| Signal Name | Description | Condition | Impact |
|---|---|---|---|
|
The vehicle controller detects the vehicle is not factory gated or the coolant is not filled, causing the coolant pumps to turn off and the coolant valve to be in Series or No Bypass mode.
|
May set due to any of the following: (1) vehicle is not factory gated; (2) coolant is not filled; (3) coolant fill / drain routine is active.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
Battery coolant pumps will not operate while restarting.
|
Battery coolant pumps have recovered from a fault, and is restarting
|
Powertrain performance will be limited, coolant flow will be reduced.
|
|
|
Frunk latch under current.
|
Frunk latch drawing less current than expected.
|
Frunk latch may be disconnected.
|
|
|
A fault has been detected with the right tail light.
|
The right tail light driver has reported a fault.
|
The right tail light may not be working.
|
|
|
Chiller coolant pumps will not operate while restarting.
|
Chiller coolant pumps have recovered from a fault, and is restarting
|
Powertrain performance will be limited, coolant flow will be reduced.
|
|
|
Frunk failed to open.
|
Latch does not indicate release after being commanded to actuate.
|
Frunk may not have opened
|
|
|
Frunk latch over current.
|
Frunk latch drawing more current than expected.
|
Frunk latch may be shorted.
|
|
|
Powertrain coolant pumps will not operate while restarting.
|
Powertrain coolant pumps have recovered from a fault, and is restarting
|
Powertrain performance will be limited, coolant flow will be reduced.
|
|
|
The vehicle controller detects the vehicle is not factory gated or the refrigerant is not filled, causing the compressor to be unavailable and the refrigerant valves (solenoid or electronic expansion valves (EXV)) to remain open.
|
May set due to any of the following: (1) vehicle is not factory gated; (2) refrigerant is not filled; (3) refrigerant fill / drain routine is active.
|
Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.
|
|
|
There is an unexpected condition affecting a VNF1048 chip.
|
The VNF1048 chip reports a condition affecting its operation.
|
Affected eFuse may not be on.
|
|
|
Radiator coolant pumps will not operate while restarting.
|
Radiator coolant pumps have recovered from a fault, and is restarting
|
Powertrain performance will be limited, coolant flow will be reduced.
|
|
|
A fault has been detected with the right rear turn or brake light.
|
The right rear turn or brake light driver has reported a fault.
|
The right rear turn or brake light may not be working.
|
|
|
The thermal fan demand was limited due to phase over current. HVAC cabin cooling (air conditioning) and powertrain performance may be limited.
|
The thermal fan detected that its enable pin went low unexpectedly during normal operation and the fan demand is limited as a result.
|
HVAC cabin cooling (air conditioning) and powertrain performance may be limited.
|
|
|
The coolant valve actuator is clocked incorrectly on the valve. Re-install the coolant valve. Powertrain performance may be limited.
|
Powertrain thermal performance indicates the 5-way valve is installed incorrectly.
|
Powertrain performance may be limited.
|
|
|
Front trunk (frunk) latch status suggests that the frunk switches are not correctly reporting the latch status. Latch may require replecement.
|
Controller determines frunk latch switches are not reporting correctly based on recent frunk release and switch interactions.
|
The frunk latch switches may not report the correct status. The frunk latch switches may report closed when the latch is physically open.
|
|
|
