Circuit/System Testing

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.

Extended use of extremely high volume, especially in warm weather conditions, may induce this DTC. Under these conditions it may be normal for this DTC to set to prevent permanent damage to the amplifier circuitry. If DTC persists without excessive volume, replace the amplifier.
