KWP Command Service IDs.

Note. This does not cover both the ‘Reserved’ range (0x87-0xB9) and ‘System supplier specific’ range (0xBA-0xBF)

Variants

StartDiagnosticSession

Start or change ECU diagnostic session mode.

ECUReset

Reset the ECU.

ClearDiagnosticInformation

Clears diagnostic information stored on the ECU.

ReadStatusOfDiagnosticTroubleCodes

Reads snapshot data of DTCs stored on the ECU.

ReadDiagnosticTroubleCodesByStatus

Reads DTCs stored on the ECU.

ReadECUIdentification

Reads ECU identification data.

ReadDataByLocalIdentifier

Reads data from the ECU using a local identifier.

ReadDataByIdentifier

Reads data from the ECU using a unique identifier.

ReadMemoryByAddress

Reads memory from the ECU by address.

SecurityAccess

Security access functions.

DisableNormalMessageTransmission

Disables normal CAN message transmission from an ECU.

EnableNormalMessageTransmission

Enables normal CAN message transmission from an ECU.

DynamicallyDefineLocalIdentifier

WriteDataByIdentifier

InputOutputControlByLocalIdentifier

StartRoutineByLocalIdentifier

Starts a ECU routine given a local identifier.

StopRoutineByLocalIdentifier

Stops a ECU routine given a local identifier.

RequestRoutineResultsByLocalIdentifier

requests results of an executed routine given a local identifier.

RequestDownload

RequestUpload

TransferData

RequestTransferExit

WriteDataByLocalIdentifier

WriteMemoryByAddress

TesterPresent

Tester present message. Kwp2000DiagnosticServer will automatically send this, so no need to manually create a message with this SID

ControlDTCSettings

ResponseOnEvent

CustomSid(u8)

Custom KWP2000 SID not part of the official specification

Trait Implementations

impl Clone for KWP2000Command

fn clone(&self) -> KWP2000Command

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KWP2000Command

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

Formats the value using the given formatter.

impl DiagnosticServer<KWP2000Command> for Kwp2000DiagnosticServer

fn execute_command_with_response(
    &mut self,
    sid: KWP2000Command,
    args: &[u8]
) -> DiagServerResult<Vec<u8>>

Send a command to the ECU, and receive its response

Parameters

• sid - The Service ID of the command
• args - The arguments for the service

Returns

If the function is successful, and the ECU responds with an OK response (Containing data), then the full ECU response is returned. The response will begin with the sid + 0x40

fn execute_command(
    &mut self,
    sid: KWP2000Command,
    args: &[u8]
) -> DiagServerResult<()>

Send a command to the ECU, but don’t receive a response

Parameters

• sid - The Service ID of the command
• args - The arguments for the service

fn send_byte_array(&mut self, arr: &[u8]) -> DiagServerResult<()>

Sends an arbitrary byte array to the ECU, and does not query response from the ECU

fn send_byte_array_with_response(
    &mut self,
    arr: &[u8]
) -> DiagServerResult<Vec<u8>>

Sends an arbitrary byte array to the ECU, and polls for the ECU’s response

fn set_repeat_count(&mut self, count: u32)

Sets the command retry counter

fn set_repeat_interval_count(&mut self, interval_ms: u32)

Sets the command retry interval

fn is_server_running(&self) -> bool

Returns true if the internal KWP2000 Server is running

impl From<KWP2000Command> for u8

fn from(cmd: KWP2000Command) -> Self

Converts to this type from the input type.

impl From<u8> for KWP2000Command

fn from(sid: u8) -> Self

Converts to this type from the input type.

impl Ord for KWP2000Command

fn cmp(&self, other: &KWP2000Command) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<KWP2000Command> for KWP2000Command

fn eq(&self, other: &KWP2000Command) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &KWP2000Command) -> bool

This method tests for !=.

impl PartialOrd<KWP2000Command> for KWP2000Command

fn partial_cmp(&self, other: &KWP2000Command) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
