Mack MD742 7827 SPN Fault Code

Name:

Transmission Communications Failure Idle Torque Limit

Description:

This parameter is provided to the engine from the transmission as an idle governor torque limit to be invoked by the engine in the event that CAN communication with the transmission is lost.The data is transmitted in indicated torque as a percent of reference engine torque (see the engine configuration message, PGN 65251). The percent torque value will not be less than zero and it includes the torque developed in the cylinders required to overcome friction. Please note that the � Transmission Communications Failure Idle Torque Limit � only applies to the engine�s idle governor. It does not alter the engine�s torque map. Full accelerator torque and other similar torque requests are still allowed to access the full torque map. It is recommended that engines use reception of the ETC#1 message as a transmission � heartbeat �. In the event that the ETC#1 message is not received in a time period of 5 times its� broadcast rate (5 x 10 ms = 50 ms), the engine should invoke the last received id
