Notice: Do not use a scan tool that displays faulty data. Report the scan tool problem to the manufacturer. Use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.
This scan tool provides the following capabilities:
| • | Read the data list. |
| • | Read the current ant history trouble codes. |
| • | Clear the diagnostic trouble codes (DTC) after a repair is completed. |
Ensure that the scan tool has current software before attempting repairs with the vehicle. Refer to the scan tool users guide for additional information and operating instructions.
The scan tool data displays specific module information pertinent to the system. The scan tool data display contains scan tool values from a properly operating system. Use this data as a reference after you have ensured that no DTCs are set and the Passlock™ system check procedure is performed.
Only the parameters listed in the typical scan tool data display are referenced in the service manual for use in diagnosis. If all of the values are within the typical range described, refer to Intermittents and Poor Connections Diagnosis in Wiring Systems.
