Struct ecu_diagnostics::kwp2000::KwpIOCTLManager

pub struct KwpIOCTLManager<'a> { /* private fields */ }

Handler for Input output control by local identifier requests (IOCTL) This allows for short term or long term actuation’s of components an ECU controls, or reporting a components current state.

USE WITH CAUTION!

Implementations

impl<'a> KwpIOCTLManager<'a>

pub fn new( identifier: u8, server: &'a mut DynamicDiagSession ) -> DiagServerResult<Self>

Creates an IOCTL manager

Parameters

• identifier - A identifier for the component or function to control. Valid ranges are
  • 0x10-0xF9 - Input output local Identifier
  • 0xFA-0xFE - System supplier specific
  • 0xFF - Input output local identifier Other values may result in an ECU rejecting the request.
• server - KWP2000 server reference

pub fn return_control_to_ecu(&self) -> DiagServerResult<()>

Asks the ECU to take back control of the identifier.

pub fn report_current_state(&self) -> DiagServerResult<Vec<u8>>

Asks the ECU to report the current state of the identifier.

pub fn reset_to_default_state(&self) -> DiagServerResult<()>

Asks the ECU to return the component identifier back to its default (Factory) state

pub fn freeze_current_state(&self) -> DiagServerResult<()>

Asks the ECU to freeze the current state of the identifier

pub fn short_term_actuate(&self, args: &[u8]) -> DiagServerResult<()>

Actuates the component at the provided identifier. This is a short term actuation. Once the ECU looses power or returns to its default session state, the component will be controlled by the ECU normally

pub fn long_term_adjust(&self, args: &[u8]) -> DiagServerResult<()>

Adjusts the component’s value. This is an optional command and is NOT supported by all ECUs. This allows for long-term adjustments (Such as fuel trims) to be made to the ECU. The ECU will retain the values even after a power reset.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
