Scan Tool Data List
Use the Scan Tool Data List under the following conditions:
- The Diagnostic System Check - Vehicle is complete.
- The on-board diagnostics are functioning properly.
- No diagnostic trouble codes (DTCs) are 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 manual 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
