Signal Name Description Condition Impact
One or more of the expected CAN messages from the front drive inverter (DIF) was not received.
A message the local ECU expects to receive from the DIF ECU has not been received within the expected timeout or the drop rate is too high while the DIF is CAN active.
Drive functionality may be missing.
One or more expected controller area network (CAN) messages from the interior cabin radar (ICR) electronic control unit (ECU) was not received.
An expected CAN message from the ICR ECU has not been received within the expected timeout, or the CAN message drop rate is too high while the ICR is CAN active.
Intrusion alarm functionality may be missing.
One or more of the messages the vehicle controller receives periodically from the power conversion system (PCS) electronic control unit (ECU) is not received, indicating the PCS ECU may be unavailable (MIA).
One or more of the expected messages from the PCS ECU is not received.
The vehicle may be unable to charge.
One or more of the messages the vehicle controller receives periodically from the Tesla Air Suspension (TAS) electronic control unit (ECU) is not received, indicating the TAS ECU may be unavailable (MIA).
One or more of the expected messages from the TAS ECU is not received.
The air suspension may not function as expected.
One or more of the messages the vehicle controller receives periodically from the charge port (CP) electronic control unit (ECU) is not received, indicating the CP ECU may be unavailable (MIA).
The vehicle controller does not receive one or more of the expected messages from the CP ECU within the expected time frame.
Charging may not start or may be interrupted unexpectedly.
One or more of the messages the vehicle controller receives periodically from the Pedal Monitor (PM) electronic control unit (ECU) is not received, indicating the PM ECU may be unavailable (MIA).
One or more of the expected messages from the PM ECU is not received.
Vehicle speed and power may be limited.
More than half of the Electronic Control Units (ECUs) on either the Left CAN (LC) or Right CAN (RC) bus are missing more than half their messages while the bus should be active.
If 50% or more of the ECUs the local ECUs listens to are MIA, and the local ECU receives from more than 3 ECUs on this bus. An ECU is MIA if more than 50% of its messages are MIA and that ECU is considered CAN active (see specific ECU's MIA alert for CAN active conditions).
Vehicle functionality may not operate as expected.
One or more of the messages the vehicle controller receives periodically from the rear drive inverter (DIR) electronic control unit (ECU) is not received, indicating the DIR ECU may be unavailable (MIA).
One or more of the expected messages from the DIR ECU is not received.
Vehicle speed and power may be limited.
One or more of the expected CAN messages from iBooster were not received.
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.
One or more of the messages the vehicle controller receives periodically from the rear right drive inverter (DIRER) is not received, indicating the DIRER may be unavailable (MIA).
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 messages the vehicle controller receives periodically from the rear left drive inverter (DIREL) is not received, indicating the DIREL may be unavailable (MIA).
One or more of the expected messages from the DIREL is not received.
Vehicle speed and power may be limited.
A condition affecting switch functionality has been detected.
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.
A large voltage drop is detected in the input power to the vehicle controller, indicating the resistance on the input power feed to the vehicle controller is higher than expected.
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.
One or more of the expected controller area network (CAN) messages from the Autopilot Primary (APP) were not received.
A message the local ECU expects to receive from the APP ECU is not received within the expected timeout, or the drop rate is too high while the APP is CAN active.
Autopilot does not operate as expected.
An issue is indicated from the non-volatile memory manager.
Non-volatile memory misconfiguration or underlying flash/filesystem error.
Non-volatile memory records may be incorrect or missing.
Audio amplifier 2 reports an overcurrent error on one or more of its channels. This alert can indicate a condition affecting the amplifier hardware.
Amplifier 2 reports one or more of its channels is overcurrent.
One or more of the amplifier channels is not operating as expected. Audio will not operate as expected, and the amplifier may be shorted.
The amplifier reports an overcurrent error on one or more of its channels. This alert can indicate a condition affecting the amplifier hardware.
The amplifier reports one or more of its channels is overcurrent.
One or more of the amplifier channels is not operating as expected. Audio will not operate as expected, and the amplifier may be shorted.
The Ethernet Generalized Gateway (EGGxxx) detects a condition affecting the health of the second amplifier.
An amplifier condition is reported on second amp. Alert log signal data should provide more information on the specific condition(s) detected.
Audio quality may decrease.
A condition affecting Etherloop communication has been detected, such as a link down, electronic control unit (ECU) / switch down, or power domain issue.
Etherloop Generalized Gateway (EGG) has detected a condition affecting Etherloop communication.
Loss of communication redundancy or total loss of communication between some electronic control units (ECUs).
The signal quality of the Ethernet Generalized Gateway (EGG) clockwise Ethernet link to EGGLEFT is lower than expected and may result in packet loss.
The SQI of the EGG clockwise Ethernet link to EGGLEFT is less than 4.
The Ethernet packet loss affects the vehicle's functionality and performance.
