2024-2025 BMW Taillamp Check Control Message TSB

Symptoms

Owners of affected 2024-2025 BMW vehicles may intermittently observe a "CHECK CONTROL MESSAGE (CCM) PRESENT FOR THE TAILLAMPS" warning message. This message indicates a potential issue with various taillamp functions, including the brake lights, taillights, side lights, turn indicator, and daytime driving lights.

Fault Codes / DTCs

When the BMW taillamp check control message appears, diagnostic scans may reveal one or more of the following fault codes, all indicating a communication issue with the LED driver:

• 80801E: LED driver: Communication faulty
• 80819E: LED driver: Communication faulty
• 80831E: LED driver: Communication faulty
• 80849E: LED driver: Communication faulty

Cause

The root cause of the "CHECK CONTROL MESSAGE (CCM) PRESENT FOR THE TAILLAMPS" and associated fault codes is a software error. This error specifically affects the RLMAL, RLMAR, RLML, and RLMIR control units, which manage the inner and outer taillamps.

Repair Procedure Summary

BMW Service Information Bulletin SIB 63 07 25 outlines a software update as the corrective action for this issue. The repair involves updating the software of the RLMAL, RLMAR, RLML, and RLMIR control units.

1. Determine Current I-level: A technician will first check the vehicle's current I-level (integration level) using either the AIR or Key Reader/AWP (Aftersales Workplace) applications.
2. Software Programming: If the vehicle's I-level is lower than ...26-03-532, the vehicle will be programmed to I-level ...26-03-532 or higher using ISTA 4.58.2x software, released on March 03, 2026, or newer.
3. Programming Steps: The programming process requires connecting a BMW-approved battery charger to the vehicle and connecting the programming system (ISTA 4). The technician will then follow a measures plan to program, encode, and enable the relevant control units.
4. Post-Programming: After the software update, a rework list will be followed, a vehicle test performed, and any remaining faulty memory entries will be deleted. ISTA automatically handles the reprogramming and coding of all programmable control modules to ensure they have the latest software.

Required Tools or Parts

No new parts are required to perform this software update. However, the repair procedure necessitates the use of specific BMW diagnostic tools:

• ISTA 4 programming system
• A BMW-approved battery charger/power supply (refer to SI B04 23 10 for details).

Important Warnings

For technicians performing this repair, it is crucial to always connect a BMW-approved battery charger/power supply. This ensures stable voltage during the programming process, preventing potential issues.

Owner Action

If you own a 2024-2025 BMW X5 or 230i and are experiencing the BMW taillamp check control message, you should schedule an appointment with an authorized BMW dealer. The software update described in Service Information Bulletin SIB 63 07 25 will resolve this issue. This repair is typically covered under warranty as no parts are required, only a software update.
