Command ‘t’ – Get Basic Emissions Status

Sent: 1 byte

{

U8 Cmd; // ‘t’

}

Responds: 5 bytes

{

U8 Count; // char count (norm. 4)

// or 0xFF for failure

U32 Status; // This is simply the 4 bytes

// from Mode 1, PID 1

}

Notes: This PID (mode 1 pid 1) just gives a simple overview of the

emissions tests and their current status. Of interest if

you live in California.

Command ‘c’ – Get Device Configuration

Sent: 1 byte

{

U8 Cmd; // ‘c’

}

Responds: 36 bytes

{

U8 Channels; // Number of channels (16 max)

U8 Protocol; // OBD-II protocol

// 0 = automatic

// 1 = can

// 2 = pwm

// 3 = vpw

// 4 = kwp

// 5 = iso

U16 NormPid[16]; // Table of ‘normalized’ PIDs

// to scan

U16 Flags; // Priority flags

}

Notes: This controls how the ECU is connected to, what channels

are scanned and put in MTS data packets, and how the values

are scanned. It should be noted that these are not ECU

pids, but abstracted, or ‘normalized’ PIDs. This is to

accommodate the limits of 10 bit channels, etc. in MTS. See

the separate section on understanding this configuration

for more information.
