OBD2

On-board diagnostics (OBD) provides vehicle self-diagnostic and reporting capabilities.
OBD2 functionality is typically required for vehicle homologation.

info

OBD2 is a premium feature not included in the standard (public) LYNX firmware.
Contact siliXcon to obtain an OEM firmware with OBD2 functionality enabled.

DTC Codes

Supported Diagnostic Trouble Codes (DTC) and their implementations:

DTC	Description	LYNX Implementation Details
P0120	Accelerator/Pedal Position Sensor/Switch "A" Circuit	Triggers when /acc/csc output is NaN
P0122	Accelerator/Pedal Position Sensor/Switch "A" Circuit Low	Requires /acc/asc/absmin to be non-zero Triggers when /acc/acc/in falls below absmin Also applies to /acc/asc_2
P0123	Accelerator/Pedal Position Sensor/Switch "A" Circuit High	Requires /acc/asc/absmax to be non-zero Triggers when /acc/acc/in exceeds absmax Also applies to /acc/asc_2
P0500	Vehicle Speed Sensor "A"	Reserved for future implementation
P0A1B	Drive Motor "A" Control Module	Triggers when /driver/error is non-zero
P0A2A	Drive Motor "A" Temperature Sensor Circuit	Motor sensor temperature failure Triggers when RThermistor > 50 kOhm or < 80 Ohm
P0A2F	Drive Motor "A" Over Temperature	Motor overtemperature - /driver/limit & 256 Requires configured and functioning motor sensor
P0A3C	Drive Motor "A" Inverter Over Temperature	Driver overtemperature condition - /driver/stat & 4
P0A3F	Drive Motor "A" Position Sensor Circuit	Motor sensor error - /driver/stat & 16
P0C05	Drive Motor "A" Phase U-V-W Circuit/Open	Phase B disconnection detected at startup
P0A9B	Hybrid Battery Temperature Sensor "A" Circuit	Triggers upon CAN BMS connection loss

note

Motor Sensor Error

• Some sin/cos sensors may have unreliable disconnection detection

PID Codes

Parameter IDs for diagnostic data:

PID	Description
0x05	Controller temperature [°C +40]
0x8D	Motor RPM [rpm * 100]
0x5B	Battery SOC [%]
