My Answer is based on clues, symptoms and info in your question. Please include everything. Thanks
If you have the RWAL system (rear wheel anti-lock) that e says there's an open in the speed sensor circuit or faulty speedometer.If you have the 4WAL system....That code doesnt exist...lolBut anyways, to clear the codes on the RWAL, remove the brake fuse for 5 secs and then reinstall it.
If it comes back its the speed sensor or speedometer
How can the speed sensor give a brake code? This light has been on about a month.
Sorry I did not respond earlier but our internet has been down. I know exactly where the speed sensor is located and will replace. But why would the brake light come on it being a speed sensor issue, just curious. Seems weird.
The brake light may be another issue the brake light blinking 9 times and nine times is a blink code describing abs fault. I would check for leaks and soft pedal and for any hydraulic issues.
Thanks and let me know of any other questions you may have.
