Operation
The supply to brake light switch 29 is taken from fuse 31, across the white 29-pole connector 152A. When the brakes are applied, the contacts will close and brake lamps 30 will be energized.
Depending on the market, one or two lamps (30) are used on each side for the brake lights. If two lamps are used, the second lamp is connected by means of cable 132A (3-D and 5-D) or cable 132B with connector 269 (2-D and 4-D).
European market
Cable 132A (3-D and 5-D) is not used and connector 269 (2-D and 4-D) is not fitted. Only one lamp on each side will light up when the brakes are applied. The extra lamps are used for the rear fog lights instead.)
Cars for the SE, FI and GB markets are fitted with high-level brake light at the bottom of the rear window. On 3-D and 5-D cars, the brake light is connected across two single-pole connectors (one in the luggage compartment at the left-hand air outlet and one in the tailgate), whereas on the 2-D and 4-D models, it is connected across two-pole connector 59.
Australian, Middle East and Far East markets
Cable 132A (3-D and 5-D) is used. Connector 269 (2-D and 4-D) is fitted, and two lamps will therefore light up on each side of the car.
In addition, cars for these markets are equipped with high-level brake light 109 at the bottom of the rear window. On 3-D and 5-D cars, the brake light is connected to the left-hand light cluster in the tailgate by means of two single-pole connectors, whereas on the 2-D and 4-D models, it is connected across two-pole connector 59.
USA, Canadian and Japanese markets
On cars for these markets, cable 132A (3-D) and cable 138B (2-D and 4-D) is used, and two lamps thus light up on each side of the car.
In addition, cars for these markets are equipped with high-level brake light 109 at the bottom of the rear window. On 3-D cars, the brake light is connected to the left-hand light cluster in the tailgate by means of two single-pole connectors, whereas on the 2-D and 4-D models, it is connected across two-pole connector 59.
Convertible
On the Convertible, high-level brake light 109 is located in the spoiler and is connected by means of two 2-pole connectors 59. The connectors are located at the left-hand hinge of the boot lid.
Fault-tracing hints
1. Check fuse 31 and check that the supply to it is live.
2. Check that the supply to brake light switch 29 is live.
3. Operate the brake light switch. Check the bulbs and check that the supplies to them are live. Check the earthing at each lamp.
4. Check the connectors, cable harnesses and earth connections.
