My vsc off, vsc trac, skid control, brake and abs light were all on on my Toyota Sequia. Dealer had me replace the skid control ecu. The codes (c1203, c1223 & c1241) are gone/clear and the the vsc off, vsc trac and abs light are still on. The brake and skid control went off. The dealer says it is now showing a code stating that it needs zero point calibration, the problem is it wont take it, they have tried a couple times and it will not work. They are telling me they need to tear the dash apart and start to ping and try and find the problem....this could get very expensive!

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd Megan, If they replaced the Skid control engine control unit or computer and it's not working - 'THEY' need to figure it. It should not cost you anything. You could take it to another dealer to get a second opinion
