The vehicle gateway (GTW) detects the Steering Wheel Controller (SWC) electronic control unit (ECU) is running a firmware version that may not be compatible with the firmware installed on the rest of the vehicle.
|
The GTW detects the SWC running a different firmware version than expected.
|
Features depending on SWC functionality, including steering wheel buttons and scroll wheel functions, may be limited or unavailable. Note: No expected impact to steering wheel airbag functionality based on this alert.
|

|
The vehicle gateway (GTW) detects the right Headlamp Control Module (HCMR) electronic control unit (ECU) is running a firmware version that may not be compatible with the firmware installed on the rest of the vehicle.
|
The GTW detects the HCMR running a different firmware version than expected.
|
Features depending on HCMR functionality, including headlights and turn signals, may be limited or unavailable.
|
|
|
The vehicle gateway (GTW) detects the left Headlamp Control Module (HCML) electronic control unit (ECU) is running a firmware version that may not be compatible with the firmware installed on the rest of the vehicle.
|
The GTW detects the HCML running a different firmware version than expected.
|
Features depending on HCML functionality, including headlights and turn signals, may be limited or unavailable.

One or more of the messages the vehicle Gateway (GTW) receives periodically from the Tegra chip in the instrument cluster (IC) is not received through the ethernet connection, indicating the Tegra chip may be unavailable (MIA). This alert is only applicable to vehicles equipped with Info-Tegra Infotainment hardware.
|
One or more of the expected messages from the Tegra chip is not received.
|
The instrument cluster may be blank or may not function as expected.
|
|
|
The vehicle gateway (GTW) is updating the software of an offboard charger, such as a mobile connector (UMC) or wall connector. These updates run when the vehicle has finished charging and the user is not interacting with it (prior to the vehicle going to sleep). Disconnecting the charge cable will abort the update process. If the update is incomplete, the vehicle will attempt to update the offboard charger again later when all update conditions are again met.
|
The GTW detects an offboard charger software update is in progress.
|
Vehicle will be unable to drive or charge while the offboard charger software update is in progress.

The vehicle gateway (GTW) detects its microSD card file system boot sector has become corrupted. The microSD card needs to be successfully formatted.
|
The GTW file system driver detects the microSD card file system boot sector as corrupted.
|
Controller area network (CAN) logs / logging and vehicle firmware updates will be unavailable. Previously stored logs will be lost due to file system corruption.
|
|
|
Due to product security concerns, the vehicle gateway (GTW) has blocked a unified diagnostic services (UDS) message that the infotainment system attempted to send via GTW over a controller area network (CAN) bus. May result from a UDS message not having correct permissions (not whitelisted), but may also indicate an attempt to penetrate product security via the infotainment processor.
|
The GTW receives a UDS message without adequate product security permissions (not whitelisted).
|
UDS communication may not function as expected. Diagnostic routine(s) may not complete successfully due to lack of communication.

|
The vehicle gateway (GTW) detects an abnormally high amount of message traffic on the Chassis (CH) controller area network (CAN) bus. May result from a specific electronic control unit (ECU) showing unusual level of CAN activity or due to an unexpected event causing higher message rate than expected from multiple ECUs.
|
The GTW detects the CH CAN bus has an abnormally high amount of message traffic (greater than 70% of maximum capacity, or bandwidth).
|
Some CAN messages sent over the CH bus may be dropped / not received. Features depending on communication over the CH bus may be limited or unavailable.

The vehicle gateway (GTW) detects an abnormally high amount of message traffic on the PARTY controller area network (CAN) bus. May result from a specific electronic control unit (ECU) showing unusual level of CAN activity or due to an unexpected event causing higher message rate than expected from multiple ECUs.
|
The GTW detects the PARTY CAN bus has an abnormally high amount of message traffic (greater than 70% of maximum capacity, or bandwidth).
|
Some CAN messages sent over the PARTY bus may be dropped / not received. Features depending on communication over the PARTY bus may be limited or unavailable.

The vehicle gateway (GTW) detects an abnormally high amount of message traffic on the Vehicle (VEH) controller area network (CAN) bus. May result from a specific electronic control unit (ECU) showing unusual level of CAN activity or due to an unexpected event causing higher message rate than expected from multiple ECUs.
|
The GTW detects the VEH CAN bus has an abnormally high amount of message traffic (greater than 70% of maximum capacity, or bandwidth).
|
Some CAN messages sent over the VEH bus may be dropped / not received. Features depending on communication over the VEH bus may be limited or unavailable.
