Ok, finaly got time to try the elm on the car again
This is what i got :-



I also tried every other protocol and got: can.... error

looks like i might have to man up and take it to a garage to see if they can read the the cods/connect to my car.

 

That looks like you probably have a problem in the DLC (OBD's data link connector). It's not wonderfully accessible but you should be able to get at it to check the pins. If you can, unclip the whole DLC so you can check the wires from its rear as well as the pins. See what's on pins 2, 10 and 7. May as well post all the connected pins and wire colours.

16 should be batt+ (12V) and either/both of 4 & 5 should be GND (0V).

Could just be that it's not been used for 10+ years and is dirty or a pin has popped out/bent.

If you have access to an older Ford (roughly 1996-2005 but varies) they also used PWM (SCP) but the newer ones use CAN (as required by law). I used PWM with a 1996 Fiesta, for example.

GM (Vauxhall etc) use something else (VPW, when they did anything at all, and I hope now CAN) so no help. Many older cars use ISO or KWP.

 

ok, i'll see if i can get the dlc freed up tomorrow, it depennds how good my contortionist skills are and if i can control my ham fiistedness.

I''ll post backk the results.

Thanks

 

i didn't get home till after dark today will have a go in the morning

 

Any time at all, unless you're in a hurry.

BTW, JTIS should have troubleshooting info.

In case you're interested the DLC's wiring is shown in Section 20 (fig 20.1 on) of
http://www.captainjaguarscathouse.co...ec%20Guide.pdf

 

just downloaded that, thanks,, i'm gonna have a go at removiing the dlc tomorrow ( or get the wifes nimble fingers on the job) in daylight and if all wires/pins look ok think i might find a cheap garage to see if they can connect or not to rule out either my elm being faulty or my obd/dlc.

i just hate it when i cant do something / get something working !!!!!

 

+1 on that hate

 

Just triied to remove the obd dlc, everything on the s type seems to be screwed on wiith torx ? screws but not the dlc, it has tiny bolts smaller than the hexaganal part of a torx bit. i have nothing small enough to fit, tried some pliers, no joy, on the plus side it was actually quite easy to get my head under the dash and all the wires we firmly attached, i couldnt see what wire went to what pin but i pulled each wire and none were loose. i'll get some small socket bits and get it off before the weekend hopfully.

I suspect the elm my be faulty/clone checking the website i got it from it does not list Jaguar in the list of cars it works with, but neither does it list them in the list it does not work with.

ELM327 Scanner Software USB Interface - Free Shipping

Why is nothing ever simple ?

 

It looks the same as 2 I bought both of which worked fine with other cars, 1 of which uses the PWM I'm told your car has (and the Elec Guide shows).

The ad even says it does PWM although it has to if it's OBD II as it's required to support that.

It's a Ford protocol so if you have access to any Fords post which models & years and I'll try to find which are PWM.

 

No access to a ford vehicle.

I'll get the dlc out and make sure all conectionns are ok, when i was under the dash i could see which dlc conector/hole had a wire going to it, so if it still doesn't work i might try splicing into the wires and coonnect it to the elm that way, the were only about 6 wires going to the dlc (i can't remember exactly how many)

 

They should match the Elec Guide

JTIS will have troubleshooting for the signals I expect.

 

Hi,
I have the same ELM unit from Ebay and have it connected to my Blackberry. It will not read from my Cougars ECU but works fine on my wifes Suzuki. The Cougar is the same protocol as the non Canbus Jaguar AFAIK.

 

What model/year/engine/etc Cougar?

 

1999 2.5ltr Auto Cougar. But I am currently looking for a Diesel Jag S type.

 

I'll try to find its OBD details. (The 2.7D has yet a different PCM and OBD details, not shared with other S-Types.)

edit: looks like the Cougar is probably Ford's EEC-V PCM with PWM for OBD. That elm327 should work so if it doesn't it sounds to be faulty. (The Cougar also looks to have the HEC dash with crude diagnostics (*))

(*) press (RESET) and (UNITS) at the same time while turing on your car. Let go as the dials spin to the right. You scroll through the modes by pressing the (SELECT) Button

 

i did not find a sockket small enough to remove the bolts from the obd dlc to remov it, but while i was looking at it from below i could so which hole in the dlc had a wire going to it and every wire was secure and the ekm seems to make good contact. the were no loose / stray wires, all the obd wires went to the dlc.

I strongly susppect the elm is faulty / a clone.

I'm going to get an indy to see if they can connect and if so pull the codes, if the is any.

Ill post back the results

Thanks everyone for your help.

you get what you pay for, might be true afte all !!!!!!!

 

Well i sent an email to the company in hong kong i brought my elm ? from explaining the problem i had with it, thay pointed out that my vehicle was not listed in the compatable vehicles list, but offered me a credit note for the price of the elm and don't want me to return it.

This is the list of vehicles they say it iis compatable with.

I'm sure the are more cars than this that use OBD lol

No mercs, no vauxhall (GM) and only 1 ford using CAN !!!

Notice how all the vehicles listed use ISO or CAN protocol.

None listed use PWM protocol which the elm should support.

Looks like i got a cheap chineese clone.

 

The original ad you posted does list PWM! (I expect you noticed.)

This is bad news. Till now an elm327 was an elm327 and all did PWM (there was never a version that didn't).

You might try Gendan (here in the UK) and check if they say their elm327 does PWM. They seem an OK firm to deal with. I think it'll cost more, though.

 

I pointed that out to them (about it listing PWM in the list of specs).

Anyway i'm going to start a new thread look for a cheap (none elm clone) scan tool that works on pre facelift s types.

Genuine elm327's should work(i think) but untill you have it hooked up and try it the is no way knowing if it is genuine or not.

Damn you chineese counterfitters !!!!!

JagV8 i missed the bottom of your post, ill give them a try

 

Thats correct I do have a HEC dash which wrks fine but the elm doesnt work on it but works on other cars.
