Lights off: Brake lights both go, but the BC indicates when stepping on the pedal, taillight is defective. For this purpose, when braking at the front left, the standlight is applied...
Light on: it indicates brake light and tail light defective. On the right also the brake light or both threads in the 2 thread lamp on...The magnetic lock on the gearbox also opens the selector lever when the ignition is locked, but only when the light is on.
Who's got an idea? The lamp carrier on the back right I had once plugged off, if there is a short circuit, just no success. And how is brake connected to the right with the front of the standlight. I find it curious, but it's just a car with its own life.
