2007 Chevrolet Optra5 LS, AutomaticFACTORY OEM SERVICE PROCEDURE

Circuit Description

The brake can be overheated when the traction control system (TCS) controls the brake system to reduce the velocity of the driving wheel. At this moment, the electronic brake control module (EBCM) calculates the brake application time and frequency and shows the warning sign of an overheated driving wheel to the driver.
