If your brake lights won't work niether will your traction control. Vehicle Application: 2003 Cadillac CTS 3.2L Customer Concern: Left and right brake lights inoperative. Shift interlock intermittently inoperative as well. Tests/Procedures: 1. Check battery voltage at stop lamp switch Red/White wire terminal "A". If no voltage, check STOP LP SW fuse. 2. Check for battery voltage at stop lamp switch White wire terminal "B" with brake pedal applied. If no voltage, replace stop lamp switch. 3. Check circuit 17 (White wire) integrity from stop lamp switch to stop lamp bulbs. This circuit goes through two splice packs, SP200 and SP302. 4. Check stop lamp bulb ground circuits for opens/high resistance. 5. If circuits are OK, check for faulty stop lamp bulbs or sockets. Potential Causes: Bulbs Sockets Stoplamp Switch Wiring Tech Tips: SP200 is under the instrument panel, above the steering column. SP203 is in the passenger compartment, on the frame rail, left of the driver's seat.

My car did this recently. My brake lights (passenger and drivers side as well as 3rd light) were light up constantly and burned out. Replaced bulb- still on constantly. The EBCM went bad and the brake panel lights on dash were illuminated. Replaced EBCM at dealership.

The front and rear light bulbs are prone to premature failure. Our technicians tell us that the front bulbs can be very difficult to replace.
After the car is stopped, the brake lights stay on. On after tapping the brakes do the lights go off.
