Okay, replaced YAW sensor. Cleaned and reconnected wiring on ABS and ECU. Checked wiring under right side of interior dash. Checked wiring under fuse box. OBD2 reader shows TCM module " p0600 IC instrument cluster can message incorrect" and P0600 "IC HVAC can message missing" . ESP module shows all kinds of errors, steering angle sensor missing, CAN malfunction YAW reading, NO steering angle message, PCM coding incorrect, CAN malfunction renote sensor cluster, LF and RF wheel sensor failure , Steering angle sensor malfunction. Tach, Speedometer and Engine temp gauges all pulse and off. Brake, BAS and ESP flash sporadically. Rad fluid level flashes, Brake wear indicator flashes. High speed fan does not come on after starting car but does come on and stays on after driving a few minutes. Any suggestions would be appreciated.
