ABS fault

Start the car, hdc light goes out, tc and abs light stay on, travel down the road, hdc light comes back on. Replaced hdc switch, replaced o/s front abs sensor which had a damaged wire, brake light switch seems ok, getting readings between 10 and 20 000 ohms, [ I think] from all four abs sensors, Any tips anyone.

Currently has no mot or tax, just got to get the abs and the smokey exhaust sorted so I can send it for mot.

You need to get the codes read in the abs computer to find out what is happening. Could be a number of faults.

ABS = yellow
ETC = yellow
HDC fail = yellow
HDC information = green

Got that lined up, but not sure if the codes will still be there, battery was off the vehicle for a good while.

Anyone know if stored fault codes remain, if the battery is disconnected?
