  1. 2. If DTC C0245 is a history code, this step checks if a specific Wheel Speed Circuit Malfunction DTC is set concurrently with DTC C0245.
  2. 7. This step checks if the wheel speed sensor harness is routed in close proximity to the spark plug wires.
  3. 9. In this step, if the scan tool can record any erroneous wheel speed sensor signals, diagnose that sensor(s) first.
