Question

I have a code, u0401 and am having a hard time finding definition or what it pertains to. There is a esp/abs light on I believe. The scanner states implausible info from ecm/pcm. any help would be great.

Answer 1

U0401 Implausible data received from ECM / PCM

This code will set if there is a DTC (diagnostic trouble code ) which will cause the ABS system to shut down this is for safety, the reason the vehicle is not a manufacture specifications. If there is no DTC from either the engine management or the transmission system , then you are dealing with a fault in the ABS module, you need to perform a  ABS verification test with a scan tool that can retrieve ABS data and codes.
