Circuit Description
EBD warning light (brake warning light) is controlled by ESP® control module and BCM through light driver module in
combination meter.
If EBD system is in good condition, ESP® control module turns EBD warning light ON at the ignition switch ON, keeps
it ON for 2 seconds and then turns it OFF.
EBD warning light is turned ON continuously at the following conditions.
• EBD system is an abnormality
• Connector of ESP® control module is disconnected
• Parking brake switch is ON
• Brake fluid level is lower than minimum level
The information of parking brake switch and brake fluid level are transmitted from BCM to light driver module in
combination meter through CAN communication line.
