ABS: 4E-57
1 5) Measure the resistance between “2” (B/Y) and ground at
the ABS control unit coupler.
Special tool
(A): 09900–25008 (Multi circuit tester set)
(B): 09900–25009 (Needle-point probe set)
Tester knob indication
Resistance (Ω)
Normal value (“2” – Ground)
∞ Ω (Infinity)
Is the resistance between (2) and ground OK?
Go to Step 3. Go to Step 2.
2 1) Disconnect the rear wheel speed sensor coupler.
2) Measure the resistance between “A” (W) and ground at
the rear wheel speed sensor coupler.
Special tool
(A): 09900–25008 (Multi circuit tester set)
Tester knob indication
Resistance (Ω)
Normal value (“A” – Ground)
∞ Ω (Infinity)
Is the resistance between “A” and ground OK?
Inspect the wire
harness. (Faulty B/Y
wire)
Replace the rear wheel
speed sensor.
