Hybrid Powertrain Control Module 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.

| Low Voltage Circuit Current | Amps | Varies | This parameter displays the amount of current for the 12 volt battery as detected by the 14V power module. |
| Low Voltage Circuit Voltage | Volts | 14.5 | This parameter displays the actual voltage of the low voltage (12V) circuit as detected by the 14V power module. The 14V power module internal sensor detects voltage in a range from 0-25.5V. |
| Maximum Hybrid/EV Battery Module Temperature | °C (°F) | Varies | This parameter displays the temperature of the hybrid battery module with the highest temperature. |
| MIL Command | On/Off | Off | This parameter displays the command status to illuminate the malfunction indicator lamp (MIL) on the instrument cluster. |
| Minimum Hybrid/EV Battery Module Temperature | °C (°F) | Varies | This parameter displays the temperature of the hybrid battery module with the lowest temperature. |
| Minimum Hybrid/EV Battery Module Temperature | °C (°F) | Varies | This parameter displays the temperature of the hybrid battery module with the lowest temperature. |
| On-Board Jump Assist Counter | Counts | Varies | This parameter displays the on-board jump start counter which increments each time an on-board jump start is initiated. |
| On-Board Jump Assist Successful Crank Request Counter | Counts | Varies | This parameter displays the on-board jump start key crank counter which increments each time a successful key crank occurs. |
| On-Board Jump Start Disable Reasons | Not Requested; Key not in Run- Incorrect Power Mode; Faults Present; Counters Exceeded; Jump Start Time Out; High Voltage Battery Status; HV Battery Contactor not Closed; HV Battery Low Discharge Power; Trans Shift Lever Position not in Park; Loss of Communication; Jump Start Max Time Out; Jump Start Inactive Time Out; Crank Assist Timeout | Not Requested | This parameter displays the general operating condition that is inhibiting the on-board jump start feature. |
| On-Board Jump Start Status | Inactive; In Progress; Complete; System Power Mode; Disabled | Inactive | This parameter displays the following statuses of the On-board Jump Start feature:
|
| Power Mode | Off; Accessory; Run; Crank Request | Run | This parameter displays system power mode status as determined by ignition switch inputs to the power mode master. System power mode status should match the ignition switch position. |
| TCC/Cruise Control Brake Pedal Switch | Active/Inactive | This parameter displays that the undebounced/undefaulted state of the redundant discrete brake switch input to the hybrid powertrain control module indicates that the brake is applied. | |
| Torque Delivered Signal | (lb ft) | Varies | This parameter displays the Engine Actual Steady State Torque. |
| Vehicle Speed | km/h (mph) | 0 | This parameter displays the vehicle speed calculated from the transmission output speed. |
Hybrid Powertrain Control Module Scan Tool Output Controls
| OutputControl | Description |
|---|---|
| 14V Power Module Set Point | This control function is used to override the state of the 14V power module low voltage output. The level of the low voltage output is controlled by the value supplied for Regulation of Low Voltage. |
| Auto Start/Stop |
NOTE:
|
| Auxiliary Transmission Fluid Pump Relay | This control function is used to override the state of the auxiliary transmission fluid pump relay output by turning the relay ON and OFF. |
| Clear Secured High Voltage DTCs |
NOTE:
Perform the high voltage disable procedure and repair or replace damaged high voltage components as specified in the applicable diagnostic prior using this control.
|
| Drive Motor Coolant Pump Relay | This control function is used to override the state of the electric motor A coolant pump relay output by turning the relay ON and OFF. |
| Drive Motor Speed | This control function is used to override the state of electric motor in a hybrid/electric vehicle. The drive motor belt must be removed first in order for this to operate. |
| Hybrid/EV Battery Pack Cooling Fan | This control function is used to override the state of the power pack (hybrid battery) cooling fan. |
| ICE Only Mode | This control function allows the 14V power module to charge the 12volt battery, but disables hybrid functions. Normal Car is defined in which the engine only provides the propulsion to drive the vehicle while the operation of hybrid subsystem is limited to charging the 12V. Disabled features include hybrid deceleration fuel cutoff, hybrid regeneration, and ICE autostop. |
| OnBoard Jump Assist Counter Reset | This control function is used to allow a service technician to reset the Jump Assist parameter counter. |
