07 Chevy express when blower motor is in operation with highest setting, ABS and parking brake light's come on with ringing tone Code U1041 showed up on obd scanner What is possible cause? Thanks


Sounds like a network communication issue.
Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module receives a message for a critical operating parameter, the module records the identification number of the module which sent the message for state of health monitoring/node alive messages. A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. Once an identification number is learned by a module, it will monitor for that modules node alive message. Each module on the class 2 serial data circuit is required to send a Node Alive message every 2 seconds . When no message is detected from a learned identification number for 5 seconds , a DTC U1???.
??? is equal to the 3 digit identification number of the module. Control Module ID = BCM
I would start checking ALL ground wires/straps on this vehicle. That has been a problem with GM. Try clearing the code and see if it comes back after you clean ground connections.

U1041 code


That code means the abs is not talking to the pcm on GM vehicles but since you did not post the year make and model, there is no way to tell for sure.

How do I fix ? DTC code u1041 lost communications with chassis multiple control system


The BCM talks to the ECM and they are not talking. IT could be the cable or one of the computers is bad.

Obd code U1041


Codes U1XXX (where XXX stands for several possible numerical digits, 001 - 254) are communications fault codes. The first part (U1) tells you that there is a communication problem with one of your many onboard control modules. The second part (XXX) or in your case, (041) tells you which module is not communicating. It can vary from year to year, model to model. so without knowing the year and model of the vehicle we are talking about, I cannot tell you which one.

In any case, there is a module that is not communicating with the other modules that are sharing information through the Class 2 serial data circuit. One module uses U-codes to tell on the other modules. For instance, If you got the U1041 code out of scanning the Engine Control Module, you can bet that the Engine Control Module is not having a problem communicating. If it was, you would get a non-communication fault from your scan equipment and the ECM would not tell you anything. Instead, the ECM is telling on the module that is not communicating properly .

I like to call these codes the 1-800 codes...THE PHONE LINE IS DOWN... lol ;)

Trouble codes P0128, P0455 and U1041


P0128 is the coolant is below normal temperature.
P0455 is Evap system detects a large leak.
U1041 is communication was lost to brake control module.
It is weird that you are having these problems at the same time.
You may not have a problem in anyone of these systems. But again you may.I would suggest that you look into the battery, related wiring, connections, and the alternator. If the electronics are not getting enough voltage then you can have system failure.
