Tech 1

[Brett_jjj]

For anyone interested, Ive found out some more stuff about Tech 1.I copied this off the web-
The are two versions of the Tech1 which were used by GM. The early ones are just a Tech1 the newer ones are known as the Tech1a. You can easily tell the difference. Tech1 has a 15way D PLUG and the Tech1a has a 26way HD (3 line) D SOCKET. The Tech1a also has a power socket and a RJ45 socket on the side for connecting to the RS232 port of a PC (the Tech1 requires an additional cartridge to add this functionality)

They are very much functionally identical for most tasks. The main difference is you cannot program a MSC (Mass Storage Cartridge) with a Tech1 unless you have the optional plug in communications module (with RJ45 socket). You also have to power the unit from the car (you can't power it on the bench!).Tech2 superseded the Tech1/1a . From what Ive read online on USA websites is that cars that have OBD11 plugs(16 pin) but use OBD1 protocols, eg VR/VS commodores ,need a special adapter,which apparently is still available in USA for $70US.

Hi,Just picked up the Tech1 I bought.It turned out to be a Tech 1A,happy about that.Anyone thinking of buying one of these for use on VR-VS should know that you definitely need an adaptor P/N 3000053,which is for a car that has sixteen pin obd2 plug,but uses obd1 protocol.The mass storage cartridge can be upgraded for different models at a holden dealer(if you can find one that will do it)and you can buy an obd2 interface to use on later models,not sure up to which model,VT onward uses obd2.Ive been looking through the manuals that came with it and this tool can do some mad ****,injector balances,pulse widths,heaps more stuff to numerous to write here.Id love to see a Tech 2 in action,the Tech 1 is mad enough.All I need now is the adaptor that I mentioned before, and I can use it.Im waiting on one from USA.Ive been playing around with it though,did a self test on it,(another different adaptor),all good.Checked out the different cartridges that came with it.I will keep anyone interested in this stuff up to date on what else I find out, here.

hi mate i was at holden the other day to clear an airbag error light, and the guy grabbed the tech2, then went 'oh its a vs' and went back and grabbed a tech1....

just confirming definetly tech1 is up to vs models, vt onwards is tech2

it doesn't look like the device that was used to program my two keys recently at Mr Minit (Thats how they spell it)

Does it have a provision for the key to plug into?

 

[Brett_jjj]

New keys are just put in the ignition,turned on and programming is done though the aldl connector with the scanner.You have to know your key/BCM number to do this.Mr Minit use the old key to partly program the new key,then all you do is use it to finish the process.

I still reckon that sounds like a score, even if the only thing you get out of it is the info. in the manuals. Love the GFC and an America in decline hey .

I found some more stuff for you:

Holden's 1988 ECM cartridge is Part # SD28229 (TK02310). That's for 1227808 ECM's i.e. VN, VP etc.

1991 BCM cartridge is TK02340. That's for VP BCM's, the connector for which is under the fuse cover on the RHS of the car, green ALDL connector.

Isuzu 87-91 TK02470A.

Isuzu 87-92 TK02470B.

Opel/Vauxhall 90-91 ECU cartridge is Part # 90 397 218.

The RS232 interface cartridge (Tech 1 only?) to connect to a printer, is TK05030A.

6-pin ALDL adaptor SD28180 (TA02329)

Isuzu/Hitachi 3-pin adaptor TA00018

Isuzu/Delco 3-pin adaptor TA02279B

Opel/Vauxhall 90-91 ECU 10-pin adaptor SD28224

The only thing I could find re. damage is on Jackaroo; only plug into a (the?) white ALDL connector.

Thanks mate,I have spent days searching the net for info,theres not much about it anywhere,so every bit helps,Thats why Im gonna post everything I find out about it ,so other people dont have to play the guessing game on what they need etc.Watch this space.Ive noticed the Tech2 is getting cheaper,seen one for sale in the USA that was on $1500US,(which is still not a practical amount to spend,unless your doing a lot of cars.Commodore Club etc),with candi module and 32mb memory card.When I looked again at it ,It was sold.Lasted about 10 mins, it was from a GM dealer that closed down.(Theres a lot of them closing at the moment over in USA.As Cheap6 said "GFC".).New, they are around $5000US .The candi module is around $600US.Theres a few tech 1s over there and are fairly cheap,you just gotta keep looking.I thought the homemade aldl reader I made was good,but These things are what you really want,I had no idea it could do so much stuff,I guess thats why GMH use em.One thing I cant find is the adaptor to connect a VN-VP ALDL connector to the tech 1.It must be only used here in Australia,theres not even anything on that plug overseas anywhere,(anyone here who works at holden might be able to get the part number for that adaptor,and post it on here for us ). If you could get the male plug that connects to the Vn,Vp aldl plug,you could probably make your own adaptor .A holden dealer might even be worth a try.I appreciate any bit of info anyone can find,Keep it coming ,and it will help others as well.
Thankyou, Brett.

Hi, For anyone interested, heres some stuff that can be done with a tech 1. This is from the tech 1 user manual. Theres pages and pages of stuff like this that can be checked , tested , monitored and changed.
This is just a small part of it.

Take snapshots of ECU at time of error code set.
Check injector balances
control idle speeds
clear or reset Block learn multiplier.
read system data
read trouble codes
command diagnostics
command field service mode
control air management
command fixed spark mode
control idle speed to minimum and calibrated positions while monitoring systems
shut off individual injectors
Command Program/Flash ECU.Flash EEPROM.

Turn on/off or override the following-
Torque converter clutch
1-4 shift solenoid
fan relays
engine hot warnings
air conditioner relays
canister purge solenoid
EGR solenoid
Dash gauges
ECM data monitored is-
Engine speed,reference pulses,coolant temp,oxygen sensor voltage,02 cross counts,injector pulse widths
Mixture control dwell,Air/fuel ratios,Air/fuel learned,spark advance,fuel intergrator,block learn,block
learn cell,rich/lean flag,02 sensor rich,02 sensor lean,02 sensor ready,wide open throttle,WOT divert,
engine hot,ALDL vote,open loop region,MD1,MD2,MD feedback,asynchronous pulse,temp switch,
MPG request, MPG reset,English/metric switch,First gear,second,third and forth gears,park/neutral,overdrive request

It can need different cartridges for some specialist tests. (sometimes, depending on what car its on)
I'm still waiting on an adaptor to connect it to my car, For anyone interested in this stuff I will post here what I find out when I get it connected. Hopefully this week. Cheers.

Also Im after an adaptor part number TA02329A, Connects the tech 1 to VN/VP commodores, will pay good money for one.PM me.

 

[moff_man]

tech 1 does up to vs with different cartridges
tech 2 does VT onwoards but also has a vs option in the list (maybe for later utes and statesman's)

tech 1 does real time data key programing security code checking (radio key etc)
not too much can be done on tech 1 compared to the latest tool's but still should do what you need it to do, IF YOU CAN GET THE RIGHT CARTRIDGES (he he i work at holden and i have access to them and no you can not have them)

Hi, I've already got them on the way. The one thing I do need is the VN/VP adaptor. P/N TA02329A .Theres also an OBD2 interface module that lets the Tech 1 talk to later models after the VT.Got it as well.Theres heaps of other stuff in the user manuals that I will put up here when I get a chance.There is nothing online about this stuff.Very hard to find out anything about it.Thankyou for your input.By the way you might be able to tell me something working at holden,Do you guys use I/F for rs232c to update or the T-100 connected to tech 15.And can the MS be updated from cd-rom.Also what happens to the used CD-Roms from the terminal .Thankyou.
