# Service campaign B640425

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## Other bulletins for the same vehicles and component

- [B611826](/bulletins/11037531.md), 2026-09-28, Service bulletin: ELECTRICAL SYSTEM. Due to unfavorable software, the Storage Management Electronics \(SME\) will not show fault codes that trigger the Malfunction Indicator Lamp \(MIL\) when performing ISTA Service Function "Display Permanent SAE Fault Codes." As a result, workshops will have to identify SME\-specific permanent SAE \(emission related\) Diagnostic Trouble Codes \(DTCs\) stored in the vehicle during diagnosis or when preparing a vehicle for a State Emission Inspection and Maintenance through a workaround procedure.
- [B611526](/bulletins/11036455.md), 2026-08-28, Service campaign: ELECTRICAL SYSTEM. In vehicles equipped with the Roof Function Center “FZD‑21” variant, a quiescent‑current violation mayoccur if the system fails to enter sleep mode. When this sleep error is present, a remote software upgrade\(RSU\) may be aborted and the FZD can become degraded. The following Check Control Messages \(CCMs\) may be displayed: “Energy Management — Increased Energy Consumption While Parked.” “Software Upgrade Failed — Workshop Visit Required.”
- [B630526](/bulletins/11036381.md), 2026-08-27, Service bulletin: ELECTRICAL SYSTEM. After programming the vehicle via ISTA/RSUto I\-level …26\-03\-5xx, some of the interiorambient lighting strips \(arrows\) may begin tofail sporadically after a deep sleep cycle.
- [B651426](/bulletins/11034467.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM. The vehicle may experience various operational issues with Apple CarPlay Projected Modes such as: Dropped connections No automatic reconnection Display errors
- [B610126](/bulletins/11034462.md), 2026-07-03, Service bulletin: ELECTRICAL SYSTEM. During vehicle start\-up the Secure Element \(SE\) of the BCP may fail causing communication errors. TheCheck Control message “Drive carefully. Driving stabilisation.” will appear. In addition, the fault memoryentries below will be stored within 40 seconds of each other. ACSM: 02010A \- Coding: Coding data not qualified VIP: 02390A \- VIP control unit: Coding data not released, signature IB: 02290A \- DSC control unit: Coding data not released, signature HKFM: 020D0A \- HKFM: Coding data are not qualified
- [B120326](/bulletins/11034449.md), 2026-07-03, Warranty extension: ELECTRICAL SYSTEM. Due to an implementation error in various OBD diagnostics in the vehicle's control units, in very rare cases itmay happen that stored fault memory codes \(DTCs\) and the MIL \(warning light\) are not automaticallydeleted even though the underlying malfunction has already been rectified. This does not comply with the statutory OBD specifications.
- [B610324](/bulletins/11031576.md), 2026-04-27, Service bulletin: ELECTRICAL SYSTEM. Gen 5 BEV/PHEV vehicles may set the Combined Charging Unit \(CCU\) in programming abort due to no communication to the HV charge socket electronics.
