DEF is a diesel exhaust fluid consumed in vehicles with Selective Catalytic Reduction (SCR) technology to reduce harmful gases being released into the atmosphere.

TIC Description

Further Detail

O

DEF is a 32,5 % solution of high-purity, synthetically manufactured urea in de-mineralized water. It is a safe-to-use fluid.

DEF used to follow ISO 22241 (ISO 22241-1, ISO 22241-2, ISO 22241-3). This international standard protects your vehicle from contamination which could cause serious damage.

SPN: the practical way to define the combination of the concept with observed properties is through SPN J1939 definition.

che.powersource.def.volume.liter: 0.12 = SPN5963 Aggregated value of def flow during a period of time defined in the header
