TROUBLE DIAGNOSES — Diagnostic Procedure 1 (Wheel sensor and harness)
BR-60flowchartC/U-side sensor pin mapping differs from the ADD supplement's E96 actuator connector (BR-7034). Here the resistance check is at the ABS control unit connector, on the harness side of the rolling stock — so the sensor + harness loop is in series. Sensor coil resistance window 0.8-1.2 kΩ matches Preliminary Check 3 (BR-50).
Diagnostic Procedure 1
1
INSPECTION START — Remove battery negative terminal connector.
2
A — CHECK WHEEL SENSOR RESISTANCE. Check resistance between control unit connector (vehicle side) terminals: Flashing number 1 (Fr. R.H.) ㉙ and ㉛; Flashing number 2 (Fr. L.H.) ㉚ and ㊳; Flashing number 3 (Rr. R.H.) ㊴ and ㊶; Flashing number 4 (Rr. L.H.) ㊵ and ㊽. Resistance: 0.8 - 1.2 kΩ.
