I'm getting the message to "Check Rear Lights" and its the lower stop lights (in the guards) not working. The High Mounted Stop Light works fine so I assume it cant be a faulty Stop Light Switch The globes and the relay are ok, does anyone have any clues. Could it be the Security and Locking Control Module located under the fuse box? I notice the wiring for the lower stop lights goes through this module on there way to the globe.
