Ok so i know this isn't a "third gen" question but i thought maybe someone could help me,so my question is if anyone knows where i could buy an OBD 1.5 connector for my equus innova 3140 OBD1/OBD2 code scanner?,i'm a mechanic that works out of my house and i get cars all the time that use the OBD1.5 but can never find the connector for it online,and if no one sells one can anyone give me a link to or good instructions on how to make one? i'm talking about a good detailed how to as in diagrams and all,any help would be great thanks

 

I got this off a corvette forum, maybe it will help:


Sequenced Code Recovery - 1994 through 1996:

In 1994, Chevrolet went to a 16 pin ALDL connector in preparation for the federally mandated change to the much more capable OBD-II (On Board Diagnostics - Version 2) system.

As with the 1990-1993 model, you can display codes on the speedometer but the pins to be shorted are different:

Beginning in 1994, you short pin "12" to pin "4" and once again turn the ignition switch to "On" without starting the engine.

The speedometer will display any codes using the same protocol as the 1990-1993 model but there are some changes in the designation for the modules plus additional modules are added:

Module "1" is still the CCM module.

Module "4" is now called the PCM module (Powertrain Control Module) because automatic transmission computer control was added to Engine Control Module in 1994.

Module 7 (on the 1996 model only) is the RTD module. (This is the Real Time Dampening module which replaced the Selective Ride Control module in 1996).

Module 9 is the ABS/ASR module number from 1994 through 1996.

Finally, Module "A", the DERM (Dynamic Energy Control Module --- the air bag control module) will be requested to show any codes.

Just like the 1990-1993 display, you read the codes on the speedometer and read the module number on the trip odometer.

Again, you can cause the codes to repeat by turning the ignition off for five seconds and then back on.

Turn the ignition off and remove the short to restore normal operation.

I also read a few posts that mention using the Actron CP9145 scan tool (an OBD2 tool), along with an additional cable that plugs up to the OBD1.5 configuration. I see these scanners as cheap as $50 on ebay, and the extra cable as cheap as $35.

I also read where the Actron CP9150 "Siuper Kit" is basically a CP9145 that comes with the CP9127 cable (and maybe others) that's needed (like Mopar cables and such). I see these CP9150's going on ebay for anywhere from $50 bid to $220 buy-it-now. Just search Actron CP9150.

But again - this is what I read off the internet - don't sue me if it's incorrect.

 

thanks camaronewbie this info helped a little,if i got the obd1.5 to usb could i take that and just cut the usb part off and splice on a serial port connector? i think my innova would read it i just don't want to have to buy a new scanner just for 1.5 ya know?

 

I'm no computer wiz, but I don't think that will work - USB is a completely different monster than a standard serial connection.

Besides, I didn't see anything about a OBD1.5 to USB anywhere. I did see "OBD2 to USB version 1.5 but that doesn't have anything to do with OBD1.5 - it's VERSION 1.5 of an adapter for a OBD2 cable connector.

But like I said, I'm no computer wiz. I just got curious about your question and I did an internet search for OBD1.5.

Good Luck!

 

yeah i found a OBD1.5 connector for laptop and its an OBD1.5 connector to USB but i didn't want to spend the $60 for the connector and then how ever much a serial is if it wasn't going to work
