DTC C0245: Wheel Speed Deviation

  1. Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK  under DIAGNOSIS & TESTING. After performing diagnostic system check, go to next step.
  2. If DTC(s) C0036, C0041, C0046, C0051 or C0056 set concurrently with a history DTC C0245, repair cause to concurrent DTC(s) before repairing cause of DTC C0245. If no DTC(s) are set concurrently with a history DTC C0245, go to next step.
  3. Inspect suspect wheel speed sensor for physical damage. If physical damage is evident, go to next step. If damage is not evident, go to step  5.
  4. Replace damaged wheel speed sensor. See WHEEL SPEED SENSOR  under REMOVAL & INSTALLATION. Go to step  14.
  5. Inspect jumper harness for physical damage. If physical damage is evident, go to next step. If damage is not evident, go to step  7.
  6. Replace wheel speed sensor jumper harness. See WHEEL SPEED SENSOR  under REMOVAL & INSTALLATION. Go to step  14.
  7. Check for proper routing of wheel speed sensor harness. Ensure wheel speed sensor harness is routed away from spark plug wires. If harness is not properly routed, go to step  8. If harness is okay, go to step  9.
  8. Reroute wheel speed sensor harness away from spark plug wires, then go to step  14.
  9. Install scan tool. Turn ignition switch to RUN position. Set scan tool to Snap Shot Auto Trigger mode. Monitor wheel speed sensors. Carefully drive vehicle greater than 8 MPH for several minutes. If scan tool triggered any wheel speed sensor, go to next step. If scan tool did not trigger any wheel speed sensor, go to step  11.
  10. Note which wheel speed sensor triggered scan tool. See appropriate test for DTC set. Go to step  14.
  11. Reconnect all previously disconnected components. Using scan tool, clear DTCs. Remove scan tool from DLC. Carefully drive vehicle greater than 8 MPH for several minutes. Check for DTC. If DTC resets as a current DTC, go to step  13. If DTC does not reset as a current DTC, go to next step.
  12. Malfunction is intermittent. Inspect all connectors and harnesses for damage that may result in an open or high resistance when connected. See INTERMITTENT & POOR CONNECTIONS  under DIAGNOSIS & TESTING. Go to step  14.
  13. Replace EBCM. See ELECTRONIC BRAKE CONTROL MODULE & BRAKE PRESSURE MODULATOR VALVE ASSEMBLY  under REMOVAL & INSTALLATION. Go to next step.
  14. Using scan tool, clear DTCs. Operate vehicle to verify repair. If DTC resets, go to step  2. If DTC does not reset, system is okay.
