Motor Control Module 1 Scan Tool Information

The Motor Control Module 1 Scan Tool Data Parameters list contains hybrid controls-related parameters. The list is arranged in alphabetical order.

Use the Motor Control Module 1 Scan Tool Data Parameters list only after the following is determined:

* The Diagnostic System Check - Vehicle Diagnostic System Check - Vehicle is completed.

* No diagnostic trouble codes (DTCs)

* On-board diagnostics are functioning properly

The scan tool values from a properly running vehicle may be used for comparison with the vehicle you are diagnosing. The Motor Control Module 1 Scan Tool Data Parameters list represents values that would be seen on a normally running vehicle.

Important:
A scan tool that displays faulty data should not be used. The scan tool concern should be reported to the manufacturer. Use of a faulty scan tool can result in misdiagnosis and unnecessary parts replacement.

Only the parameters listed below are referenced in this service manual for use in diagnosis. If all values are within the typical range described below, refer to Symptoms - Hybrid Controls for diagnosis.
