Diagnostic Fault Information

Circuit/System Description

The electronic brake control module (EBCM) applies a 5 V reference and provides a low reference to the steering wheel angle sensor. The EBCM

monitors the signal circuit and the three phase circuits to determine the steering wheel position. The EBCM receives three signal inputs from the

steering angle sensor. The Phase C Index Pulse signal is only High when the steering wheel is centered or within a few degrees of the straight ahead

position. The 2 input signals Phase A and Phase B are approximately 90 degrees out of phase. Once calibrated, the EBCM dynamically interprets

the relationship between the Phase A and Phase B inputs, and determines the position of the steering wheel and the direction of the steering wheel

rotation.

Conditions for Running the DTC

* The ignition is ON.

* Ignition voltage is greater than 9 V.

Conditions for Setting the DTC

* Opens, short to ground, or short to voltage.

* The calculated steering angle from the steering angle sensor does not correlate with the steering angle calculated from the yaw rate.
