There are pressure switches (two I believe) attached at the master cylinder. They sometimes go bad. If you disconnect the wires from them and check with an ohmmeter, you should see a big change in resistance ( infinite to nearly zero) when you press on the brake pedal. I believe that the electronic logic, where ever it may be, turns on the warning light if it senses pressure in the front brake circuit and not the rear or vise-versa. Larry A. |
