  Summary

  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.

  Summary

  Service Update. On certain vehicles the clamp may not be properly aligned and positioned on the hose, or the hose is rolled over on the pump port. The improper assembly can quickly develop into a significant leak early in the truck?s life. As the coolant level drops, a Low Coolant Warning or potential for engine overheat with DIC message is possible. Dealers are to inspect for both the vertical and horizontal hose at the auxiliary coolant pump, and repair as needed.
