Signal Name Description Condition Impact Important
One or more expected Controller Area Network (CAN) messages from the Audio Digital Signal Processor (ADSP) electronic control unit (ECU) was not received. ADSP data from accelerometers may be unavailable.
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.
