Help DTC code C1281 thrown
Can anyone help with code C1281? I've got the diagrams and the troubleshooting worksheet for this code from GM, but there could be 5 to 9 different things causing this code and hours of testing... Anyone have this code and fix it??

This code is related to the EBTCM. It is known to have ground issues. There is a ground lug on the EBTCM motor that can get corroded and cause weird issues.
Read the resistance of the EBTCM to Chassis ground. It should be ZERO +- .02 OHMS
Take the reading and let me know what you get.
