| N202317390 01 | 2021-02-16. Service bulletin. AIR BAGS; EXTERIOR LIGHTING; SEATS; ELECTRICAL SYSTEM; VEHICLE SPEED CONTROL. Customer Satisfaction Program (Revised Service Procedure). Certain vehicles may have a condition in which the brake system control module (BSCM) may set and latch an internal fault in the module?s on-board diagnostics (OBD) buffer. When the fault is present, no malfunction indicator lamp (MIL) is illuminated and there is no driver information center (DIC) message. If an over the air (OTA) software update is pushed to an OBD module and the customer accepts it through the Infotainment system, the update will fail because the presence of the active fault will block the OTA update. The customer may notice that the OTA update has failed with an error message on the DIC. This fault is not visible through dealer tools. Dealers are to reprogram the BSCM. |
