removes or disables specific trouble codes inside the ECU software. This can help prevent selected fault codes from turning on the check engine light when the related system is no longer required or has been modified.
This service can help with:
Check engine light removal
Specific DTC / fault code disable
ECU / ECM / PCM software modification
Off-road and motorsport vehicle applications
Important Note
DTC Off does not repair mechanical or electrical problems. If the vehicle has wiring issues, sensor problems, or damaged components, those problems should be diagnosed first.
This service is intended for off-road, motorsport, and competition use only. Customers are responsible for making sure their vehicle complies with local laws and regulations.
Turnaround Time
Average processing time is 1 business day once we receive your ECU file or module.
Remote file service and international shipping are available.
How It Works:
After purchase, send us your ECU file or ship your ECU / ECM / PCM module to us.
Please include the vehicle information, ECU part number, and the DTC codes you want removed.
Once we receive your file or module, we’ll modify the software and complete the DTC Off programming.
After the service is completed, we’ll send the modified file back or ship the programmed module back to you.
