When bleeding the brake system after installing a new Four Wheel Anti-Lock Brake System (4WABS) Hydraulic Control Unit (HCU) or opening the HCU lines the process should start by cleaning all dirt from the brake master cylinder filler cap followed by filling the brake master cylinder reservoir with the specified brake fluid. A clear waste line needs installation on the RH rear bleeder screw with one end submerged in the recommended brake fluid solution contained inside a container. A technician should start the bleeder screw process by opening the RH rear until brake fluid streams from the valve while a helper applies pressure to the brake pedal before tightening the valve. Use the same procedure again until the fluid remains bubble-free while emptying the brake master cylinder reservoir when needed. To finish the bleeding process, first detach the waste line then follow the sequence of LH rear, RH front, and LH front bleeder screw procedures while flushing out the brake fluid through partially filled recommended brake fluid containers. You should connect the scan tool DCL cable adapter to the under-dash Data Link Connector (DLC) before following the scan tool instructions. The system bleed process should be performed according to earlier instructions.

Service of the front ABS sensor should start with removing the front disc brake rotor. Separate first the front ABS sensor wire from the front brake hose before disconnecting both the front ABS sensor electrical connector and wire. Unscrew the bolt that restricts the front ABS sensor and proceed to extract both the sensor along with its bolt. Reflection of the removal steps will install the components.

Begin servicing the rear ABS sensor by raising the vehicle until it can be supported. Cleaning the area surrounding the rear ABS sensor should be done prior to sensor extraction. Unplug the electrical connector of the rear ABS sensor, followed by unthreading its securing bolt, then extracting the sensor from the assembly. Complete the cleaning process on the mounting surface before checking for damage on the ABS sensor O-ring. Application of SAE-75W-140 High Performance Rear Axle Lubricant F1TZ-19580-B or equivalent fluid matching Ford WSL-M2C192-A specification is considered when the O-ring requires light lubrication. Reinstall the system by following the reverse order applied to removal.

You need to take off the front disc brake rotor to work on the Front ABS Sensor of E-250, E-350, and E-550 vehicles. Start by disconnecting the front ABS sensor wire from its connection to the front brake hose before unplugging the front ABS sensor electrical connector. Remove the bolt that secures the front ABS sensor in place before taking out the sensor. Rephrase these steps when installing the Front ABS Sensor.

Begin the brake system bleeding process after installing a new Four Wheel Anti-Lock Brake System (4WABS) Hydraulic Control Unit (HCU) or after opening the HCU lines by first cleansing the brake master cylinder filler cap and using the specified brake fluid to refill the reservoir. The waste line needs connection to the RH rear bleeder screw while its other end goes into a container containing partial recommended brake fluid. A helper should apply pedal pressure as you tighten the RH rear bleeder screw after it has produced a fluid stream from the opened screw. The bleeding process should continue until the fluid remains both transparent and without air bubbles followed by necessary brake master cylinder reservoir refilling. Follow the bleeder procedure by first tightening and then uncoupling the waste line on the RH rear bleeder screw and continue with bleeding the LH rear bleeder screw followed by the RH front disc brake caliper bleeder screw and then the LH front disc brake caliper bleeder screw. Use the scan tool DCL cable adapter to attach it to the vehicle data link connector (DLC) under the dash and execute the scan tool instructions. Implement the bleeding procedure once more according to the initial method.

Service of the rear ABS sensor begins with raising and securing the vehicle. You must wash away all dust and contaminants from near the back ABS sensor before taking it out. Next, disconnect the rear ABS sensor connector followed by removing its bolt to release the sensor. Before mounting the sensor, check the surface for cleanliness and examine the ABS sensor O-ring to detect damages. Lightly moisturize the O-ring with SAE-75W-140 High Performance Rear Axle Lubricant FITZ-19580-B that fulfills Ford specification WSL-M2C192-A or a product of equivalent quality. The sensor installation process ends by performing the reverse steps of sensor removal.

Starting the service of Electronic Brake Control Module needs users to disconnect the battery ground cable because static electrical charges can cause damage. First disconnect the instrument panel cluster panel before removing its electrical connector from the anti-lock brake control module. Complete the disconnection procedure then release the bolts which maintain the module and remove the anti-lock brake control module. Abnormal drive symptoms might appear due to adaptive strategy relearning after battery connection and reconnection since the vehicle needs multiple drives exceeding 16 km (10 mi). Use the same steps for installation of the anti-lock brake control module as the removal steps.

The service and repair of a Four Wheel Antilock Brake System (4WABS) Hydraulic Control Unit (HCU) begins with disconnecting the battery negative cable and the ABS module electrical connector after which vehicle operators need to take necessary measures to protect electronic modules from static electrical charges. Product label cautions and emergency medical help should be obtained from Ford/Motorcraft products by dialing 1-800-959-3673 in the USA or Canada. Consult the Material Safety Data Sheet (MSDS) to obtain further details about the product. Damages to painted as well as plastic surfaces will occur from brake fluid contact so immediately wash away exudations with water. The factory-made Ford authorized inlet hydraulic brake tubes serve this application purpose exclusively so only use these tubes for your brake system. Brake fluid spills can be avoided by installing a plug inside each open hydraulic brake tube port until they are disconnected. The hydraulic brake tubes should be disconnected followed by removal of bolts that secure both HCU and optional HCU bracket. The installation of the new HCU requires following the removal procedure steps in reverse order followed by brake system bleeding protocol.

A vehicle should be elevated while being supported as the first step for working on the rear ABS sensor. Wash off all dirt and debris surrounding the rear ABS sensor before starting the removal process. Unplug the electrical connector from the rear ABS sensor followed by removing its retaining bolt. Use a suitable cleaning method to complete the removal process by cleaning the sensor mounting area. A thorough inspection should be performed on the O-ring of the ABS sensor for damage after which gentle application of SAE-75W-140 High Performance Rear Axle Lubricant F1TZ-19580-B or an equivalent that fulfills Ford specification WSL-M2C192-A should follow.

The first step for servicing the rear ABS sensor requires raising the vehicle before performing support. The service team should clean away dust and debris before unmounting the rear ABS sensor. Detach the electrical connector of the rear ABS sensor before replacing the sensor by removing its securing bolt. The technician should clean the mounting area after removal before checking the O-ring for damage. When the O-ring shows no damage, you can lubricate it using either SAE-75W-140 High Performance Rear Axle Lubricant FITZ-19580-B or an equivalent product that complies with Ford specification WSL-M2CI92-A. Reinstallation of the rear ABS sensor requires following the reverse steps of removal.

First, service and repair procedures for the front ABS sensor start with following the removal sequence illustrated below. Follow the removal order to install the new sensor according to its reverse sequence. Local surface areas should be completely cleaned before installation while the anti-lock brake sensor O-ring must be checked for damage.

The first step for Electronic Brake Control Module servicing requires grounding out the battery cable. Pay close attention to an illustration and table before removing parts in the indicated sequence. Complete component installation occurs by putting them back in the opposite sequence to which removal occurred.
