PRELIMINARY INFORMATION
Subject:
Speedometer Needle Accuracy Information
Models:
2003-2013 Cadillac Escalade Models
2003-2013 Chevrolet Avalanche, Silverado, Suburban, Tahoe
2003-2013 GMC Sierra, Yukon Models
Condition/Concern
A customer may comment that their vehicle's speedometer needle appears to be inaccurate. The speedometer
needle is electrically operated by a stepper motor and there may be some variation in accuracy. Digital readout
devices, such as "Digital Speedometer" on the DIC, are direct readouts of the Vehicle Speed Sensor (VSS) and their
accuracy is much greater. Tire size, tread life and inflation may cause some variation in the readings.
Recommendation/Instructions
The specification for speedometer needle accuracy is +/- 2 MPH at any given speed when looking straight at the
needle.
