WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Because of normal system communications between the TDM and ECM, any theft deterrent B-codes must be diagnosed prior to the diagnosis of P-codes.
Program the theft deterrent module. Refer to Theft Deterrent Control Module Programming and Setup . The ECM should successfully complete the password learn and the vehicle should start.
- If the ECM does not complete the learn or vehicle starting remains disabled, replace the ECM.
