OK, im needing to "borrow" some ones vitara for a couple of hours. Jrzook being the smart cookie he is, is going to run some tests to see what signals the ECU from the 1.6 sends to the TCM for the AW4 auto. basically we just need to plug some probes into your wiring and see what signals come out. Happy to buy you a carton for your time.

PM me if you can help us out.

Willing to help with beer. Surely we have a thirsty vitara auto owner out there

If no one else comes fourth I should have mine registered next week.

ahh there we go, we have a winner!!!!

Are you sure that it is an AW4 and not an AW03 as described here:

That'd be an overseas variant no? Being a Suziki Sidekick.

The Sidekick is the US model but the TCM seems to have been used worldwide.

its the vitara one from here that were after. 4 speed auto. It gets called the AW4 but its not littlerally that number.

also chasing the TCM plug for one

AW4 = Asian Warner 4sp. Its not neccessarily the model number.

[tanshi]

Correct.

Though the model number for the JEEPs that used them was actually AW4 which i think is where it came from

Yeah, I spent loads of time searching for AW4 information and didn't find anything that properly matched the Zuk TCM.

If you only need a test connector then you can use a 26-pin connector from a 16V Vit ECU as long as you slice off the two outer polarization keys. The terminals are easy enough to remove if you need to swap their positions.

Really? I think I have a spare ECU plug in my ECU pile. Ill check it out!

James do you know if the firmware for the ECUs that came out in the manual vitaras support the auto TCM? There are output pins on the ECU socket but the plug just hasn't been populated.

right, that will give me another source for a plug if i can find one in a wrecker.

i have one that almost fits from my j20 wiring loom, so i guess they are similar

[Rhinoman]

Which ECU have you got? I'd have to have a look back through my notes but I don't think the 16V manual ECUs have the auto functions in the firmware, they don't usually have the components populated on the PCB but thats not to hard a retrofit.
The same ECU plugs were also used on Mazdas, Subarus and a few other Japanese cars as well as a bunch of other Zuks so you should be able to source one at a breakers easily enough.

Did you have any luck developing this ? I'm buying an AW4 for my zook in the hope that one of you smart cookies develop a way to make the AW4 work as stand alone or with an aftermarket computer (namely my haltech E6K).

I won't be able to use this auto until i (or someone else) figures this out

[tanshi]

Dans (jrzook) all over it. fingers crossed it works
