2007 HD x883xl low with U1064 Loss of TSM/FSFM Serial Data to ECM. What does that mean and how can I fix it please?


U codes are lost communications between computers. You changed the battery or unplugged something, so it happened. First thing I do is erase the codes. If they come back. wire chasing., then diagnose a bad computer. It happens. I don't work on HD's, but I do electronics. Only guessing, but probably the ignition control module. Could be a crank sensor, if it has one. I work on cars and trucks. All of them.

I have a Pontiac grand am 2000 I'm getting codes u1000 and u1064


U1000 means modules on the data line have stopped seeing communication with a module. U1064 is a communication code for the BCM. It may be faulty or not communicating for some reason. If it has been changed it needs to be programmed.

Check engine light codes


the c0899 is a low battery voltage and the u1064 means communication is lost with the bBody Control Module. The u1026 is also a communication problem and the p0449 is an emissions problem, around the venting of the fuel tank. Sounds like several different unrelated problems.

What do these check engine light codes mean? I can't find them anywhere. B0040, B0099, U1026, U1064


As previous post stated you may have data cable unhooked somewhere.
B0040- Second Row Right Frontal Stage 2 Deployment Control (Subfault)
B0099- Right Frontal Restraints Sensor 2 (subfault)
U1026- Loss of Active Transfer Case Control Module Communications.
U1064- I do not have a listing for that code on hand. May be able to obtain it when I get to my shop tomorrow.

U1064 code & can't check the codes on a scanner. engine starts & dies. when it was running the abs light & brake lights were on & theft & service lights were on.


Sounds like a blown fuse to one of the computers, either the ECM (engine control computer) or the BCM (body control computer). The ECM fuse should be under the hood and the BCM fuse in the cabin. The U1064 means a loss of communication on the data line between computers (64 usually is the BCM). If the computers can't communicate they will shut down the engine and set trouble codes. The other issue could be a faulty ignition switch not allowing power to a computer (but not common for cavaliers or sunfires). If fuses are good, chances are you have a faulty computer somewhere in the data line, shorting out communication.
