Once the wheels are bled bleed the modulator. Care should be taken not to get brake fluid on the motor pack.

Install bench bleeding kit into LF & RR outlets and place tubes in reservoir. The outlet lines of the modulator are marked on the motor pack (See Figure 10). Mount assembly in vise and fill reservoir with DOT 3 fluid from a sealed container. Use the following steps to bench bleed the assembly: Caution should be used because once the rear pistons are homed, the rear wheel circuits are added back into the system and if air is present, expect a low pedal.Д«leeding should start with bench bleeding the master cylinder/modulator assembly. Once the pedal is firm, test drive the vehicle above 4 mph and the ECU will self test which includes homing the pistons. If the rear pistons are not in their homed position, the front wheel circuits can be bled until a firm pedal is obtained. The other method should only be used when necessary. The first is to use a bi-directional scan tool, such as the Tech 1 or 2, to command the rear circuit motor to home the piston. There are two other methods of homing the rear circuit pistons. Making sure the pistons are in the home position ensures that the fluid path to the rear brakes is open to allow bleeding the system without a scan tool (See Figure 9). This step is not that important for the front circuits, but is critical for the rears (center gear). This places all of the pistons in what is referred to as the home position. It is important before installing the motor pack to rotate the gears on the modulator in a counterclockwise direction until they stop (Figure 8). While this articleвЂ™s purpose is not to cover the process of modulator replacement I want to take a minute and cover the most important step about putting this system back together. As with any bleeder screw, these are placed at the highest point of the modulator, which on the Delco VI is at the solenoids.Д«leeding of the Delco VI will be required under the following conditions: While this group isnвЂ™t very large, there are enough of them to include in this article. The Delco VI represents the group of modulators equipped with bleeder screw(s).

In addition, the system was used on the вЂњFвЂќ series Camaro and Firebird and many Saturn vehicles. The Delco VI ABS system (See Figure 7) is a four-wheel, three-channel system that was used from 1992 until 1999 on a large number of General Motors FWD vehicles. Once the bleed function has been performed, the system should be bled at the wheels using the appropriate sequence.Д¬ase Study 2 вЂ“ Modulator Replacement on a Delco VI вЂ“ 4-wheel ABS system. Other systems, such as the TEVES VI and some of the import systems, require the use of a dedicated bleed tool to perform a similar process. This function cycles each of the dump valves and then energizes the pump to bleed these hidden areas. For example, the Ford version of the EBC310 requires the вЂњbleed functionвЂќ to be performed through the NGS scan tool (See Figure 6). The majority of ABS modulators not equipped with bleeders will require cycling of the valves and activation of the pump to bleed out these вЂњhiddenвЂќ areas. The fluid paths to the dump valve, pump and low pressure accumulator represent a вЂњdead endвЂќ and will not bleed without additional steps (Figure 5). The fluid flow during wheel-based bleeding is from the master cylinder through the normally open isolation valve and out to the system. Figure 4 shows the fluid path through the left front wheel channel. The red section represents the areas that will not be effectively bled when performing wheel-based bleeding. The green section represents the area that can be bled through wheel based bleeding. In terms of bleeding, the HCU (hydraulic Control Unit) can be divided into two parts, as shown in Figure 3.
