Showing 201–225 of 225
- VCBATT_a529 — Discnctd Battery State Unknown VCBATT_a529_discnctdBatteryStateUnknown The LV battery may or may not be connected to the vehicle controller
- VCBATT_a532 — Gtw MIA In Drive VCBATT_a532_gtwMIAInDrive GTW is detected to be MIA while in Drive Power State
- VCBATT_a533 — LV Battery Vitals VCBATT_a533_LVBatteryVitals Captures LV battery health data during firmware updates. The firmware update window (HV contactors open, LV battery sole power source) is the only repeatable, fleet-wide event where the battery runs unsupported under load. This alert instr…
- VCBATT_a540 — Left Fog Light Guide Light Fault VCBATT_a540_leftFogLightGuideLightFault An electrical error has been detected with the left fog light guide (white light pipe in front fascia that turns on along with fog light).
- VCBATT_a541 — LV Battery Charge OC Level1 VCBATT_a541_LVBatteryChargeOCLevel1 The low voltage battery management system (LVBMS) reports it has detected the charge current is above the maximum limit for the low voltage (LV) battery cells in their present condition.
- VCBATT_a544 — LV Battery Comms Bus Turned Off VCBATT_a544_LVBatteryCommsBusTurnedOff The vehicle controller has disabled communications over the bus that connects to the low voltage (LV) battery after detecting a condition (or conditions) that may cause the LV battery to become overdischarged. To avoid overdischarge that c…
- VCBATT_a545 — LV Battery Type Unknown VCBATT_a545_LVBatteryTypeUnknown The low voltage (LV) battery type detected on startup is unknown. This usually happens the first time a controller is powered on, or after non-volatile memory (NVM) corruption, which will be indicated by another alert.
- VCBATT_a546 — Left Low Or High Beam Light Condition VCBATT_a546_leftLowOrHighBeamLightCondition A condition affecting left low beam (dipped beam) or high beam (main beam) functionality has been detected - the left low beam or high beam may be degraded or disabled.
- VCBATT_a548 — HV Fault Load Shed VCBATT_a548_HVFaultLoadShed The low voltage (LV) battery is discharging, even though high voltage (HV) system support has been requested. Vehicle loadshedding will occur, and a separate alert will be present to indicate that condition.
- VCBATT_a550 — Ambient Temp Delta VCBATT_a550_ambientTempDelta The vehicle controller printed circuit board assembly (PCBA) temperature is much higher than ambient temperature
- VCBATT_a555 — LV Battery Cell Rebalancing VCBATT_a555_LVBatteryCellRebalancing The low voltage battery management system (LVBMS) reports it has detected a low voltage (LV) battery cell voltage imbalance and is attempting to rebalance the cell voltages. The vehicle will be kept awake to support the LV battery until th…
- VCBATT_a556 — False Trigger Of Discnctd Battery Test VCBATT_a556_falseTriggerOfDiscnctdBatteryTest The disconnected battery test was triggered falsely.
- VCBATT_a559 — LV Battery Low SOC VCBATT_a559_LVBatteryLowSOC The low voltage battery management system (LVBMS) reports the low voltage (LV) battery has a reduced state of charge (SOC), which may lead to the LVBMS opening the LV battery internal protection transistor (MOSFET).
- VCBATT_a561 — LVBMS eFuse Overtemperature VCBATT_a561_LVBMSEFuseOvertemperature The Low Voltage Battery Management System (LVBMS) detects high temperature at the low voltage (LV) battery MOSFET (internal protection transistor).
- VCBATT_a562 — LVBMS Module Overtemperature VCBATT_a562_LVBMSModuleOvertemperature The Low Voltage Battery Management System (LVBMS) detects that the low voltage (LV) battery pack is experiencing high temperatures.
- VCBATT_a566 — Left Front Turn Light Fault VCBATT_a566_leftFrontTurnLightFault A condition affecting left front turn signal functionality has been detected - the left front turn signal may be degraded or disabled, and remaining left side turn signals will fast blink
- VCBATT_a568 — Left Daytime Running Light Fault VCBATT_a568_leftDaytimeRunningLightFault A condition affecting left daytime running light (DRL) functionality has been detected - the left daytime running light may be degraded or disabled
- VCBATT_a579 — Left Headlight eFuse Trip VCBATT_a579_leftHeadlightEFuseTrip The vehicle battery controller (VCBATT) detects an eFuse overcurrent event (or a trip) on the left headlight power feed.
- VCBATT_a582 — Good For PCS Power Cycle VCBATT_a582_goodForPCSPowerCycle The vehicle controller (VC) identified the PCS is MIA and may be in need of a power cycle to be recovered. This alert indicates the low voltage (LV) battery is in good state to support this.
- VCBATT_a587 — External LV Power Supply VCBATT_a587_externalLVPowerSupply An external low voltage power supply is detected. LVBMS_packCurrent and IBSCurrent reading are significantly different.
- VCBATT_a588 — Left Headlamp Factory Fault VCBATT_a588_leftHeadlampFactoryFault At least one left headlamp fault has occurred since vehicle battery controller (VCBATT) was powered on in factory mode
- VCBATT_a589 — Power Consumption Info VCBATT_a589_powerConsumptionInfo Reports average HV and LV battery power consumption rate in watts for every vehicle power state.
- VCBATT_a595 — Voltage Sensor Mismatch VCBATT_a595_voltageSensorMismatch The voltage measurement reported by the LV battery does not match one or more voltage sensors on the associated vehicle controller (VC).
- VCBATT_a599 — LV Battery Type Unsupported VCBATT_a599_LVBatteryTypeUnsupported The low voltage (LV) battery type reported by the vehicle gateway (GTW) configuration is a battery type not supported by this controller / firmware.
- VCBATT_a600 — Current Sensor Mismatch VCBATT_a600_currentSensorMismatch The current measurement reported by the LV battery (LVBMS_packCurrent) does not match the current sensor on the vehicle controller LV battery feed (IBSCurrent).
