The electronic brake (and traction) control module (EBCM/EBTCM) controls a bi-directional magnetic rotary solenoid. The solenoid is located in the steering gear. The solenoid adjusts the amount of power steering assist in order to achieve a given level of driver effort in order to turn the vehicle. The EBCM/EBTCM varies the steering assist by adjusting the current flow through the solenoid. The amount of steering assist adjusted for steering is dependent upon vehicle speed. As the vehicle speed increases, the following actions occur:
| • | The steering assist decreases. |
| • | The driver effort increases. |
As the vehicle speed decreases, the following actions occur:
| • | The steering assist increases. |
| • | The driver effort decreases. |
If any open or short is present in CKT 345 (WHT) or CKT 1787 (GRY) the EBTCM will set DTC C1241 Magnasteer Malfunction. If DTC C1241 is current, the scan tool will not control variable effort steering.
