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.

Ignition ON, test for 4.75-5.15 volts between the 5-volt reference circuit and ground.

If less than 4.75 volts, test the 5-volt reference circuit to all position sensors for a short to ground or an open. If the circuit tests normal, replace the memory seat module.

If greater than 5.15 volts, test the 5-volt reference circuit to all position sensors or a short to voltage. If the circuit tests normal, replace the memory seat module.
