ABS, EPS, and BAS problems with my Mercedes E-Class

I have a 2000 Mercedes E-Class with a diesel engine and 450,000 km on the odometer. My brake lights are not working and when I brake, the ABS, EPS, and BAS lights come on. I've already replaced the brake light switch, but the problem persists. Does anyone have an idea what the cause might be or how I can solve this?

Check the fuses related to the brake lights and ABS system to ensure they are not blown. If the fuses are fine, inspect the wiring and connectors for any signs of damage or corrosion. Let me know how it goes or if you have further questions.

It's all fine now, they say it could be in the light module. I've been working on it for 14 days.

Inspect the light control module for any signs of damage or malfunction. Sometimes, a faulty module can cause issues with the brake lights and related warning lights. If you're not comfortable checking this yourself, it might be best to have a professional mechanic take a look. Let me know if you need further assistance or have any questions.

Where is the module? I don't know.

The light control module in your Mercedes E-Class is typically located in the trunk, near the battery or fuse box. Check for any signs of damage or loose connections. If you're unsure, consulting a repair manual specific to your model can be helpful. Let me know if you need more guidance or have further questions.

Where can I find that manual?
