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.

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.

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.

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.

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.

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.

The DI ECU sees VERY HIGH ride height

The vehicle speed is limited

The DI ECU detects that the pack discharge current exceeds the limit for current platform.

Shift out of Park is blocked.

Sensor output does not match rational reference

Traction control and stability control may fault due to this error. The vehicle should be driven with extreme caution if these sytems are faulted.

DI is not receiving required feedback CAN messages from DIRE1L

Unable to monitor DIRE1L state

One of Trail Assist's unavailable reasons appears while the feature is active

The DI will not allow Trail Assist until a safe state has been reached.

The DI ECU detects a condition affecting AEB. Alert log signal data provides information on the specific condition(s) detected.

AEB is unavailable.

DI is not receiving required feedback CAN messages from DIRE1R

Unable to monitor DIRE1R state

Fault detected in the front drive unit

Unable to produce any torque or power on the front wheels

At least one additional alert is present indicating the front drive unit is disabled. Alert log signal data should provide more information on the specific condition(s) detected.

The front drive unit may be disabled, which may prevent torque or power from being produced on the front wheels.

The DI ECU detects that no drive units are able to produce torque.

The drive system cannot produce any torque.

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.

The bootloader cyclic redundancy check (CRC) or application CRC is not expected, or the RAM constants do not match with initialization segment in flash.

The DI processor may reset, and other functionality may be impacted due to memory corruption.
