Drive Inverter Warning: Vertical acceleration or yaw rate error
The drive inverter is not receiving vertical acceleration and/or yaw rate from the Restraint Control Module (RCM) properly, or their values are considered implausible. Alert log signal data for verticalAccel and yawRate should provide more information on the specific cause (frozen signal, signal rate limit exceeded, or CAN issue). Frozen signals or rate limits require further investigation. CAN issues should also be diagnosed and can be caused by the RCM not being on the PARTY CAN bus, or by general CAN bus error frames or shorts.
Traction control and stability control may be unavailable due to this error. The vehicle should be driven with extreme caution if these features are unavailable.
No
Drive Inverter (DI) does not receive proper front brake torque signals from the Electronic Stability Program (ESP) module.
The DI is receiving improper or implausible brake torque signals from the ESP. Check alert payload brake torque data for front left (brakeTorqueFrL) and front right (brakeTorqueFrR) to see the specific cause (frozen signal, signal rate limit exceeded, or CAN issue). CAN issues should be diagnosed and can be caused by the ESP not communicating on the PARTY CAN bus or general bus error frames or shorts.
Traction control and stability control may not operate as expected due to this error. The vehicle should be driven with extreme caution if these systems are not operating as expected.
No
Drive Inverter (DI) does not receive proper rear brake torque signals from the Electronic Stability Program (ESP) module.
The DI is receiving improper or implausible brake torque signals from the ESP. Check alert payload brake torque data for rear left (brakeTorqueReL) and rear right (brakeTorqueReR) to see the specific cause (frozen signal, signal rate limit exceeded, or CAN issue). CAN issues should be diagnosed and can be caused by the ESP not communicating on the PARTY CAN bus or general bus error frames or shorts.
Traction control and stability control may not operate as expected due to this error. The vehicle should be driven with extreme caution if these systems are not operating as expected.
No
The main Drive Interface (DI) is limiting torque to other drive units while one drive unit is engaged in spindown learning calibration routine, which selects either drive unit rotor learning (rotor flux and/or rotor offset) or resolver learning (error table) routines.
A drive unit reports it has entered spindown learning calibration state to the main Drive Interface (DI) while the vehicle is in Service Mode.
Only the drive unit engaged in spindown learning calibration responds to torque requests, limiting torque available from other drive units and power while driving.
No
The drive inverter (DI) electronic control unit (ECU) is unable to command a unit torque request to the rear drive inverter (DIR) ECU because the rear drive unit is disabled. This alert is set in addition to one or more DIR alert(s) indicating the reason why the rear drive unit is disabled.
At least one additional alert is present indicating the rear drive unit is disabled. Alert log signal data should provide more information on the specific condition(s) detected.
The rear drive unit may be disabled, which may prevent torque or power from being produced on the rear wheels.
No
Locking differential is engaged while disabled and requesting disengagement
Locking differential position sensor reports engaged or partially engaged when locking differential is disabled
A locked differential may reduce vehicle response to steering and increase braking distance.
No
The drive interface (DI) electronic control unit (ECU) detects a high voltage (HV) battery overcurrent event in software.
The DI ECU detects that the pack discharge current exceeds the limit for current platform.
Shift out of Park is blocked.
No
The drive interface (DI) electronic control unit (ECU) has limited vehicle speed for VERY HIGH ride height
The DI ECU sees VERY HIGH ride height
The vehicle speed is limited
No
Regenerative braking (regen) backfill braking torque is unavailable, requiring driver to apply brake pedal more frequently to decelerate / stop.
External Brake Request (EBR) or active damping is unavailable.
Drive inverter may not be able to supply the expected deceleration torque normally supplied by regenerative braking (regen) when braking. Driver will need to apply brake pedal more frequently to decelerate and stop.
No
The drive interface (DI) electronic control unit (ECU) detects that the Secondary Steering Feedback Actuator (SSFA) controller area network (CAN) node is missing (MIA).
The DI ECU is not receiving the expected CAN communication from the SSFA, and considers it irrational or MIA.
The DI ECU is unable to monitor the state of the SSFA.
No
The drive interface (DI) or drive inverter (DIx) electronic control unit (ECU) detects an analog-to-digital converter (ADC) channel reference above the upper rational bound.
Any ADC channel reference is above the maximum rational value.
The vehicle is blocked from shifting out of Park.
No
The drive interface (DI) or drive inverter (DIx) electronic control unit (ECU) detects an analog-to-digital converter (ADC) channel reference below the lower rational bound.
Any ADC channel reference is below the minimum rational value.
The vehicle is blocked from shifting out of Park.
No
The drive interface (DI) electronic control unit (ECU) detects a condition that affects Vehicle Hold.
The DI ECU detects a condition affecting Vehicle Hold. Alert log signal data provides information on the specific condition(s) detected.
Vehicle Hold may be unavailable.
No
One or more of the messages the Drive Inverter (DI) Electronic Control Unit (ECU) receives periodically from the Decoupled Power Brake (DPB) ECU is not received, indicating the DPB ECU may be unavailable (MIA).
One or more of the expected messages from the DPB ECU is not received.
There is no communication between the DPB and DI ECUs. This may impact traction and vehicle dynamics control performance. The vehicle should be driven with extreme caution if the traction or vehicle dynamics control systems are faulted.
No
Drive Inverter Warning: Rear 1 right drive unit disabled.
Fault detected in the rear drive unit
Unable to produce any torque or power on the rear wheels
No
The drive interface (DI) electronic control unit (ECU) detects that the Primary Electric Power Steering (PEPS) controller area network (CAN) node is missing (MIA).
The DI ECU is not receiving the expected CAN communication from the PEPS, and considers it irrational or MIA.
The DI ECU is unable to monitor the state of the PEPS.
No
The drive interface (DI) or drive inverter (DIx) electronic control unit (ECU) detects a low voltage (LV) battery power supply undervoltage event.
LV supply voltage to DI (refer to lvSupply) is disconnected or drops below lower voltage threshold
Drive unit enters unit limp mode (see DI_a126_limpMode)
No
The drive interface (DI) or drive inverter (DIx) electronic control unit (ECU) detects a low voltage (LV) battery overvoltage event.
LV supply voltage to DI exceeds the set upper voltage limit.
No immediate impact. Could damage drive inverter LV hardware if LV is continuously too high.
No
