Hi,

I've bee trying this all day long. Double checked all the wiring a couple of times, is seems to be fine.

tried almost every possible combination of the delays. Also I've been trying this with two different serial ports - the one on the docking station of my thinkpad, and a USB/serial prolific dongle - both worked fine a lot of times with a lot of devices I'm working with.

Any advices what to look next. I can't wait for new cable, will have to make this one work.

this is what I get before the RX starts displaying 0,80,0,80 etc ...

I've checked almost every possible topic here and on the sourceforge forums too. I'm starting to think the OBD port of my RR is the problem

Any ideas ?

Well you've got further than me, I just get PP and that's it.

I've ruled out just about everything outside the car, so I'm just left with the OBDII port or the ECU itself, hopefully it's the port, I read about cleaning it with some wd40 and a tooth brush - I didn't have a toothbrush spare so used a nail brush with some wd40 but it made no difference, might be worth a try in your case?

 

[j1v]

yeah, today I'm going to check the obd on the car

 

[j1v]

Triple checked everything again, still nothing

Please help with any advises. I do reset the EAS with the initialize button (at least it seems so, every time the relay is clicking and the beeper beeps twice.

What else could be wrong ? Sometimes I receive 50s sometimes 54 .... not FFs at all ...

 

[j1v]

One more thing ? When the sync is lost, am I supposed to receive just "80"s ??? Becaus what I got is a sequence of 80,0,80,0 ... if that could be a clue to my problem ?

 

[j1v]

I've just attached a regular PC with hardware builtin serial ports and still nothing different as a result. All I got is 0,80,0,80 sequence instead of FFs - I guess that eliminates the port settings and dongle as a suspect, also the PC and OS.

Checked the cable even when plugged in the car's OBD ... the wires do make contact when I test between the rear end ov the vehicles obd connector and the rs232

Could I be totally wrong in understanding the wiring, or do my Rover has some kind of strange problem ? It's a 2.5 DSE p38, '96 .. if that matters. Software version in the about menu is 2.0 (rangerover_easunlock_suite_win32_10-20-08.exe) and the cable schema I use is from the menu of the software.

There is one more thing - on the OBD connector I've used pins 4 and 5 where connected. I've tried both with the default connected state, and later I've cut the link between them.

I'm desperately willing to solve that problem, please help

The OBD connecter on my cable also has pins 4 and 5 connected together, I wasn't worried though as they are both grounds, one is signal ground and the other is chassis ground.

You've done what my next test was going to be, which is to plug the cable in and test continuity between the back of the obdII port in the car and the rs232.

I've no idea but the software writer is a member on here, you could try PMing him or waiting to see if he comes along to help!

yes he is, and he wrote me yesterday with some advices, but unfortunately none of them worked. Hopefully he will notice this thread later. Meanwhile I've found two other users having the same problems in the past, but none of them provided a solution or at least, not mentioned there - viewtopic.php?p=275016#p275016

As I wrote in the other thread, solution is as follows:

i just figured out why i did get response with 3f not ff, problem was so easy and it was in front of me, but i was to dumb, but all my bright ideas comes in the morning, when im dieng from to much alkochol in yesterday party
so solution - im using Lithuanian regional seting, and u ppl using US regional seting, its . and , mater huray for me tonight im gona party for all hapy oweners with working eas system

10x for that man, after trying everything else, changing from bulgarian to english-us worked ...

 

[sotal]

Sorry forgot to mention that one, I had read about that and have mine set to US but still it doesn't work on mine, will hopefully test the port as soon as I get a min then I'll be a step further!

Thanks for updating the thread though and glad to hear you've got it working!

Cheers :thumb:

Sorry I have not been following the thread. Email is the best way to contact me. I can not browse the dozen or so forums that I am am member of. It would take hours.

When you have trouble getting FF in the Rx buffer;
First check the cable construction.
Check the USB to Serial Adapter configuration; See video on www.RSWsolutions.com website
Make sure vehicle is running
Adjust idle delay slightly
Inspect EAS Delay relay
Inspect OBDII port
Clean OBDII port

Has the vehicle ever had a coolant leak from the heater core? If Yes: Drop right hand footwell panel and inspect OBDII port.
I would not use WD40 to clean the OBDII port. Oil is a very good insulator.
And I have indeed heard of regional Windows settings interfearing with the comm port function. Although this has usually been from eastern countries.

And I have indeed heard of regional Windows settings interfearing with the comm port function. Although this has usually been from eastern countries.

I suppose it's got nothing to do with "interfearing"the comm port, most possibly somewhere in the source you're not using exactly "." or "," symbol, but "decimal symbol" as of windows, that is different in different country.

I suppose only changing of that in the regional settings would work and I'll give it a try, but that is still not a solution, the best way is to find that and fix it in the source. Or maybe at least add that problem to the FAQs on your website, I was about to surrender after trying almost everything for a couple of days.

Anyway, thank you for that great software, I finally have my car up and running.

Like I said, the problem was the regional settings of Windows. When I switched from "Bulgarian" to "English, US" everything worked like a charm !

j1v,

Sorry am a little out of tune,how do you change the regional settings of windows

start -> settings -> control panel -> regional settings

Thks Man, will try it out and see if something comes up.
