| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
The vehicle controller has determined the low voltage (LV) battery is no longer functional, as it has reached a low measured voltage with minimal Amp hours discharged.
|
The vehicle controller detects the LV battery has reached a low voltage with minimal Amp hours discharged. Alert log signal data should provide more information, including the load current, battery temperature, and voltage dip measured.
|
The LV battery may be unable to support the vehicle's electrical systems, or to successfully precharge the high voltage (HV) bus.
|
|
|
The overhead console experienced an internal condition affecting its operation. Its features may not operate as expected.
|
The overhead console is not responding over the Local Interconnect Network (LIN) due to an internal condition affecting its operation.
|
Overhead console, switches, lights or hazards may not operate as expected.
|
|
|
FL ride height sensor detected shorted or otherwise faulty. n/a to North American or Air Suspension eqiupped vehicles.
|
FL ride height sensor input pin shorted; input signal frequency above 840 Hz or below 760 Hz; input duty cycle above 87.5% or below 12.5%; input duty cycle changing too quickly (3300% / sec)
|
Headlamp leveling corrections blocked.
|
|
|
The vehicle has detected at least one electronic control unit (ECU) required for high voltage (HV) system operation running a firmware (software) version that may not be compatible with the firmware installed on the rest of the vehicle. When this occurs, the vehicle controller blocks HV battery contactors from closing and HV system from becoming active to make sure no ECU required for HV system operation is limited or unavailable due to firmware. May occur after an unsuccessful or incomplete firmware update, and may be resolved through a successful firmware update.
|
The vehicle detects at least one ECU required for HV system operation running a different firmware version than expected.
|
Vehicle is unable to drive, charge, or support the low voltage electrical system until the firmware version mismatch is resolved, to make sure no vehicle functionality required for HV system operation is limited or unavailable due to firmware.
|
|
|
Front Left (FL) ride height sensor is detected as unplugged or disconnected. When no signal is received from the sensor input pin, headlamp leveling corrections are blocked.
|
No signal has been detected on the Front Left (FL) ride height sensor input pin.
|
Headlamp leveling corrections are blocked.
|
|
|
A Battery Monitoring Board (BMB) device has detected an over voltage condition
|
Any BMB device in the daisy chain detects an over voltage condition
|
May indicate the battery pack is operating under unintended conditions. This alert may result in loss of pack power
|
|
|
Rear Left (RL) ride height sensor is detected as unplugged or disconnected. When no signal is received from the sensor input pin, headlamp leveling corrections are blocked.
|
No signal has been detected on the Rear Left (RL) ride height sensor input pin.
|
Headlamp leveling corrections are blocked.
|
|
|
RL ride height sensor detected shorted or otherwise faulty. n/a to North American or Air Suspension eqiupped vehicles.
|
RL ride height sensor input pin shorted; input signal frequency above 840 Hz or below 760 Hz; input duty cycle above 87.5% or below 12.5%; input duty cycle changing too quickly (3300% / second)
|
Headlamp leveling corrections blocked.

|
|
A fault has been detected with the left interior trunk light.
|
The light is unplugged, doesn't draw current when on, or its efuse is tripped
|
The left interior trunk light may not be working.
|
|
|
A fault has been detected with the left map pocket light.
|

|
Brake Switch Faulted: power rail (5V_MAIN_EXT) required for brake switch reads < 4.5V
|
Brake Switch Faulted: power rail (5V_MAIN_EXT) required for brake switch reads < 4.5V
|
Vehicle controllers will not be made aware of the brake being pressed
|
|
|
A side-view mirror started a fold or unfold movement, but then stalled before finishing the movement. The mirror will attempt 1 retry to complete the movement.
|
Sets if the mirror folding motor current exceeds 0.5A at some point, but then decreases to below 0.1A between 200ms - 1750ms after the beginning of actuation. Also sets at the end of the retry actuation to capture/log additional data.
|
The mirror will stop for 400ms before attempting the retry. If the mirror unexpectedly stalls again during the retry, it may be left partially folded/unfolded.
|
|
|
Mirror stalled unexpectedly while folding or unfolding
|
If folding motor current exceeds 0.5A or decreases below 0.1A after 500ms from beginning of actuation. Or timeout from current state after 5 seconds.
|
Mirror might be halfway between folded and unfolded
|
|
|

|
Battery Backed Siren not detected on LIN bus
|
Horn will sound instead of siren during an alarm event
|
|
|
Front exterior handle reported disconnected
|
Handle has just become reconnected or has been disconnected for longer than 1 second
|
If this alert persists the exterior handle may not work
|
|
|
Rear exterior handle reported disconnected
|
Handle has just become reconnected or has been disconnected for longer than 1 second
|
If this alert persists the exterior handle may not work
|
|
|
Unexpected voltage seen on window motor outputs. Window motors may be disabled
|
Voltage is above 8V for 200ms on at least one of the left window motor outputs while none of them are being driven
|
