Lamp Brake Warning Output Circuit Failure

Check these first

• A failed red brake warning lamp
• An open or short in the red brake warning lamp circuit
• A poor electrical connection at the warning lamp or cluster
• A failed anti-lock brake system module

What to do next

1. Command the red brake warning lamp with a scan tool
2. Inspect the warning lamp and cluster connectors
3. Test the warning lamp output circuit for open and short faults
4. Check the instrument panel cluster for faults
5. Replace the warning lamp or cluster if the circuit tests good
6. Clear the code and retest
