Todd71106 Posted November 2, 2021 Share Posted November 2, 2021 I just purchased a 2013 Mack Granite GU 713 MP8. The previous owner cut the wires leading to the Yaw Sensor and capped them off. I believe the Yaw sensor is causing the ABS Code MID 136 SID 103 FMI 9 136: ABS Wheel Speed Sensor, 103: Yaw Rate Sensor, 9 abnormal update rate. That combined with a MID 136 SID 4 FMI 14 136: ABS Wheel Speed Sensor, 4: Drive Front (R) 2 14: Special instructions Those are the only 2 ABS codes i have. They did the same with the fuel filter wires. That just gives me a Guard Dog Message to check the Fuel Filter. The truck runs and drives fine. Just wondering if it is going to cause any other problems if i can't fix it right away.
