Alerts

The Supermanifold Vehicle Controller (VCSUPER) does not receive expected messages from the chiller pump controller over the LIN.

The chiller pump controls will not function as expected.

For at least 10.5 seconds, the powertrain pump motor's RPM feedback is less than 800 RPM, or the powertrain pump motor is intermittently or continually given a non-zero flow request.

Powertrain performance may be limited.

One or more expected CAN messages from the ADSP is not successfully received. May be due to missing message(s), message reception rate error, or invalid checksum / counter error (message is too short / long, the checksum does not match, or unexpected sequence errors are present).

Air suspension functionality may be reduced. Excessive leveling corrections may occur. Active damping control may be disabled.

The refrigerant liquid temperature sensor reads a power rail or ground reference voltage.

Cabin climate control system air conditioning and heating may be limited or unavailable. Powertrain performance may be limited.

The chiller EXV motor driver is reporting an electrical condition (short or disconnect).

Cabin climate control system air conditioning and heating may be limited or unavailable. Powertrain performance may be limited.

The evaporator EXV motor driver is reporting an electrical condition (short or disconnect).

Cabin climate control system air conditioning and heating may be limited or unavailable. Powertrain performance may be limited.

One or more of the expected messages from the DIRER is not received.

Vehicle speed and power may be limited.

One or more of the expected messages from the HVP ECU is not received.

Vehicle may be unable to drive. Charging may be limited or unavailable.

Non-volatile memory misconfiguration or underlying flash/filesystem error.

Non-volatile memory records may be incorrect or missing.

Estimated resistance on the input power feed to the vehicle controller is higher than expected.

The vehicle controller may be unavailable due to lack of adequate input power, limiting vehicle functionality or making the vehicle inoperable, with at least one other alert specific to that condition present.

Rear left sensor reports pressure under region specific percentage of recommended cold pressure (RCP)

TPMS telltale and poor vehicle performance

Front right sensor reports pressure under region specific percentage of recommended cold pressure (RCP)

TPMS telltale and poor vehicle performance

One or more of the expected messages from the DIREL is not received.

Vehicle speed and power may be limited.

A condition is detected affecting switch functionality. Alert log signal data should provide more information on the switch affected and specific condition.

The switch may not function or may not function as expected.

Sudden power loss.

Controller is MIA for some time.

A message the local ECU expects to receive from the iBooster ECU has not been received within the expected timeout or the drop rate is too high while the iBooster is CAN active.

Brake boost functionality may be missing.

The vehicle controller does not receive one or more of the expected messages from the EPBL ECU within the expected time frame.

The parking brake may be unavailable or may not function as expected.

One or more of the expected messages from the DIF ECU is not received.

Vehicle speed and power may be limited. Thermal management system features depending on DIF functionality may be limited or unavailable.

The vehicle controller does not receive one or more of the expected messages from the HVBMS ECU within the expected time frame.

The vehicle may be unable to drive or charge.

The vehicle controller does not receive one or more of the expected messages from the RCM within the expected time frame.

Vehicle functions that depend on the RCM may be unavailable or may not function as expected.
