Circuit Description
EBD warning lamp (brake warning lamp) is controlled by parking brake switch, brake fluid level switch and ABS
hydraulic unit / control module assembly through lamp driver module in combination meter.
EBD warning lamp turns ON when parking brake switch is ON and/or brake fluid level is lower than minimum level.
The information of parking brake switch and brake fluid level are transmitted from BCM to lamp driver module in
combination meter through CAN communication line.
Troubleshooting
Step

• Parking brake is completely released.
• Brake fluid level is upper than the minimum level.
Are the check results OK?
2 1) Turn ignition switch to ON position.
Does "ABS" warning lamp come on steady?
3 1) CAN communication circuit between combination meter,
ABS hydraulic unit / control module and BCM referring to
"DTC U1073: Control Module Communication Bus Off: ".
Is CAN communication circuit in good condition?
