BRAKE LIGHT CIRCUIT ERROR means that the car thinks it has too much current
in the brake light circuit. This comes from a switch that is mounted on the
brake pedal. There are two switches mounted on the brake pedal, and I am not
sure which one causes the error.
If the message is LEFT BRAKE LIGHT OUT (or equivelent) then the left brake
light is not working. If the right brake light is not working, then the
message will be clear. If the brake light is really working, then the ground
for the light(s) on the particular corner may not be connected well. Unplug
the light assembly and check the condition of the pins. You would do well to
completely remove the lamp housings, 4 screws, and inspect the intergrity of
The BRAKE LIGHT CIRCUIT ERROR message remains on until the car is switched
off, then the message may or may not return when the brake pedal is pressed.
My car can give the message, and I can switch the car off then back on
again, and the message goes away and does not return for several days, or
weeks. I have been struggling with this for going on three years now, and
the measage is very intermittant.
