WARNING: This page is about a different variant/trim than selected.
Use the scan tool data values under the following conditions:
- The DIAGNOSTIC SYSTEM CHECK - VEHICLE is complete.
- The On-Board Diagnostics are functioning properly.
- There are no diagnostic trouble codes (DTCs) present.
The values below represent a typical display recorded from a properly functioning system.
IMPORTANT:
Do not use a scan tool that displays faulty data. Report the condition to the scan tool manufacturer. The use of a faulty scan tool can result in misdiagnosis and the unnecessary replacement of parts.
Only the parameters listed below are used in this information for diagnosing. If a scan tool displays other parameters, the values are not recommended by General Motors for use in diagnosis.
Scan tool values below were recorded under the following conditions:
- Engine at idle
- Upper radiator hose hot
- Closed throttle
- Transmission in Park
- Closed Loop operation
- Accessories OFF
- Brake pedal not applied

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
