2022-2023 BMW High Beam Headlight Failure Message

Owners of various 2022-2023 BMW models, including the 2022 BMW X5 manufacturer_communication, may encounter a specific warning message related to their vehicle's exterior lighting system. This technical service bulletin (TSB), identified by NHTSA ID 10239611, addresses instances where the vehicle's check control system detects an issue with the high beam headlights.

Symptoms

The primary symptom owners will notice is a "Headlight check control (CC) message 128" displayed on the instrument cluster. This message explicitly states: "High beam headlight failure". This warning indicates that the vehicle's system has detected a malfunction preventing the high beam headlights from operating correctly.

Fault Codes / DTCs

When diagnosing this issue, technicians are likely to find specific fault codes stored in the vehicle's memory during a vehicle test. These diagnostic trouble codes (DTCs) point to a short circuit condition within the headlight system:

• 80419A: Left high-beam headlight: Short circuit
• 8041A5: light outputs: Number of permitted short circuit cycles exceeded

These codes confirm that the system has registered an electrical short, potentially due to repeated occurrences, leading to the displayed warning message.

Diagnosis / Trigger Conditions

The presence of fault codes 80419A and 8041A5 strongly suggests an electrical short circuit within the high beam headlight system. The "light outputs: Number of permitted short circuit cycles exceeded" code, in particular, indicates that the vehicle's control unit has detected multiple short circuit events, leading it to flag the issue and display the warning. A thorough electrical system diagnosis is required to pinpoint the exact location and cause of the short circuit.

Repair Procedure Summary

While this manufacturer communication (NHTSA ID 10239611) highlights the problem and associated fault codes, it implies a diagnostic and repair process focused on the electrical system. The repair will involve identifying and rectifying the short circuit within the high beam headlight wiring or components. This may include inspecting wiring harnesses, connectors, and the headlight assembly itself for damage or faulty connections that could cause a short. After the repair, the fault codes should be cleared, and the system re-tested to ensure proper function and that the "High beam headlight failure" message no longer appears.

Owner Action

If your 2022-2023 BMW, including the 2022 BMW X5 manufacturer_communication, displays the "High beam headlight failure" message or you suspect an issue with your high beams, it is recommended to contact your authorized BMW dealership. They have the specialized diagnostic tools and technical information, including this manufacturer communication, to accurately diagnose the fault codes 80419A or 8041A5 and perform the necessary repairs to resolve the short circuit condition.
