GMC GENERAL 4191 SPN Fault Code

Name:

Engine Requested Torque (Fractional)

Description:

This parameter displays an additional torque in percent of the reference engine torque. When the MSB is set to 1, this parameter is not available. When the MSB is set to 0, bits 1 to 3 indicate the desired torque with resolution of 0.125%/bit . Range is from 0 to 0.875% of reference torque. The parameter is used in combination with SPN 518 Engine Requested Torque/Torque Limit. The resulting torque/torque limit will be calculated by adding these two parameters. Validity of Engine Requested Torque High Res has no effect on SPN 518. Additional torque representations 0000b = +0.000% 0001b = +0.125% . . . 0111b = +0.875% 1000b to 1111b = not available For example, if SPN 518 = 150 (or 25%) and this parameter is 0100b, the torque would be 25.5%. If SPN 518 = 175 (or 50%) and this parameter is 0001b, the torque would be 50.125% If SPN 518 = 175 (or 50%) and this parameter is 1111b, the torque would remain 50% (no high resolution available)
