POSSIBLE CODE(S)
C11 - 45 -- Electrically shorted or open front right speed sensor circuit or coil.

DESCRIPTION
Code C1145 is generated by the anti-lock electronic control module's detection of an open or shorted wheel speed sensor coil or an open or shorted condition in Circuits 514 (Y/T) or 516 (Y/BK) between the wheel speed sensor and the anti-lock brake control module. If this fault is detected during the anti-lock electronic control module's self-check after key ON, the ABS warning lamp will come on immediately. This is generally an indication of a constant wiring or component fault. If the ABS warning lamp proves out normally and comes on later when the vehicle is driven, this is generally an indication of an intermittent wiring or component fault.

POSSIBLE CONTRIBUTING COMPONENT/VEHICLE WIRING CONCERNS

- Terminal damage or backout in two-pin sensor connector
- Open or shorted front right speed sensor coil
- Open or shorted Circuit 514 (Y/R) or 516 (Y/BK)
- Improper front right wheel speed sensor cable routing leading to above
- Defective front right wheel speed sensor electrical test circuit in anti-lock brake control module
