Brake Systems
This is first the 
ECB, or Electronically Controlled Brake Systems symbol, also known as Electronic Brake Force Distribution. Note that the only difference between this and the Canadian brake warning symbol – the exclamation point in a circle – is the color. Yellow/amber indicates a less serious problem than the red version. The electronic control represents a functional enhancement and may be inoperable, including a brake booster issue, but the brakes themselves will still operate.
- But first, is one of these truly your symbol?? If yes, continue on below.
- Otherwise return to our main Picture Symbols page and scan again!
Second, and before continuing, note that if you have a hybrid vehicle, at least one manufacturer uses the symbol above to indicate a problem with the Regenerative Brake System. Click the link for more.
However, as electronic control of overall brake systems expands, the symbol above is used in Canada to alert to a problem any part of the brake system controlled electronically. These can include Automatic Brake Hold or Electronic Parking Brake system issues, as well as those described above.
In the U.S., the text symbol to the left, Brake System, is used in yellow/amber. Again as above, the brakes themselves, as operated by the brake pedal, remains a hydraulic system and will continue to function normally.
However, if the red BRAKE text warning symbol is also lit, contact your dealer or authorized service center immediately.
Note that the symbol of a circle with “brackets” on either side, broken or otherwise, represents brake components. What is shown inside and the details of the “brackets” and color specify the nature of the problem.

These symbols are Parking Brake Indicator 
If any of these symbols are flashing, it indicate that service is necessary. Also, the first image to the right with the wrench or spanner added is used with Electronic Parking Brakes and indicates that it needs to be serviced. The car can be driven, but be sure to have it serviced as soon as possible in order to maintain the parking brake’s availability.
The letter P is shown above for “Park”. It is inside the circle in brackets, which is always used to represent brakes. The symbol holding the whole word is also a park brake indicator, but may indicate an electric park brake fault. 
Note that the symbol to the right is associated, and may be serious.
