Always refer to the GM Service Policy and Procedures Manual for the latest GM Policy and Procedures Information. General Motors Position on Aftermarket Power-Up Devices GDS 2 Software Updates and Screen Views General Motors does not support or endorse the use of devices or modifications that when installed, increase the engine horsepower and torque. This bulletin outlines the procedures to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine, transmission, transfer case or rear axle components, and before disassembly, repair or replacement of an engine, transmission, transfer case or rear axle assembly under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that an exhaust aftertreatment system component replacement is necessary. Various Symptoms Caused by an Aftermarket Power-Up Kit or Hardware • Poor performance. • Driveability concerns. • Increased emissions. • Knocking noise. • Engine damage. • Black smoke from the exhaust. This symptom may not occur if the diesel particulate filter (DPF) is in good working condition. The DPF will trap black exhaust smoke unless it is cracked, melted or has been removed from the exhaust system. Copyright 2014 General Motors LLC.
