This DTC sets due to an internal BCM timing issue during the self-test process. This specific code has no customer impact and does not cause any drivability concerns or warning messages. Clearing DTC U211B:43:48, reprogramming the BCM, or replacing the BCM is unlikely to prevent this DTC from setting. This DTC does not trigger a condition covered under warranty. Note: This guidance only applies to U211B with the specific failure byte 43 in status 48. Any other trusted real-time operation network (TRON) DTCs or different failure bytes associated with U211B are still applicable and technicians must follow Workshop Manual (WSM) normal diagnostics for those DTCs.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11037569-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11037569-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11037569"},{"nhtsa_id":11018238,"type":"service_bulletin","type_name":"Service bulletin","date_added":"2025-05-13","date":"2025-05-12","document_id":"SSM 53759","mfr_campaign":null,"component":"UNKNOWN OR OTHER","summary":"After replacement of any TRON module, the gateway module (GWM) and the TRON capable modules can set diagnostic trouble codes (DTCs) U211A, U211B, U211C, U3034, U3035, U3036, U35D9, U35DA and/or U35DB if the secret authentication security keys are not aligned between the modules, a loss of communication is occurring between modules and/or a module is not responding.
