04-18 DIAGNOSTICS - ANTI-LOCK BRAKING SYSTEM (ABS)

(b) Disconnect the socket connector B003 of right
rear wheel speed sensor and the socket
connector B002 of left rear wheel speed
sensor.

04

(c) Measure the resistance value between the
pins of right and left rear wheel speed
sensors.
Standard electrical resistance (check
B002/B003
whether there existent an open circuit)

Connection of the Standard value
multimeter
ftwxd041433
B003（1）-B003（2）
0.9 - 1.8 KΩ
B002（1）-B002（2）

(d) Measure the voltage between the pin of the
connector of wheel speed sensor and ground.
Standard resistance (check whether there
B002/B003 is short circuit)

Connection of the Standard value
multimeter

B003（1） - ground
ftwxd041434
B003（2） - ground
≥ 1 MΩ
B002（1）- ground

B002（2）- ground

Check whether the result is normal?

Yes> go to step 3
NO > Replace or change the wheel speed sensor.

3 . Check the rear wheel speed sensor output signal
