|
The Right 24V STITCH EFuse current is reaching the Right 24V STITCH's max capability.
|
The Right 24V STITCH EFuse current is too close to Right 24V STITCH's max capability for 1s

|
The compressor power index is lower than expected, which typically indicates a condition affecting the compressor. This can also indicate a condition affecting the discharge or suction pressure sensors. The compressor power index measures the ratio of estimated nominal compressor power consumption against electrical power the compressor actually consumes. A low index value indicates the compressor is drawing / consuming significantly more power than a nominal compressor would be expected to consume.
|
The compressor power index, which compares expected compressor power consumption against actual consumption, drops below expected levels.
|
Thermal system may show reduced effectiveness. Cabin climate control performance may be limited, with cabin heating / cooling not performing at expected levels.
|
No
|
|
|
A condition affecting right front turn signal functionality has been detected - the right front turn signal may be degraded or disabled, and remaining right side turn signals will fast blink.
|
The headlamp ECU is MIA on LIN (not responding to Local Interconnect Network traffic) while powered on, or an internal condition with the turn signal LEDs or the headlamp ECU's LED driver is detected.
|
Right side turn signals will fast blink
|
No
|
|
|
One or more of the messages the vehicle controller receives periodically from the Center Console Control Module (CCCM) electronic control unit (ECU) is not received, indicating the CCCM ECU may be unavailable (MIA).

One or more of the expected messages from the CCCM ECU is not received.
|
Vehicle functionality depending on the CCCM ECU may be limited or unavailable.
|
No
|
|
|
A condition affecting right daytime running light (DRL) functionality has been detected - the right daytime running light may be degraded or disabled.
|
An internal condition with the daytime running light (DRL) LEDs or the headlamp ECU's LED driver is detected.
|
Right daytime running light (DRL) may be partially or fully disabled
|
No
|
|
|
One or more of the messages the vehicle controller receives periodically from the 2nd row right seat body controller (BCS2R) is not received, indicating the BCS2R may be unavailable (MIA).
|
One or more of the expected messages from the BCS2R is not received.
|
2nd row right seat features depending on BCS2R functionality, including seat buckle and heating pad, may be limited or unavailable.
|
No
|
|
|
The vehicle controller(s) controlling the headlamps have commanded the headlights to adjust to a beam pattern that is optimized for left-hand traffic as the vehicle is now located in a region with left-hand traffic.
|
The vehicle is now located in a region with left-hand traffic, meaning vehicles are being driven on the left side of the road.
|
Headlight illumination will be optimized for regions with left-hand traffic.
|
No
|
|
|
One or more expected Controller Area Network (CAN) messages from the Body Controller - Front Passenger Door (BCFPM) electronic control unit (ECU) was not received. The front passenger side door may not function as expected.
|
An expected CAN message from the Body Controller - Front Passenger Door (BCFPM) electronic control unit (ECU) has not been received within the expected timeout, or the message drop rate is too high while the BCFPM is CAN active. The ECU is considered CAN active when VCFRONT_vehGoToSleep is 0.
|
The front passenger side door may not function as expected.
|
No
|
|
|
A condition affecting right front side marker functionality (small amber light at top corner of headlamp) has been detected - the right front side marker may be degraded or disabled.
|
An internal condition with the right side marker LEDs or the headlamp ECU's LED driver is detected.
|
The right side marker may not be illuminating.
|
No
|
|
|
The eFuse application-specific integrated circuit (ASIC) on the vehicle controller is in an unexpected state.
|
Vehicle controller eFuse ASIC is not in the requested state
|
Vehicle Controller eFuse ASIC may not turn on or off as expected
|
No

|
The vehicle detects at least two of the following: low flow index at high subcool on either Chiller Only or Evap Only modes or abnormally low suction superheat.
|
The thermal system may not perform as expected and the electronic expansion valves (EXV) will open wider to accommodate the air bubbles in the system.
