VEHICLE DESCRIPTION: CERTAIN PICKUP TRUCKS EQUIPPED WITH 6.6L DIESEL ENGINES FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 105, "HYDRAULIC AND ELECTRIC BRAKE SYSTEMS." THESE VEHICLES HAVE A BRAKE SYSTEM WARNING LIGHT IN THE INSTRUMENT CLUSTER THAT MAY NOT ILLUMINATE WHEN THE BRAKE FLUID IS LOW.

VEHICLE DESCRIPTION: CERTAIN 2-WHEEL DRIVE PICKUP TRUCKS FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS." THE PROBLEM WAS CAUSED BY A COMPUTER ERROR THAT RESULTED IN THE CERTIFICATION LABEL LISTING TIRE SIZE AND INFLATION PRESSURE INFORMATION THAT DIFFER FROM THE TIRE SIZE AND THE INFLATION PRESSURE INFORMATION FOR THE TIRES ON THE VEHICLE. IF THE VEHICLE OWNER OR SOMEONE SERVICING THE VEHICLE INFLATES THE TIRES ACCORDING TO THE PRESSURE SPECIFIED ON THE LABEL VERSUS THE APPROPRIATE PRESSURE FOR THE TIRES, THE TIRES COULD BE UNDER-INFLATED OR OVER-INFLATED DEPENDING ON THE TIRES MOUNTED ON THE VEHICLE.

| 11006621 | Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers. |

This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return. |
