When the parking brake is applied, the switch at the parking brake lever forms a connection with «weight». Thus, the indicator should light up, which, when the ignition is on, is supplied with current (voltage). When the brake is released, the indicator goes out again.
The lamp does not light up when the handbrake is applied: check the fuse (chapter «Body electrical system»).
Remove and check bulb (see beginning of chapter).
If this fails, release the rear switch at the parking brake lever after removing the rear center console (see chapter «Salon»), disconnect the wire from the switch (behind the lever) and bring the plug to bare metal.
If the lamp now lights up, then the switch is faulty.
The lamp does not go out when the parking brake is released: disconnect the wire from the parking brake switch as described above, but leave the plug hanging in the air.
If the lamp goes out, then the switch is defective or not installed correctly.
If it continues to burn, then the cable is frayed somewhere, and there is a short circuit to «mass».
