Wiring diagram practices











Wheel speed sensors and wire colours for each sensor
Right front: Black + White -
Left front: Red + Green -
Left rear: Blue + Pink -
Right rear: Yellow + Brown -

ABS wheel sensors are braded wire to stop interference
Fuses used in ABS circuit
*Main fuse
*ABS fuse 50amps
*Gauge fuse 10amps
*Dome fuse 20amps
*Stop fuse 15amps
*ECU fuse 15amps

Earths used wire colour and pin numbers
10b
7b
white and black

ABS actuator identify which solenoids which wheel cylinder. Wire colours and pin numbers
Right front wheel - pin number 6b 5b, wire colour red,white / red,green

Left front wheel - pin number 1a 2a, wire colour blue,red / blue white

Left rear wheel - pin number 12b 11b, wire colour brown,white / brown, red
Right rear wheel - pin number 14a 15a, wire colour green,black / green, yellow

Under normal braking inlet valve open, outlet valve closed

To reduce wheel brake pressure inlet valve closed, outlet valve open

To hold brake pressure inlet valve closed, outlet valve closed

When ABS is operating to increase wheel brake pressure its constantly changing to maintain maximun brake pressure without blocking up so it does all the 3 conditions above

The ABS motor is working when applying brake pressure
