Good

Carefully re-do this troubleshooting guide steps.
If no problems were found with the circuits or connectors and DTC still occurs, replace the EPB switch and go to "VERIFICATION OF REPAIR " procedure.

No Good

Repair open or short in circuit and then go to "VERIFICATION OF REPAIR " procedure.
