ABS: 4E-54
2 1) Check for continuity between “2” (B/Y) and “3” (W/R) at
the coupler.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
Tester knob indication
Continuity ( )
ABS control unit coupler (Harness end)
Is there continuity between “2” and “3”?
• Inspect the wire
harness. (Faulty
sensor wire)
• Faulty front wheel
speed sensor
Go to Step 3.
3 1) Turn the ignition switch ON with the ABS control unit
coupler disconnected, measure the voltage between “3”
(W/R) and “24” (B/W) at the coupler.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
Tester knob indication
Voltage ( )
Normal value (“3” – “24”)
0 V
ABS control unit coupler (Harness end)
Is the voltage between “3” and “24” normal value?
Replace the ABS
control unit/HU.
Inspect the wire
