CM_ "AMI CAN interface v2.2. CAN1: 500000 bit/s; CAN2: 250000 bit/s. Both use Classic CAN, identical IDs, parsing and task request capability. This file is CAN2; use AMI.dbc for CAN1. Frames are not bridged between buses. SDC fields follow SDC_ACQ_DAC.dbc VERSION 1.1. BMS consumed fields follow BmsMonitor-CANTest commit e65c95203d1689df05343775982d7e85bd782646. AMI_DrivetrainDisplay is a custom instrument input; native motor-controller protocols are not defined. No calibrated vehicle speed, task execution feedback or AMI heartbeat frame is defined.";
CM_ BU_ AMI "Instrument MCU. UART HMI task confirmation produces AMI_TaskRequest. Display values come from SDC, BMS and custom VCU display inputs.";
CM_ BU_ VCU "Logical task receiver and sender/adapter for custom drivetrain display data. Execution and safety interlocks are outside this interface.";
CM_ BU_ SDC_ACQ_DAC "Source of ADC, capture frequencies and raw PD0-PD14 states; both SDC CAN ports carry the same protocol.";
CM_ BU_ BMS "Logical BMS source. Source frame periods are not specified here; do not infer them from test traffic.";

CM_ BO_ 386 "Standard ID 0x182, DLC exactly 8, send every 100 ms. Three little-endian signed int16 values: torque permille, motor temperature in 0.1 degC, motor-controller MCU temperature in 0.1 degC. Byte 6 bits 0/1/2 are individual valid flags; bits 3..7 must be zero. Byte 7 is fixed version 1. Wrong DLC, frame type, version or reserved bits rejects the whole frame without refreshing timeout. Valid fields update white; invalid fields retain last value and turn grey. Source expires independently after 2000 ms. Display only, no motor torque actuation.";
CM_ SG_ 386 Torque_Permille "Signed -1000..1000 permille relative to sender-defined reference torque. Out-of-range marks only torque invalid; temperatures still update.";
CM_ SG_ 386 Motor_Temperature "Signed int16 raw tenths degC. Screen rounds to whole degC, halves away from zero.";
CM_ SG_ 386 MCU_Temperature "Sender-supplied motor-controller MCU/inverter temperature, not the AMI STM32 die temperature. Screen rounds to whole degC, halves away from zero.";
CM_ SG_ 386 Protocol_Version "Fixed 1, independent of AMI interface package version 2.2.";

CM_ BO_ 768 "Standard ID 0x300, DLC 8. Event-driven: one request on valid HMI task confirmation, none on cancel. Counter wraps at 255. Request is not proof of execution and is not SDC ASSI_Lamp_Set (0x6A5). No CAN application-level acknowledgement is defined. Route to ports with valid RX within 500 ms; if none, attempt both.";

CM_ SG_ 1697 Input_Voltage "On-wire uint16 mV, decoded in V. dash.lvbat uses 0.01 V integer display units: (raw_mV + 5) / 10. Source expires after 1500 ms.";
CM_ BO_ 1698 "Standard ID 0x6A2, DLC 8, 20 ms. Preserve Hz; wheel circumference and pulses per revolution are undefined, so AMI does not convert to km/h.";
CM_ BO_ 1700 "Standard ID 0x6A4, DLC 4. Response to a DAC command. AMI recognizes the frame but does not update a display value from it.";
CM_ BO_ 1702 "Standard ID 0x6A6, DLC 8. Sent at startup and on PD0-PD14 changes, not periodically. AMI stores raw state, change mask and timestamp. No mapping to named d0-d15 safety signals or normal polarity is defined.";
CM_ SG_ 1702 SDC_Input_State "Bit n maps directly to PDn for n=0..14. Bits 15 and 31 in the payload are unused.";
CM_ SG_ 1702 SDC_Changed_Mask "Bit n indicates PDn changed since the preceding GPIO status frame.";

CM_ BO_ 320 "Standard ID 0x140, DLC 8. AMI consumes only bytes 0..3: big-endian unsigned voltage and offset unsigned current. Other payload bytes are outside this DBC subset. Display rounds voltage/current to whole V/A; source expires after 2000 ms.";
CM_ SG_ 320 Pack_Current "Current = raw_uint16 * 0.1 - 500 A; raw 5000 is zero current. This is not a signed int16 field.";
CM_ BO_ 342 "Standard ID 0x156, DLC 8. Eight actual temperature channels. Raw 0xFF is invalid, not 215 degC. AMI takes the maximum of valid channels only; all invalid clears validity. Maximum is derived, not another on-wire signal. Source expires after 2000 ms.";
