How to reset scr system fault

Fault codes associated with Selective Catalyst Reduction (SCR) NOx efficiency low are the most dreaded codes you will find on the Detroit Diesel application and can drive your costs high. Long story short, these fault codes mean that the efficiency in the aftertreatment system, aka the 1-Box, is not operating within the required threshold (70%).

A system and method of inducing proper operation of a diesel engine exhaust after-treatment system employing SCR technology monitors components to detect a fault condition representing one of a DEF level fault, a DEF quality fault, and a tampering fault, activates a trigger event indicator in response to detecting the fault condition. The trigger …Not only the often and unexpected SCR system repairs are costly, but the physical removal of the SCR components. This also causes a fault with the system. Our John Deere SCR (AdBlue) removal via online ECU remapping will save you from unexpected repairs and overhead costs. Longer engine life.
