The abs self test pump activates once after a short distance of driving. Aftera longer drive, it engaged a few times then the abs service light and tractionlight came on. Shut off the car turn it back, went away then came back. Readonline sometimes it glitches.
Its coming on regularly now, and sometimes before the lights come on, doing aregular stop the brake pedal pulsates, like the abs activating at low speedthen the lights come on. Both the abs and traction control don't work.
tried a regular obd ii scanner can't scan the codes, has to be abs scanner,checked brake fluid level its okay.
Read online that sometimes its the contacts of the speed sensors, or wiresfrayed going to the wheel hubs sensor integrated into the hub .
Sometimes its the wheel hub.
It could also one day taking the wheels off and examining the wiresclosely even disconnecting the connectors and applying grease if we have any.
Could look at the abs control module connector.
Last year we changed the tie rod ends and the driver side front wheelhub.
other thing, when we put the summer tires on, one of the sensors wasn't readingprobably due to low battery as its the originals on there.
The tire pressure sensor light turned on, just like in winter time so that'sokay. But now I notice that is not coming on, only the abs and service light, now the tire pressure light is on too.
it seems to be very hard to come by a scanner that can scan the abs codes. Unless anyone has any ideas please.
thank you
