The DTC Cleaner can be helpful when the driver needs to erase faults on the go due to faulty vehicle components. It does not need any diagnostics knowledge to use as it simply plugs in and does the job for the driver.
For example, faults in the SCR system typically leave the driver with a capped vehicle (Limp mode) after a set amount of time (stuck on one gear with a maximum speed of 15-30 mph, sluggish with a heavy load).
Our DTC Cleaner can reset the Limp mode timer for the vehicle, which lets the driver finish his duties and also drive to servicing quick and easy. If you cannot afford an SCR repair immediately then it is also not an issue: you can use the DTC Cleaner as many times as you wish before finally committing to the repair of the SCR system.
