No communication with ABS was created by Michtom
2008 Buick LaCrosse 3800. Intermittent no traction control message on, I haven’t seen an ABS light. U1016 for ABS module and U1040 for IPC. I am unable to read data from the ABS module but, seems to work on gravel road. All wheel speed sensors tested good. Powers and grounds tested good at ABS module. Replaced ABS module with a used one with no change. I have continuity from ABS module to data splice connector. Can anyone give me some direction.
