ABS ( ANTI - LOCK BRAKE SYSTEM FOR FORD RHD)

Wiring Diagram Practice 

Using the wiring diagram in the workshop manuals identify the wheel speed sensors and list their wire colors for each sensor

B = BLACK                                  L = BLUE                                    R = RED

BR =BROWN                               LG = LIGHT GREEN               V = VIOLET

G = GREEN                                  O = ORANGE                            W = WHITE

GR = GRAY                                  P = PINK                                     Y = YELLOW

Front right + Black - White

Front left   + Red   -  Green

Rear left    + Blue -   Pink

Rear right  + Yellow _ Brown

On the ABS sensor what is the reason for the braded wire?

The reason for the braded wire or shielding for protection from radio interference or back EMF.

Identify and lest the fuses that are used by ABS circuit

F14, 4 IF1, 17 3A , 19 

Identify the earth for the ABS control unit and ABS motor their wire colors what pins numbers

ABS control unit W-B (L/B) and pin number is 7B , and 10B

ABS motor earth color is W - B , and 1A

On the wring diagram for the ABS actuator , identify which solenoids control which wheel cylinder.

Then note the wire colors and pin numbers.

Front Right wheel            Pin number 5B

                                          Wire color  L _ R

Front Left Wheel              Wire color  L - R

                                           Pin number  1A

Rear Left Wheel              Pin number  12B

                                          Wire color   BR - W

Rear Right Wheel           pin number  15A

                                         Wire color   G - Y

Using the next picture as guide, which of the foll wing gives the correct condition of the inlet and outlet solenoids valves under normal braking?

A: wrong Inlet vole open            outlet valve Open

B: correct Inlet valve open         outlet closed 

C: wrong  Inlet valve closed        outlet valve closed

D: wrong Inlet valve closed         outlet valve closed

Using the picture, which of the following gives the correct condition of the inlet and outlet solenoid valves when the ABS is operating to reduce wheel brake pressure?

A: wrong  Inlet valve en             outlet valve open

B: wrong  Inlet valve open         outlet valve closed

C: correct Inlet valve closed      outlet valve open

D: wrong  Inlet valve closed       outlet valve closed

Using the picture, which of the following gives the correct condition of the inlet and outlet solenoids valves when the ABS is operating to hold brake pressure?

A: wrong Inlet valve open          outlet valve open 

B: wrong Inlet valve open        outlet valve close

C: wrong Inlet valve closed     outlet valve open

D: correct Inlet valve closed      outlet valve closed

Using the picture which of the following gives the correct condition of the inlet and outlet solenoid valves when the ABS is operating to increase wheel brake pressure?

A: wrong Inlet valve open         outlet valve open 

B: correct Inlet valve open        outlet valve closed

C: wrong Inlet valve closed       outlet valve open 

D: wrong Inlet valve closed       outlet valve closed

In the four cases above state when the ABS motor will be working?

The ABS will be working in these four cases gets hold pressure, reduce pressure, increase pressure,,in the brake system.
