PR106
EFFECTIVE ENGINE TORQUE
Note:
Parameter PR106 "Effective engine torque" applies to the following sub-functions:
"Gear changes".
"Torque activation".
PARAMETER
DEFINITIONThis parameter indicates the effective engine torque in Nm. This signal is supplied to
the gearbox computer by the injection computer.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
No faults should be present or stored.
Conformity check with engine ignition on and engine running at idle speed.
