1845 SPN Fault Code

Name:

Transmission Torque Limit

Description:

Parameter provided to the engine from the transmission as a torque limit to be invoked by the engine in the event that J1939 communication with the transmission is lost.The intention is to protect transmissions that use a continuous torque limit during torque converter mode or operation in specific lower gears, where stall or drivetrain torque may reach levels higher than the gearbox capacity. If communication is lost during torque limited operation, unrestricted engine torque output could harm the transmission. 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 a torque limit holding the engine to less than or equal to the value of the Transmission Torque Limit parameter. The engine may release the limit when transmission-to-engine communication is re-established. A value of FF00h to FFFFh indi

1845 spn fault code name is Transmission Torque Limit. If you don't take the time to look into 1845 spn fault when it arises, it can add up quickly. One small issue like 1845 can cause a larger component to become damaged without taking the time to investigate. If you suspect your truck is suffering from one of these issues, look into replacing those small components to save money down the road.

Note: The name and description of 1845 code represents text descriptions for faults supported by another coding system and does not necessarily comply with SAE J1939. For a specific engine manufacturer's explanation for codes, please consult the engine's technical manual. See also other spn codes.
