TROUBLE DIAGNOSES — Diagnostic Procedure 2 — ABS Solenoid
BR-61flowchartInlet (HOLD) coil is roughly 2× the resistance of the outlet (DUMP) coil: ~5.4-6.0 Ω vs ~2.7-3.0 Ω. C/U-side pins and actuator-side pins are different — the harness flips some pairs, so it is important to use the correct table per side.
Diagnostic Procedure 2
ABS SOLENOID
1
A — CHECK ABS SOLENOID RESISTANCE. Check resistance between control unit connector (vehicle side) and body ground. Flashing number 5 (Fr. R.H.): Terminal ① 5.4-6.0 Ω; Terminal ⑨ 2.7-3.0 Ω. Flashing number 6 (Fr. L.H.): Terminal ② 5.4-6.0 Ω; Terminal ⑩ 2.7-3.0 Ω. Flashing number 7 (Rr. R.H.): Terminal ⑤ 5.4-6.0 Ω; Terminal ⑬ 2.7-3.0 Ω. Flashing number 8 (Rr. L.H.): Terminal ⑥ 5.4-6.0 Ω; Terminal ⑭ 2.7-3.0 Ω.
O.K.
Replace ABS Control Unit.

B — Remove actuator connector and check resistance actuator side terminal and body ground. Flashing number 5 (Fr. R.H.): Terminal ② 5.4-6.0 Ω; Terminal ⑥ 2.7-3.0 Ω. Flashing number 6 (Fr. L.H.): Terminal ① 5.4-6.0 Ω; Terminal ⑤ 2.7-3.0 Ω. Flashing number 7 (Rr. R.H.): Terminal ④ 5.4-6.0 Ω; Terminal ⑧ 2.7-3.0 Ω. Flashing number 8 (Rr. L.H.): Terminal ③ 5.4-6.0 Ω; Terminal ⑦ 2.7-3.0 Ω.
O.K.
Repair harness between Control Unit and actuator.

3
Perform individual actuator relay check. Refer to "Individual Component Check".
N.G.
Replace actuator relay.
O.K.
4
Replace actuator.
