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. |
| • | 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 Hybrid Powertrain Control Module 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.

Total Brake Torque | -- | Varies | This parameter displays the total brake torque required when braking as determined by the electronic brake control module (EBCM). The parameter display range is -8192 to +8191.75 N·m. | ||||||||
TR Sw. | -- | Park or Neutral | This parameter displays the transmission gear as commanded by the hybrid powertrain control module (HPCM). Under normal operating conditions this parameter will indicate the position of the transmission manual shift shaft position switch, also referred to as the internal mode switch (IMS). When certain DTCs are set, the HPCM may disable propulsion by turning off the internal combustion engine (ICE) and the electric drive motor generators. This parameter will display Neutral if the HPCM has disabled propulsion. The parameter display range is Park, Reverse, Neutral, Drive 1/2/3/4 and Illegal Setting. | ||||||||
Transmission OSS | -- | 0 RPM | This parameter displays the revolutions per minute (RPM) of the transmission output shaft as determined by the TCM output speed sensor (OSS). The parameter display range is 0-8192 RPM. | ||||||||
Vehicle Speed | -- | 0 km/h (0 mph) | This parameter displays the vehicle speed as determined by the engine control module (ECM). The parameter display range is 0-255 km/h (0-158 mph). | ||||||||
Vehicle Speed | -- | No | This parameter displays the status of an Autostart Request or Autostop Inhibit due to vehicle speed that exceeds a threshold as monitored by the HPCM. The parameter display range is Yes, No. | ||||||||
VTD Password Learn Enabled | -- | No | This parameter indicates if learning of the immobilizer secret information is enabled. | ||||||||
VTD Security Info. Programmed | -- | Yes | This parameter indicates if the immobilizer secret information, e.g. powertrain pre-release password, powertrain secret key, has been programmed. | ||||||||
VTD System Status | -- | Released | This parameter displays the immobilizer system status as determined by the hybrid powertrain control module (HPCM). The parameter display range is Standby, Immobilized at Startup, Immobilized Due to No Response, Immobilized Due to Negative Response, Immobilized Due to Incorrect Response, Post Release, Pre Release and Released. | ||||||||
