Use the scan tool data list under the following conditions:
| • | The Powertrain On-Board Diagnostic (OBD) System Check is complete. |
| • | The on-board diagnostics are functioning properly. |
| • | No 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 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 |
