2900 SPN Fault Code

Name:

Transmission Engine Crank Enable

Description:

State signal from the transmission indicating if the transmission�s status is such that engine cranking is allowed (i.e. at a minimum, transmission is in neutral and the driveline is disengaged). As sender of this information, the transmission is responsible for correct indication immediately upon first broadcast of this parameter.As with hard-wired neutral start implementations, those utilizing this parameter should consider the impact of the transmission or other controllers �resetting� due to voltage drops during the engine start sequence. The vehicle system design should also consider the impact of timing latency in the engine starting sequence. For example, the turn of an ignition key from �off� to �start� may happen more quickly than the transmission controller can boot up, determine its� current state of being, and begin broadcasting information over the J1939 datalink. 00b = Cranking disabled; engine cranking is prohibited by the transmission 01b = Cranking enabled; engine cran

2900 spn fault code name is Transmission Engine Crank Enable. If you don't take the time to look into 2900 spn fault when it arises, it can add up quickly. One small issue like 2900 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 2900 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.
