  Q: How to remove the ABS Control Module for Antilock Brakes on Scion xD?

  A:

  Brake fluid draining represents the starting point for Hydraulic Control Assembly for Antilock Brakes removal which requires cleaning all affected painted areas of brake fluid residue. Begin by taking out the cowl top ventilator louver center as well as the battery followed by battery tray the battery carrier. This procedure does not include VSC systems so first release the lock lever and disconnect the brake actuator connector yet avoid letting brake fluid enter the connector. A union nut wrench helps detach 6 brake tubes from the brake actuator while labeling tubes for reinstallation; 1: Front wheel cylinder RH, 2: Front wheel cylinder LH, 3: Rear wheel cylinder RH, 4: Rear wheel cylinder LH, 5: 1st master cylinder, 6: 2nd master cylinder. Detach the brake actuator with bracket by removing the 3 bolts but avoid breaking the brake tubes or wire harness. Detach the actuator brackets by removing 3 bolts on both brake actuator assemblies with VSC. The initial procedures for separating brake tubes as well as disconnecting the actuator connector remain the same. Three bolts need to be removed to uninstall the brake actuator bracket assembly without VSC but four bolts need to be removed when dealing with the assembly that includes VSC functions.

  Q: How to install the ABS Control Module and connect the brake tubes on Scion xD?

  A:

  The installation of the brake actuator bracket assembly requires 4 bolts to be fastened at 5.4 Nm (55 kgf-cm, 48 in-lbf) torque while maintaining the hole plug in place before connecting the brake tube because new actuators contain brake fluid and never pull on the connector section. The installation process begins with attaching the brake actuator onto the bracket through 3 bolts which need to be tightened to 19 Nm (194 kgf-cm, 14 ft-lbf). Users must exercise caution to avoid damaging brake tubes or wire harnesses during this operation. The brake tubes should be temporarily placed on the brake actuator according to this sequence: 1: front wheel cylinder RH, 2: front wheel cylinder LH, 3: rear wheel cylinder RH, 4: rear wheel cylinder LH, 5: 1st master cylinder, 6: 2nd master cylinder. The brake tubes should be installed on the brake actuator through the use of a union nut wrench following a torque setting at 15 Nm (155 kgf-cm, 11 ft-lbf) with or without the wrench based on the 300 mm (11.8 in.) and 22 mm (0.866 in.) fulcrum length requirements of the torque wrench and the 22 mm (0.866 in.) union torques while keeping both wrenches parallel to each other. Securely join the brake actuator connector by achieving proper connection while blocking water and oil as well as dirt from entering. After the installation of the battery carrier and tray with battery in place follow the procedure of filling the fluid reservoir then bleeding the master cylinder together with the Brake Line and actuator before checking the reservoir fluids levels and inspecting for brake fluid leaks. The installation of cowl top ventilator louver center must be completed followed by checking the actuator with Techstream. Additionally, the zero point calibration of yaw rate and acceleration sensors needs to be performed along with a DTC check.
