Service Bleed
WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Do not use any fluid other than clean brake fluid meeting manufacturer's specification. Additionally, do not use brake fluid that has been previously drained. Following these instructions will help prevent system contamination, brake component damage and the risk of serious personal injury.
WARNING:
Carefully read cautionary information on product label. For EMERGENCY MEDICAL INFORMATION seek medical advice. In the USA or Canada on Ford/Motorcraft products call: 1-800-959-3673. For additional information, consult the product Material Safety Data Sheet (MSDS) if available. Failure to follow these instructions may result in serious personal injury.
CAUTION:
Do not allow the brake master cylinder reservoir to run dry during the bleeding operation. Keep the brake master cylinder reservoir filled with clean, specified brake fluid. Never reuse the brake fluid that has been drained from the hydraulic system or damage to the brake system components may occur.
CAUTION:
Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.
CAUTION:
Do not allow the master cylinder brake fluid to overflow from the reservoir. Brake fluid may damage the high-voltage components.
NOTE:
Bleeding the hydraulic control unit (HCU) is required only when removing or installing the HCU, master cylinder or opening the tubes and hoses to the HCU.
NOTE:
The ignition key must be in the ON position when checking the brake fluid level.
- Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with clean, specified brake fluid.
- Connect the pressure bleeder to the brake fluid reservoir.
- Do not apply pressure to the hydraulic brake system at this time.
- Install rubber drain hoses to the brake bleeder screws and submerge the open ends of the hoses in clean, specified brake fluid.
- Connect the scan tool.
- Using the pressure bleeder, apply 2 bars of pressure to the brake system.
- Access the service bleed function on the scan tool.
- While following the instructions on the scan tool, apply the brake pedal one full stroke and then completely release the brake pedal.SERVICE BLEED ERROR CODES
Code Display Action 00 NO ERROR None 01 BFLS (Brake Fluid Level Sensor) LOW Add brake fluid 02 USER BRAKE Do not press the brake pedal 03 HPA (High Pressure Accumulator) LOADED Wait for accumulator to discharge 04 STANDSTILL Block the vehicle from moving 05 VOLTAGE LOW Start the engine or charge the battery 06 FILL PRESSURE LOW Maintain brake bleeder pressure at 2 bars 07 FILL PRESSURE NOT REMOVED Remove the pressure bleeder equipment 08 WRONG BLEEDER Close the open bleeder and open the correct bleeder as instructed 09 BLEEDER NOT OPEN Open the correct bleeder screw 0A BLEEDER OPEN Close all open bleeder screws 0B PEDAL FAST Press brake pedal more slowly 0C PEDAL WEAK Press brake pedal more firmly 0D IGNITION OFF Turn off the ignition 0E FATAL TEST ERROR Verify 12 volt battery voltage. Verify good connection at the pedal travel sensor. If these conditions are OK, carry out another system bleed. - Continue to follow the instructions on the scan tool to complete the service bleed procedure.
CAUTION:
Do not apply pressure to the hydraulic brake system until prompted by the scan tool.
NOTE:
Carrying out the service bleed function drives trapped air from the HCU. Subsequent bleeding removes the air from the brake hydraulic system through the bleeder screws.
NOTE:
Adequate 12-volt battery voltage is required during the system bleed.
NOTE:
The scan tool indicates when the service bleed procedure is not followed correctly. Continue with the service bleed procedure after correcting the condition. Refer to the Service Bleed Error Codes chart below.
