Diagnostic Procedure 8 — wheel speed sensor resistance
1
INSPECTION START — Remove battery negative terminal connector.
2
[A] CHECK SPEED SENSOR RESISTANCE. Disconnect control unit connector. Check resistance between control unit connector (vehicle side) terminals. Flashing number 5: terminals ④ and ⑥. Flashing number 6: terminals ⑪ and ㉑. Flashing number 7 or 8: terminals ⑦ and ⑨. Resistance: 0.8 - 1.2 kΩ.
O.K.
Replace control unit.
N.G.
3
Refer to Preliminary Check 3 result. Check whether sensor has 0.8 - 1.2 kΩ resistance.
N.G.
Replace sensor.
O.K.
4
Repair harness between sensor connector and control unit connector.
