Service bulletin B610324

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.

B6118262026-09-28. Service bulletin. 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.
B6305262026-08-27. Service bulletin. 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.

B1203262026-07-03. Warranty extension. 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.

Several complaints are possible: Vehicle does not start Gear cannot be engaged Various Check Control Messages Malfunction indicator lamp (MIL) on Several Check Control messages are possible: “It is possible to continue driving. High-voltage system.” “You can continue driving. Drivetrain.” “Restart not possible. Drivetrain fault.” “Call Roadside Assistance. Drivetrain failure.” “Information: Total error of vehicle.” The following fault memory entries are stored in the CCU: D796D9 - Message (- 0x91) not up-to-date, receiver CCU, transmitter EME D796DC - No message (- 0x91), receiver CCU, transmitter EME D796D8 - No message (- 0x91), receiver CCU, transmitter EME Other fault codes below may be stored in the EGS BA09B8 – Inverter, Voltage Sensor, 5V HV AUX: Out of range or open connection detected BA0A45 – ECU internal: Internal error of the synchronous serial data bus. Additional fault memory entries are possible. Similar fault memory entries indicating a missing EMEmessage (Traction E-Machine Electronic) can also be stored in other control units.
