K114A Hybrid/EV Powertrain Control Module 1: Scan Tool Information
The hybrid powertrain control module is a non-serviceable module within the generator control module. The Hybrid Powertrain Control Module Scan Tool Data Parameters list contains hybrid controls-related parameters. The list is arranged in alphabetical order. A given parameter may appear in any one of the data lists, and in some cases may appear more than once, or in more than one data list in order to group certain related parameters together.
Use the Hybrid Powertrain Control Module Scan Tool Data Parameters list only after the following is determined:
- The Diagnostic System Check - Vehicle is completed.
- 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 Hybrid Powertrain Control Module Scan Tool Data Parameters list represents values that would be seen on a normally running vehicle.
NOTE:
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.
