| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
One or more hardware conditions are present that require the vehicle trailer controller (VCTRAILER) to be powered off.
|
One or more hardware conditions are present that require the VCTRAILER to be powered off.
|
VCTRAILER will not be powered while the vehicle is not in Park (P).
|
|
|
Tailgate is closed but one latch is not fully secured (latched in the secondary position rather than primary).
|
Tailgate latch statuses indicate a combination of CLOSED and AJAR.
|
The tailgate might appear closed but may not have the same holding capacity as when both latches are fully closed.
|
|
|
The tailgate latch did not complete the actuation nominally.
|
The tailgate latch switches do not match their expected states at the end of an actuation.
|
The tailgate latch switches, harness, and/or latch mechanism may be degraded.
|
|
|
One or more loads failed to turn on during the Right Domain Undervoltage Self-Test. Those loads will be inhibited from use in drive.
|
One or more loads failed to turn on during the Right Domain Undervoltage Self-Test.
|
Impacted load(s) will not be usable in drive.
|
|
|
The Rear Domain Undervoltage self-test did not pass, as a condition affecting a load on the Rear Domain was detected during the self-test.
|
The Rear Domain Undervoltage self-test does not succeed. If a stuck-on or stuck-off condition is present, specific information can be found in the undervoltage self-test stuck-on or stuck-off debugging alerts.
|
The undervoltage protection circuit may not be functional.
|
|
|
The tailgate latch state transitioned from CLOSED without a motor actuation.
|
The tailgate latch state transitioned from CLOSED without a motor actuation.
|
The tailgate latch manual release may have been used, or the switches, harness, and/or latch mechanism may be degraded.
|
|
|
The tailgate latch motor drew less current than expected during an actuation.
|
The tailgate latch motor draws less than 200mA for over 250ms during an actuation.
|
The tailgate latch harness connection or motor may be degraded.
|
|
|
The eFuse application-specific integrated circuit (ASIC) on the vehicle controller has incorrect thresholds set.
|
The vehicle controller detects incorrect threshold values on its eFuse ASIC for 1 second.
|
The eFuse ASIC on the vehicle controller may not function as expected.
|
|
|
One or more of the expected CAN messages from Drive Inverter Rear Axle 1 Right (DIRE1R) were not received while in drive.
|
A message the local ECU expects to receive from the Drive Inverter Rear Axle 1 Right ECU (DIRE1R) hasn't been received within the expected timeout or the drop rate is too high while the DIRE1R is CAN active. The ECU is considered CAN active when VCLEFTS_vehGoToSleep is 0 AND VCLEFTS_vehiclePowerState is VEHICLE_POWER_STATE_DRIVE.
|
Drive functionality may be missing.
|
|
|
Rear height sensor disconnected, or signal line from rear Pulse Width Modulation (PWM) height sensor floating.
|
Rear height sensor disconnected, or signal line from rear PWM height sensor floating.
|
Air suspension leveling will be disabled. Systems with adaptive dampers will disable active damping control.
|
|
|
One or more of the expected CAN messages from Drive Inverter Rear Axle 2 (DIRE2) were not received while in drive.
|
A message the local ECU expects to receive from the Drive Inverter Rear Axle 2 ECU (DIRE2) hasn't been received within the expected timeout or the drop rate is too high while the DIRE2 is CAN active. The ECU is considered CAN active when VCLEFTS_vehGoToSleep is 0 AND VCLEFTS_vehiclePowerState is VEHICLE_POWER_STATE_DRIVE.
|
Drive functionality may be missing.
|
|
|
The super connector locking cover is disconnected.
|
The super connector locking cover is disconnected
|
Locking cover may not be connected
|
|
|
An internal condition affecting the rear light bar functionality has been detected - certain light functions may be degraded or disabled.
|
One or more lighting matrix managers report one or more conditions affecting their operation.
|
Certain light functions may be degraded or disabled.
|
|
|
The center high mounted stop light (CHMSL) is not communicating.
|
Loss of UART communication to the light.
|
The center high mounted stop light (CHMSL) does not operate as expected.
|
|
|
An internal condition affecting the center high mounted stop light (CHMSL) functionality has been detected - certain light functions may be degraded or disabled.
|
One or more lighting matrix managers report one or more internal conditions affecting their operation.
|
Certain light functions may not operate as expected.
|
|
|
One Electronic Parking Brake (EPB) not applied, and road grade is too steep to secure vehicle and trailer with only one EPB.
|
Only one Electronic Parking Brake (EPB) applied and grade too steep for one EPB to hold the vehicle with a trailer attached
|
Car may not be secured by Electronic Parking Brake on current road grade, may be free rolling
|
|
|
Road grade is too steep to secure vehicle and trailer with Park Brake.
|
Attempt to engage parking brake when vehicle with trailer is stopped on too steep a road grade for Electronic Parking Brake to secure the vehicle and trailer effectively
|
Car may not be secured by Electronic Parking Brake on the current road grade, may be free rolling
|
|
|
The air compressor for the air suspension system reports an overcurrent condition (current measurement is implausibly high).
|
The air compressor current measurement is above maximum rated operating current for an extended period.
|
The air compressor for the air suspension system is unavailable, making air suspension functionality limited or unavailable.
|
|
|
