We offer you the option of "DTC Off" in the file service. What does DTC OFF mean? DTC Off stands for "Diagnostic Trouble Code Off", which means that the monitoring function for certain error codes (P-codes) in a vehicle has been switched off and it can no longer intervene in the engine control system. Advantages: - DTC Off can be useful when encountering a trouble code that is preventing the vehicle from functioning. Disabling the code may allow the vehicle to function normally again. - Some performance upgrades or conversions to a vehicle can cause trouble codes to appear that operate the vehicle in limp home mode. Disabling these codes will allow the vehicle to function normally. Disadvantages: - Disabling trouble codes can result in not detecting and fixing the actual problem in the vehicle, which can lead to further damage in the long run. - It is illegal to intentionally disable the trouble code monitoring feature in order to get a vehicle through an emissions or safety inspection. - DTC Off can also result in the vehicle not meeting required emissions or safety standards, which could result in fines or other penalties.
