Chart C-1-1 FL Sensor Output Inspection Procedure

Step
1 1. Turn the key off.
2. Disconnect coil integrated module connector.
3. Jack up the vehicle with all four wheels off the ground.
Measure the AC voltage between coil integrated module
connector terminals while turning FL wheel at a speed of 1
RPS:
Is the check between coil integrated module connector (C-4)
terminals 2 and 10 than under 200 mV?
2 1. Disconnect the wheel speed sensor.
2. Measure resistance between the wheel speed sensor
connector terminals 1 and 2.
Is the check between connector (C-13) terminals 1 and 2 within
2.0k - 2.8k ohms?
3 Reconnect all components, ensure all components are properly
