Hello bry 9477, the flash out code 9 indicates that you have excessive resistance in the circuit from the rear differential speed sensor, The code take us to a very length test to verify the circuitry to and from the sensor, and also proves out the rabs module. I have seen many of these over the years and every one of them has turned out the be the sensor in the rear axle. The part is approx. $35.00 and will take all of 10 minutes to replace.
