Good
- Check for wheel speed sensor related failure in HECU system, and then perform applicable troubleshooting.
- Once wheel speed sensor related failure is fixed, re-do troubleshooting guide steps carefully.
- If no problems were found with the circuits or connectors, replace the PCM and then go to "VERIFICATION OF REPAIR " procedure.
No Good
- Repair or replace as necessary and then, go to "VERIFICATION OF REPAIR " procedure.
