• Q: How to service and repair the ABS Control Module for Antilock Brakes on 2005 Toyota Sequoia?

  A: The first step for Hydraulic Control Assembly Antilock Brake servicing involves disconnecting the connector through puller manipulation of the release bar. Follow the sequence stated on Special Service Tool 09023-00100 and 09023-38200 to disconnect the 6 brake lines from the actuator assembly using a combination of 10 mm nuts torqued to 15 Nm (155 kgf-cm, 11 ft. lbs.) and 12 mm nuts torqued to 19.5 Nm (195 kgf-cm, 14 ft. lbs.). Before reinstallation it is critical to either mark the brake line connections with tags or create a memo to note their locations. Take off the actuator assembly by removing three nuts which should be torqued to 11 Nm (112 kgf-cm, 8 ft. lbs.). The actuator bracket needs loose bolts with 9.5 Nm (97 kgf-cm, 84 inch lbs.) torque before extracting the 3 cushions from the bracket. Move onto the next step by employing an E5 torx wrench to remove the 3 screws fixed to the skid control ECU which need to be torqued at 1.8 Nm (18 kgf-cm, 16 inch lbs.). The actuator needs protection against environmental particles which could contaminate the sealing surface; plastic tools or soft materials should be used to clean it without chemical solutions. Reverse step-wise order of disassembly and removal procedures should be used during product reassembly and installation execution. It is necessary to fill the brake reservoir with brake fluid before bleeding the brake system when checking for any potential leaks. When replacing the skid control ECU it is necessary to execute zero-point calibration operations for steering angle and master cylinder pressure sensors alongside the yaw rate and deceleration sensors.
