abs/antiskid/traction lights on no codes

My lights are on, no codes read. no check engine light. even when I disconnect the battery. and then reconnect, the lights are on as soon as the key is turned back on without even driving it. all sensors have been replaced. no change. no fuses blown. any ideas where to get troubleshooting info on this truck?


thanks

 

Sounds like you should bring it to the dealer, see if there is something they can read that you can't pull with a standard obd ii code reader.
