Symptom: The existing VCU and TCU software may cause various fault codes to be stored in the vehicle's fault memory. The TMU does not currently support WiFi connection capability. Discussion: If equipped, the updated VCU software adds ePTO enhancements, improvements to 12V and high-voltage battery conditioning, and eliminates erroneously stored faults. The TCU software improves the thermal management system and eliminates erroneously stored faults. The TMU software adds WiFi connection capability to the vehicle.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11016921-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11016921-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11016921","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"BOLLINGER MOTORS","model":"B4","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
