Hello Mercedes,

It is more complicated then that. I do it differently.

Good News!!!
I just discovered today I can do Mazda CAN BUS system for Powertrain, ABS, Power Steering, Cluster, Transmission, and few others. 2003 up to I believe 2007. Powertrain appears Mode22. Like Mazda 3,6 and so on. This can hurt small software venders reputation if I pursue this. You understand what I am saying. What you think I should do?

johndoe,

I have a 2006 Toyota Tundra. Can you reverse engineer the pids for these sensors:

Humidity Sensor
Transmission Temperature
Room(Inside) Temperature Sensor
Outside Temperature Sensor
Remaining Oil Life
Fuel Level
Tire #1 air pressure
Tire #2 air pressure
Tire #3 air pressure
Tire #4 air pressure

silent_tiger85,
those are just descriptions, what are the PID’s for those???

johndoe,
how could you know what the pid’s mean if they dont have descriptions on the bus?? and, if i said i had a 2010 corolla (US) that has pid 220A on the bus how could you possibly know what that means (by “reverse engineering” it, etc)? mode-21 and mode-22 seem to be very proprietary pid’s and vary across manufacturers. so please explain this mystery reverse engineering you do.

2nd, i know piemmm said mode00 only works for mode-1 for “pid’s supported”, but for some implementations of OBD-2 (like EOBD) the ECU(s) should respond to a pid that gives “pid’s supported”. so i guess it’s best to start with querying 011C to see which implementation the ECU(s) is.

query pid ([mode][pid] for EOBD)
mode-1
0100 pid’s supported 1-20
0120 pid’s supported 21-40
0140 pid’s supported 41-60
0160 pid’s supported 61-80
0180 pid’s supported 81-A0
01A0 pid’s supported A1-C0
01C0 pid’s supported C1-E0

mode-5
0500 pid’s supported 1-20

mode-6
0600 pid’s supported 1-20
0611 pid’s supported 21-40
0623 pid’s supported 41-60
0634 pid’s supported 61-80
063D pid’s supported 81-A0
0648 pid’s supported A1-C0
065C pid’s supported C1-E0
065D pid’s supported E1-FF

mode-9
0900 pid’s supported 1-20

if anyone can add this this please do……

Yes, Toyota with and without CAN BUS can be done. I am not into Toyota at the moment.

Torquekid some things are better left unsaid.

By the way people, I can do 250 Mazda Powertrain Pids. Nice list!

Cylinder Temp: 221624
Desired Rpm: 22096E
EGR 1-4: 2216D2
Generator Monitor: 220939
Gear Status: 221101

I am throwing in few pids to prove my truth to you people. Equations and units are available as well.

What is your point in throwing teasers. If your motives are as you stated, and if you know all these PID and formulas, why don’t you just post them

Enjoy Silent.

there is also temp and many more. there is 2 type systems. choose 1 of them and see which works. I do not feel like doing anymore today.

Update: more pids added for tpms

Quote from johndoe on January 30, 2012
If anyone in here is interested in a pid post here and if available I will reply with the equation and name. Ford and Mazda is setup right now. Start with Powertrain. What sensors do you need?

OK, I’ll play

IAT2 on a 2012 Ford GT500. The one that worked up through 2010 no longer works. Can you find it? 😉

Can anybody get PID’s for a 2003 – 2006 Saab 9-3? Like Transmission temp, Gear position, or Misfires? The issue seems to be that you need Saab software with a TechII (GM Scan tool) to talk to those sensors. Just wondering if there is a workaround.

amdriven2liv,

07E0 22 096D
ecuID mode pid

this looks like a query to the specific ecu since ecu ID’s are 07E0-07E7 with response ID’s of ecuID+8.

SAEJ2190 seems odd, why mode-22 pid 0200 for DTC count? DTC count for standard public obd2 is mode-1 pid 0x01 returns 4bytes (ABCD), A0-A6 is binary for # of DTC’s, A7 indicates MIL light on or off.

What about PIDs for Dodge (Chrysler). They seem to be really hard to come by. Many of the PIDs that are selectable in a Tuner (such as the Predator) are not available within Torque (at least I did not see them). Things such as Engine Runtime and Knock ST Retard would be really handy.
