  Q: How to replace the ABS Control Module in the Antilock Brake System on Scion xA?

  A:

  The Brake Actuator Assembly change for Antilock Brake system starts by draining brake fluid followed by cleaning off fluid which reaches painted surfaces. Start by removing the battery then disconnect the brake actuator and bracket by unlatching the connector while employing Special Service Tool: 09023-00100 to detach the 6 brake lines and note their positions for subsequent reconnection. To extract the brake actuator with bracket you must remove three bolts. After that you should eliminate the two nuts to attain separate components. Begin installation by attaching the brake actuator to the bracket on which you should secure it with 2 nuts tightened to 5.4 Nm (55 kgf-cm, 48 inch lbs.). Then install the actuator with bracket using 3 bolts torqued to 19 Nm (194 kgf-cm, 14 ft. lbs.). Connect the actuator connector by attaching each of the 6 brake lines to their proper places on the brake actuator while ensuring a torque measure of 15 Nm (155 kgf-cm, 11 ft. lbs.). The battery installation process requires filling the brake fluid reservoir followed by bleeding the master cylinder with Special Service Tool: 09023-00100 and then bleeding the brake lines. End the repair process by monitoring the brake fluid level in the reservoir followed by checking for brake fluid leakage then testing the brake actuator using a hand-held tester.

  Q: How to service and repair the ABS Control Module for Antilock Brakes on Scion xA?

  A:

  Services and repairs of the Hydraulic Control Assembly for Antilock Brakes should begin by disconnecting the negative battery cable then allowing 90 seconds of waiting before continuing due to Air Bag and seat belt pretensioner activation prevention. The service requires removing all brake fluid while cleaning painted components with any fluid contact. Service technicians must start by releasing the latch of the actuator connector to disconnect it then they should use Special Service Tool: 09023-00101 to detach the 6 brake lines from the brake actuator before marking or tagging each line for returning them to their original positions. The process to separate the brake actuator and bracket begins by removing three bolts then continuing with removing two nuts. Begin the installation process by connecting the brake actuator to the bracket with 2 nuts then torque them to 5.4 N.m (55 kgf.cm, 48 in.lbf). Next mount the brake actuator with bracket to the vehicle using 3 bolts whose final torque value stands at 19 N.m (194 kgf.cm, 14 ft.lbf). Install the brake actuator lines at their designated positions on the actuator unit by using a torque wrench having a 30 cm (11.81 in.) length with a fulcrum of 15 N.m (155 kgf.cm, 11 ft.lbf) torque unless using the Special Service Tool or 14 N.m (143 kgf.cm, 10 ft.lbf) torque with its assistance. After connection of the brake actuator connector place brake fluid in the reservoir while performing brake fluid bleeding on the Brake Master Cylinder brake line and brake actuator through the VSC system. Clear any brake fluid leakage from the reservoir then you should check its level before reattaching the cable to the battery terminal. After reattaching the negative battery terminal it is necessary to check the brake actuator through the intelligent tester while completing an initialization sequence because this process affects certain system functionality.
