Pinpoint Test F: DTC C1222 - Speed Wheel Mismatch/ DTC C1296 (LF), DTC C1297 (RF), DTC C1298 (RR), DTC C1299 - Wheel Speed Signal Fault

Normal Operation
The wheel speed sensor and sensor ring generates a square wave signal to the anti-lock brake system (ABS) module that is proportional to the wheel speed. The ABS module compares the wheel speed inputs from all the wheel speed sensors to determine an impending wheel lockup. Incorrect tire size can set these DTCs as well.

Possible Causes
^ ABS module
^ Wheel speed sensor ring
^ Wheel speed sensor
