Test Description
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers on the diagnostic table.
- 4. This step verifies that the yaw rate sensor signal voltage is within normal operating range. Voltage outside the specified range prevents VSES initialization.
- 5. This step verifies that the lateral accelerometer signal voltage is within normal operating range. Voltage outside the specified range prevents VSES initialization.
- 6. This step verifies that the master cylinder pressure sensor signal voltage is within normal operating range. Voltage outside the specified range prevents VSES initialization. If you completed steps 1 through 7 and did not locate the malfunction, you must have overlooked something.
