TROUBLE DIAGNOSIS FOR SYSTEM BRC-57 [VDC/TCS/ABS] C D E G H I J K L M A B BRC VDC ACTUATOR Turn ignition switch OFF and Disconnect VDC actuator connectors. Check continuity and resistance value CAUTION: Make sure actuator motor is correctly grounded. Actuator Operation Inspection ● Turn ignition switch OFF, apply a voltage of 12 V between VDC CAUTION: ● Above check should be performed after motor relay unit ● To prevent overheating, do not drive actuator motor more ● Motor reverse voltage occurrence time is standard when ° C (68 ° F), and this time is a little shorter when battery voltage is low or the air temperature is low.
