Alerts

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.

One or more of the BDW algorithms input signals is unavailable.

BDW attempted while car not in drive or input signals are being delayed

The absolute value of current difference between LVBMS_packCurrent and IBSCurrent exceeds nominal expectations

Incorrect battery current data being used, resulting in sub-optimal LV battery management.

Non-volatile memory misconfiguration or underlying flash/filesystem error.

Non-volatile memory records may be incorrect or missing.

The sleep bypass voltage is below 8V.

The load being precharged may not turn on. Vehicle functions relying on the load being precharged may not operate as expected. The vehicle may not sleep and will experience higher idle range loss

The LV battery type indicated by the GTW configuration value is an LV battery type not supported by this controller / firmware.

The LV battery system will not be updated to support the new configuration reported by the GTW configuration value. LV battery performance may be limited. LV battery support for vehicle electrical systems may be limited or unavailable.

Electronic Parking Brake Right detects high voltage lockout request timed out after 0.5 seconds

High Voltage control or contactor may be faulted

There is a sudden high power draw being observed on the VCLEFT that is outside of the defined operating threshold.

Vehicle may be unable to drive. Vehicle functions that depend on the VCLEFT (such as left side windows, doors, seat functions, and/or powered liftgate) may be unavailable or their performance may be affected.

The observed power draw on the VCRIGHT is outside of the defined operating threshold for too long.

Vehicle may be unable to drive and may start to power down. Vehicle functions that depend on the VCRIGHT (such as right side windows, doors, and/or seat functions) may be unavailable or their performance may be affected.

There is a sudden high power draw being observed on the VCRIGHT that is outside of the defined operating threshold.

Vehicle may be unable to drive and may start to power down. Vehicle functions that depend on the VCRIGHT (such as right side windows, doors, and/or seat functions) may be unavailable or their performance may be affected.

Estimated resistance on the input power feed to the vehicle controller is higher than expected.

The vehicle controller may be unavailable due to lack of adequate input power, limiting vehicle functionality or making the vehicle inoperable, with at least one other alert specific to that condition present.

The pump current profile is abnormal, or the purge routine is terminated before completion.

Cabin climate control system air conditioning may be limited or unavailable. Powertrain performance may be limited.

The VCFRONT detects an eFuse overcurrent event on the right headlight power feed.

The right headlight may be unavailable or may not function as expected.

The PCS is MIA when expected to be active on CAN, the LV battery is connected, the vehicle is not in service mode, and the vehicle is not being updated.

The PCS may be power cycled by the high voltage system.

The VCFRONT detects an eFuse overcurrent event on the left headlight power feed.

The left headlight may be unavailable or may not function as expected.

For both headlamps, the SSL100 pixel matrix detects non-functional pixels or has communication issues, or the voltage measured across the Lowbeam Prefield, DRL segments, or Turn LEDs (Model S only) is out of range, or the LED drivers in the ECU have reported status flags, or certain values programmed in the SSL100 EEPROM are out of range, or the fan current is out of range.

Certain light functions or the headlamp fan may be degraded or disabled for both headlamps.

An internal condition affecting the low beam (dipped beam) or high beam (main beam) LEDs, pixels, or the headlamp ECU's LED drivers is detected.

Right low beam (dipped beam) or high beam (main beam) may be partially or fully disabled.

Electronic Parking Brake has idle fault, or CSM_RQST_INVALID/CSM_RQST_NONE during retry or fault

Electronic Parking Brake caliper motor may be disconnected (idle fault), or no csm requests during retry/fault

The positive lead voltage measurement is lower than expected. The expected value is the lower of 16.5 volts, or the estimated PWM voltage.

Caliper motor or harness may be damaged

A condition is detected affecting switch functionality. Alert log signal data should provide more information on the switch affected and specific condition.

The switch may not function or may not function as expected.
