Customer Question

i have a 2006 buick terraza with C0045 Rear left abs sensor circuit, i changed the whole hub bearing, i checked wires from EBCM (Pin 12 and 13) to connection C305 they are GOOD, and checked for short wires from C305 to rear left sensor they are GOOD, i tried to erase the code after all the job, and ABS LIGHT C0045 still here, i need to get inspection asap.

If continuity is good between the ebcm and c305 terminals 12 to d and 13 to c, check for continuity from c305 to speed sensor, it's good you have a bad ebcm if you don't have continuity then repair are replace that wire.
