Re: ABS Sensor Problem???
I own a 2006 Equinox LS AWD. I experienced the same concern with the ABS activating during low speed braking, but it took a long time to set a trouble code (the ABS/TC warning lamps did not come on for a long time, and when the finally did they would only come on briefly then go out). The code set for a LF speed sensor fault. I replaced the LF wheel hub & sensor assembly with an aftermarket part. The code cleared out but it continued to cause ABS activation at low speed. Watching the speed signals with a scan tool while driving, it showed all four sensors reading properly but indicating that the vehicle speed was exactly 2X what the actual speed was (60 mph read as 120 mph). Still no codes no lights. Thinking the EBCM may have a fault, installed a new EBCM, but problems persisted. Finally observed LF speed sensor signal drop out, so thinking had defective hub/sensor replaced with another aftermarket. This one was even worse. Finally replaced with genuine gm part (which strangely enough had the exact same markings as the two previouse aftermarket parts) and knock on wood no problems since. But scan tool still shows that speed sensors showing vehicle speed as 2X actual. Don't suspect faulty VSS at transfercase because speedo is reading correct. Anyone else experience this?
