SMU - Revised DTCs B1000, B1004, B1007, B1009, B1013

This bulletin is being issued to revise DTCs B1000, B1004, B1007, B1009 and B1013 in the Body Control Systems sub-section of the Service Manual. Please replace the current information in the Service Manual with the following information.

The following information has been updated within SI2000. If you are using a paper version of this Service Manual, please make a reference to this bulletin on the affected page.

Although the diagnosis for these DTCs is found in the Body Control Systems sub-section, multiple modules on the vehicle may set these DTCs. Technicians have been replacing the Body Control Modules (BCM) even though the DTCs are retrieved as current from modules other than the BCM. The tables for the above-mentioned DTCs have been revised to clarify that the technician should replace the module setting the DTC as current (the table information remains the same, only the wording has been revised for clarification purposes).
