Changsha Huaxing car repair shop Mr. Cheng: 13908462346 Tang: 13707480626 Website:? Http: //www.huaxingqx.com/ Address:? Furong District lofty Road Ma Poling (Mapo Road Primary School opposite) Where Changsha a car with a mileage of about 74000KM maintenance FAW Toyota Reiz sedans. It reflects the owner: The car electric power steering suddenly failed, the steering wheel does not help. After the pick, the inquiry learned that this car steering in the process of moving a sudden lack of power steering, fault indicator lights, turn the steering wheel feels very heavy, so the repair shop for inspection. Connection diagnostic query DTCs, showed three fault codes are stored in the steering ECU among its DTCs were C1511, C1516, C1526. C1511 fault meaning torque sensor is abnormal, C1516 meaning of the torque sensor initialization unfinished, C1526 meaning of the steering angle sensor initialization incomplete. These three fault codes recorded, then perform the clear fault codes, found C1511 can be cleaned, the remaining two can not afford to clear the fault code, indicating a need to learn. Perform device inside the steering angle sensor learning and torque sensor learning. In the learning process, still can not complete the learning step. Read fault codes again found fault code C1511 again, the storage system due to sensor error fault code can not complete school where learning Changsha car maintenance operations, it seems torque sensor is really a problem. Below, a brief introduction of this car torque sensor. Since Reiz car uses electric power steering system, the steering torque sensor is located on the portion of the machine. Torque sensor rod torsional deformation by checking reverse and convert to EPS ECU pass underneath the battery into an electrical signal. By the phase sensor unit 1 and 2 and torsion rods, located in the steering shaft sensor 1, sensor 2 is located in the pinion shaft, torsion bar is rotated so that its rear two phase separator unit generates a relative angle, and converted to a voltage signal is passed EPS ECU, EPSECU decided EPS electromechanical steering unit to provide the appropriate operating voltage based on the relative position of these two units. According to the meaning of this fault code point torque sensor, as part of ECU rare problem, first check the corresponding line control circuit diagram of the seven lines of the torque sensor to measure EUC partial one, no problem, indicating that the line is no problem. Problems may arise in the torque sensor, since the torque sensor can not be replaced individually, it can only replace the steering problem. After replacement, and by steering angle sensor device and the torque sensor initialization learning, fault LED is off, the electric power steering system back to normal. Changsha where car maintenance EPS ECU initialization: Connect diagnostic socket 4 feet and 12 feet CG terminals, TS 13 feet, TC terminal and the ignition switch is turned to the ON position, opening and closing the TC terminals in the 20s 20 times, to ensure that electronic power steering indicator shows, when the ignition is switched off. Then set the steering angle sensor, follow these steps: After connecting CG terminals and TS terminal, turn the ignition switch to the ON position, the steering wheel to the left 45 °, back positive, then to the right 45 °, back to the positive, provided set the steering angle sensor. After setting the steering angle sensor, TC terminals connected again to determine the light is flashing, then disconnect the cable, and turn the ignition switch to the OFF position, complete the study. I hope no diagnostic manual learning method to help service personnel. Changsha where car maintenance
