Motor Control Module 1 Scan Tool Information
Motor control module 1 is a non-serviceable module within the power inverter module, often referred to as the drive motor generator power inverter module assembly. 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 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.
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.
