325 ABS

Circuit Description
As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses the frequency of the AC signal to calculate the wheel speed.

Conditions for Running the DTC
^ Ignition switch is in the RUN position.
^ The rear speed sensor signal is greater than 13 km/h (8 mph).

Conditions for Setting the DTC
The corresponding front wheel speed sensor input is less than 6 km/h (4 mph) for 5 seconds (120 seconds in order to set multiple missing sensor DTCs.

Action Taken When the DTC Sets
^ The ABS indicator lamp turns on.
^ The ABS disables for as long as the malfunction is present.
^ If DTC C0222 and DTC C0226 are both set or if DTC C0236is set with either of these DTCs, the BRAKE indicator is also commanded ON and the DRP is disabled for as long as both malfunctions are present.

Conditions for Clearing the DTC
^ Repair the condition(s) responsible for setting the Diagnostic Trouble Code (DTC).
^ Use a scan tool in order to clear the DTC.
^ After the DTC is cleared and the ignition is ON, the ABS indicator will remain on until the EBCM completes a power-up self test. This test concludes when the vehicle reaches a speed of greater than 13 km/h (8 mph) and the wheel speeds are verified by the EBCM.
