DTC C0245: Wheel Speed Sensor Frequency Error: Diagnosis

  1. Perform DIAGNOSTIC SYSTEM CHECK  under DIAGNOSIS & TESTING. After performing diagnostic system check, go to next step.
  2. If DTC C0035, C0040, C0045 or C0050 is set concurrently with DTC C0245, go to appropriate DTC first for diagnosis. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  table under RETRIEVING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING. If DTC C0035, C0040, C0045 or C0050 is set concurrently with DTC C0245, go to next step.
  3. Check wheel speed sensors and sensor rings for damage. If sensors or rings are damaged, go to next step. If sensors and rings are okay, go to step  5 .
  4. Replace wheel speed sensor or sensor ring. See WHEEL SPEED SENSOR  under REMOVAL & INSTALLATION. After repairs, go to step  12 .
  5. Check for proper routing of wheel speed sensor wiring harnesses. Ensure harnesses are routed away from spark plug wires. If harnesses are properly routed, go to step  7 . If harnesses are not properly routed, go to next step.
  6. Reroute wheel speed sensor wiring harnesses away from spark plug wires. After repairs, go to step  12 .
  7. Install scan tool. Turn ignition on. Set scan tool to snapshot auto trigger mode and monitor wheel speed sensors. Drive vehicle faster than 8 MPH for several minutes. If scan tool triggers on any wheel speed sensor, go to next step. If scan tool does not trigger on any wheel speed sensor, go to step  9 .
  8. Note which wheel speed sensor triggered the scan tool. Diagnose DTC for sensor that triggered scan tool. See DIAGNOSTIC TROUBLE CODE DEFINITIONS  table under RETRIEVING DIAGNOSTIC TROUBLE CODES under DIAGNOSIS & TESTING. After repairs, perform DIAGNOSTIC SYSTEM CHECK  under DIAGNOSIS & TESTING.
  9. Reconnect all previously disconnected components. Using scan tool, clear DTCs. Remove scan tool. Drive vehicle faster than 8 MPH for several minutes. If DTC resets, go to step  11 . If DTC does not reset, go to next step.
  10. Malfunction is intermittent. Inspect all connectors and wiring harnesses for damage resulting in an open or high resistance when connected. After repairs, perform DIAGNOSTIC SYSTEM CHECK  under DIAGNOSIS & TESTING.
  11. Replace EBTCM. See ELECTRONIC BRAKE TRACTION CONTROL MODULE (EBTCM)  under REMOVAL & INSTALLATION. After repairs, perform DIAGNOSTIC SYSTEM CHECK  under DIAGNOSIS & TESTING.
  12. Reconnect all previously disconnected components. Using scan tool, clear DTCs. Remove scan tool. Drive vehicle faster than 8 MPH for several minutes. Perform DIAGNOSTIC SYSTEM CHECK  under DIAGNOSIS & TESTING.
