DTC C0710: Steering Position Signal Malfunction

  1. Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK  . After performing diagnostic system check, go to next step.
  2. Install scan tool. Turn ignition switch on. Using scan tool, observe Steering Position Pulse Width Modulation (PWM) parameter in Suspension Control Module. If scan tool indicates data parameter is within 0-10 ms, go to next step. If scan tool indicates data parameter is not within 0-10 ms, go to step  4 .
  3. Activate steering position PWM input. Using scan tool, observe steering position PWM data parameter while turning the steering wheel. If steering position PWM data parameter changes state while turning steering wheel, check for intermittent and poor connections in wiring system. See NOTES ON INTERMITTENTS  under DIAGNOSIS & TESTING. If steering position PWM data parameter does not change state while turning steering wheel, go to next step.
  4. Turn ignition switch off. Disconnect EBCM harness connector. Turn ignition switch on. Using scan tool, observe steering position PWM data parameter. If scan tool indicates PWM data parameter is within 0-10 ms, go to step  7 . If scan tool indicates data parameter is not within 0-10 ms, go to next step.
  5. Check ECBM signal circuit for a short to ground. If a short to ground was found and repaired, go to step  10 . If a short to ground was not found, go to next step.
  6. Check suspension control module harness connector for a poor connection. If a poor connection was found and repaired, go to step  10 . If a poor connection was not found, go to step  8 .
  7. Check ECBM harness connector for a poor connection. If a poor connection was found and repaired, go to step  10 . If a poor connection was not found, go to step  9 .
  8. Replace suspension control module. See ESC/CVRSS CONTROL MODULE  under REMOVAL & INSTALLATION. Calibrate NEW control module. See CALIBRATING ESC/CVRSS CONTROL MODULE  under ADJUSTMENTS. If replacement is complete, go to next step.
  9. Replace EBCM. See appropriate ANTI-LOCK article. If replacement is complete, go to next step.
  10. Using scan tool, clear DTCs. Operate vehicle under normal driving conditions. If DTC resets, go to step  2 . If DTC does not reset, system is okay.
