4E-59 ABS:
6 1) Check the continuity between “18” (W/Y) on the ABS
control unit coupler and “D” (W/Y) on the rear wheel
speed sensor coupler.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
(B): 09900–25009 (Needle pointed probe set)
Tester knob indication
Continuity test ( )
Normal value (“18” – “D”)
Continuity ( )
Is the resistance between “18” and “D”?
Go to Step 7. Inspect the wire
harness. (Faulty W/Y
wire)
7 1) Connect the rear wheel speed sensor coupler.
2) Connect three 1.5 V dry cells “a” in series as shown and
make sure that their total voltage is more than 4.5 V.
Measure the current between (+) dry cell terminal and
“2” (B/Y) on the ABS control unit coupler.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
(B): 09900–25009 (Needle pointed probe set)
Tester knob indication
Current ( , 20 mA)
Normal value
3 – 14 mA
Is the current OK?
Replace the ABS
control unit/HU.
Replace the rear wheel
speed sensor.
