Is there continuity between
F
and

?
Step 2
1) Measure the resistance between
F
terminal and ground at
the ABS control unit coupler.

Is the resistance between
F
and ground OK?
Step 3
1) Disconnect the front wheel speed sensor coupler.
2) Measure the resistance between
2
terminal and ground at
the front wheel speed sensor coupler.

POSSIBLE CAUSE
Wheel speed sensor circuit open or short, loosen contact in
wheel speed sensor connector, input amplifier in ABS control
unit failure, etc.
