ISO

The general flow with ISO Expert Mode (‘e’<3>), is:

1. Select a protocol (ISO 9141 or KWP 2000)

2. Setup filters for the messages you are interested in

3. Output some bytes and (optionally) wait for a designated number of response

bytes

The export mode commands to accomplish these tasks are:

Command ‘R’ – Set the Protocol Rate

Sent: 2 bytes

{

U8 Cmd; // ‘R’

U8 Rate; // 1=ISO 9141

// 2=KWP 2000

}

Responds: 1 byte

{

U8 Result; // Should match ‘Rate’ requested

}

Notes: Default is ISO 9141.

Command ‘r’ – Get the Protocol Rate

Sent: 1 byte

{

U8 Cmd; // ‘r’

}

Responds: 1 byte

{

U8 Result; // Current rate

// 1=ISO 9141

// 2=KWP 2000

}

Notes: The default rate when you enter this Expert Mode is ISO

9141.
