Yes, first post...here...
I hope like heck this isn't just a ricer's forum...a fart can muffler, CAI, and a resistor chip, along with an electric supercharger = instant 1,000 RWHP. Right?
NOT...

Anywho...Just what the title says...

Can anyone confirm that the '05 Vibe uses ISO-9141 for the OBD2 protocol rather than CAN like the later models do.

Also, does anyone have a list of active, retrievable Mode $01 PIDs? For that matter, any other non-standard PIDs in other modes?
 
Really?
Nobody knows the answer to this one?
Not one "hot rodder"? Not one "tuner"?
 
Did you try google?
 
Ya think?
Problem is, my particular Vibe has pins in the CAN AND ISO9141 positions, making identification by pin insertion alone impossible.

What say the masses now?

And you need to know this why? related to your shaky idle? based on what I see at genvibe you have done a lot of work but have you done a compression test?

I haven't done any work yet, which is why I haven't posted a specific thread about it yet. But yes, a compression check is also in the list.

The question is NOT why do I have a shaky idle.
The question WAS "Which protocol does the '05 Vibe use"?
A very simple question.
But apparently, for the fart-can muffler & CAI crowd, it's a brain-breaker.
 
No it's more like unless you have a specific need to know who cares. Typically you buy a scanner that covers the different types, you do have a scanner? That scanner than tells you all you need to know. Your attitude received the same reaction on the other site? Have you tried asking a GM dealer? Would love to see the face of the tech that has to answer your question. Guess you havent found the answer on the internet which even you must realize covers more than the slap something on the engine crowd.

No, I didn't buy a scanner. I built one. My design, my firmware, my...everything. (Google "mr. scanner obd", youtube hits, 5 parts, my 2nd version is a heck of a lot better/smaller/faster/more-options than the 1st version, but the jist of the story is still the same)
And yes, I did get my answer when the wife came home tonight and I was able to hook up to it.

Why wouldn't a real tech know the answer to that question?
After all...the guy (girl) should be "ASE Certified" right? They should know near everything about their particular specialty, right?

Why would a person have a specific need to know?
Off the top of my head, a LOT of the scanners sold on eBay don't support CAN. A person buys a cheap Chinese scanner and can't get it to work on a particular vehicle, they start troubleshooting the vehicle and not the scanner. Second, the ISO9141 is quite a bit slower than the rest (J1850PWM, J1850VPW, CAN, KWP2000, etc). In my case, I can use some trickery to speed up the response times of my scanner by doing some reprogramming at the expense of some functionality in other areas. Third, in my case, now that I know the vehicle "speaks ISO9141", I gotta dig into the wiring diagrams and figure out why there are also pins in the "CAN" slots, because they are NOT supposed to be there according to the OBD2 spec's.

I would further figure that there's got to be a handful of people out there doing some serious tuning and/or troubleshooting that also requires the daily use of a scanner of some sort to help that tuning...not that this particular engine is going to put out 400HP anytime soon.
But, again, from looking at the thread titles, apparently it's all about shiny parts...

Ok, stopped by the local Toyota and GM dealerships this morning.
Asked the service manager to ask the head tech "the question". "Steve" (not the head tech at Toyota dealer) and "Dan" (head tech at GM dealer) both came back with the right answers. Asked why I was asking, and replied with something to the effect of "ya, well any decent diagnostic tech should know that".
What say the masses now?
 
They say you answered your own question and we are happy you shared the results. Lots of luck in the New Year.
 
Aye...
I also went with the intention of trying to get some crossbars for my '05...thinking I might keep the money "local" vs. ordering out of state. No dice...at either dealer.

As far as the directly retrievable standard OBD2 PIDs for the '05 Vibe Base...
$00 - PIDs $00-$20
$01 - DTC info
$02 - Not available in Mode 1
$03 - Fuel System Status
$04 - Calculated Load Value
$05 - CTS
$06 - Short Term Trim Bank 1
$07 - Long Term Trim Bank 1
$0C - RPM
$0D - VSS
$0E - Advance
$0F - IAT
$10 - MAF
$11 - TPS
$13 - O2 sensors present
$15 - Bank 1 Sensor 2 Short Term Trim
$1C - OBD Standard
$20 - PIDs $21-$40
$21 - Distance traveled with MIL on
$24 - O2 sensor 1 Wide Range Lambda Ratio Voltage

What? No MAP? Haven't looked for it under the hood yet, haven't checked the extended PIDs to see if a value is available. Is this normal? This is the first vehicle I've owned without a MAP sensor.
