Most likely there is an open circuit after the monitor. Is there is voltage on pin 5 (output to light, white wire) of the monitor when the brakes are applied?
There is one connector between the high level brake light and the filament monitor, H8-4. You may want to check this for power when the brakes are applied (Pin 6, white wire)and pins 4 and 7 for ground. This connector is located "behind the left rear wheel housing". From the diagram it looks like it is near the main lighting harness as it goes over the wheel arch.
The monitor should have power on pins 9 and 10 when the brake is applied. There should be low resistance across the monitor sensor pins 10 and 5. Hope this helps.
