Hello all
I managed somehow to get the gear running again
And it's all good and I'm back to the main problem
The throttle won't respond to the acc pedal pressing
I had gotten a Bluetooth elm327 mini ode2 and connected it to the multiecuscan but I keep getting this error when testing the connection
COMMAND: ATSPC
The operation has timed out.
I tried various speed as I found on Google but nothing
Any help is appreciated
Thanks

Hi,
What computer and operating system are you using? Has the computer connected to the bluetooth device?

Robert G8RPI.

i use lenovo with win 10 x64 bit
i think it's connected as i get some passed test
i get like the photo attached (not mine but exactly the same except i have v2.1)
i used lm327 mini obd2 (bluetooth) like the one in the pic attached

Can you use MES to run the cooling fan..and fuel pump..??

That should be a good starting point.

can i do that without connecting ?
i couldn't connect to the ecu it says something like request time out
i noticed now that there is something in the body section like can info or something like that
but i didn't try to connect to it earlier
i just tried the gearbox and the engine ecu
i don't know if there will be any difference

i read somewhere in the net that it has some problem with win 10 but it was a single member who said that and the other was saying it's fine

i was considering running a virtual win 7 and trying MES from it but that's depends if i managed to get a usb bluetooth adapter

i'm just thinking in load voice don't mind me

thanks

Hi,
This sounds like a problem with a cheap interface. possibly due to the internal fitment of a 120 ohm terminating resistor between pins 6 and 14. Removing this resistor may help. You can tell if it's fitted by measurong between pins 6 and 14 of the interface with multimeter set to ohms.
If you have an android tablet or phone try downloading Torque and connecting with that.

i thought that too as they siad something like that in the MES site
but i was surprised to find that it was an official one after openning it
it has two 100 ohm resistors with capacitor before them (couldn't check the capacitor)
i tried it on a chivorolete pickup on the lite tourque app on the phone and it connected i don't know if this can help
but couldn't connect to my panda

and thank you for helping me here i really appreciate it

The resistor and capacitor termination was one "fix" that stops the DC load on the CAN bus but still loads the data signal. There is something more fundamental:
What year Panda do you have and what engine does it have?
The ATSPC command is trying to connect to the CAN bus with a custom profile and it's posssible you car does not support it. Was the car a used import or was it built for the Jordanian market? I was last in Jordan twenty years ago and there were many imports but I'm sure things have changed.

i have panda 2006 with 1.25 engine
in the MES it's named as panda 03' 1.2 8V and the engine control unit i think is magneti marelli iaw 4af/4ef/59f/5af injection (outside EU) as it's the only one having just 2 coils in the simulation (not sure)
any way i have bought this car about 3 months ago
i don't know it's origin if the chasis number helps i can provide it tomorrow
and it was working like a charm for 1 months then i had to do an overhoul for the engine because of the previous owner used oil was i think way past the exp date anyway
after that it worked fine for a month then i'm stuck with this problem for a month now
i think the problem happened maybe when they where trying to mount the engine as the have the gear left in place and when i was there the mechanic had a hard time mounting it and then he thought about taking the gear out then mounting it with the engine all together
any way he started to take the harness out then he told me that he can have a friend help him if i'm not in hurry and the next day it was done but i don't know what happened
any way i had it scaned that time a with a g2scan (i think that was it's name) and i rested the service and it worked great there was some error's and the recommendation was to change the clutch disc (the problem i had that time was the same problem i had from after a week from buying it and that it was the gear goes to natural while driving )
when i had my current problem i had one scan it and try to fix it and he said that the ecu is out and i need a new one
as he said that there was a tps problem and after changing the part the error still there and that means the ecu is out
but as i know there should be a problem in the harness when that happen so i took the car and started working with my self
i found some damaged wires and broken fuses , these where supposed to be found by the same guy who scanned it so i had no faith i decided to do it my self
and as i know the only thing they new about the scan is extracting error no live data
even the service rest i had a hard time convincing the guy to let me do it
they won't let me do the actuator test or something like that (it's very hard and if i need to work for a good time with it i had to have my device)
20 years ago i think fiat dealership was with the same company i work for now Abu Khader group
but now it's with another company and they said they don't work on this model as the devices the have won't connect (they said that on the phone when i called to book)
that's the whole story
if there is any fix for the elm327 i can do it no problem and i can upload the board pic tomorrow
thank you

Sorry can't help with the connection issue.
Early 1.2 Pandas had a throttle cable and a throttle potentiometer at the throttle body on the manifold.
Later ones were 'drive-by-wire', in that the throttle pedal was itself a potentiometer, and the ECU used its signal to power the throttle flap in the throttle body.
I think 2006 was the changeover year, so we need to know which yours is, to help with diagnosis, once we've sorted the connection issue.

If you've got a cable, an easy check is that it is connected, and properly. Might be this simple. Check the butterfly valve moves when the cable pulls.

If 'fly-by-wire', see if the butterfly moves when the throttle is pressed.

i think it's a fly-by-wire (see the attached photo)

there is some response when i press the gas pedal you can feel the car trying to go
but the rpm won't go higher that 2,5 even in N
and sometimes not higher than 1.5

one time i managed to drive it forward it was very slow and it drove for a bit then back to no response
a bit better when driving reverse (i think it has something to do with gear ratio)

and i noticed that the exhaust smells like the mixture is very rich and you can hear some weird voice in the engine like that misfire is occurring not sure of that i will record it next time

thanks

@jumahsafarty
This is quite a difficult situation. There are a number of variables:
We don't know te exact deatils of your car
Other people have worked on the car, possibly chainging things of damaging connections.
It's not certain the the ELM 327 interface you have works OK.

For the diagnostics there are three options to narrow down the issue:
1/ Try the interface and software on another Panda with the same engine
2/ Try a known good ELM 327 interface, preferably a USB one, on your car.
3/ Indentify the engine ECU and check the CAN bus wiring between the ECU and OBDII socket with a multimeter.

Unfortunatly all these need additional resources, 1/ A Panda, 2/ an interface and 3/ wiring information for the car, or at least the pinout for the ECU.
Can you get the part number of the ECU (what is written on the one actually in the car) for us easilly?

Off topic, I was in Jordan in 1996 and 1997 running a big black jet propelled car. The hospitality we received was great. This was in every sense as I actually needed surgery in '96 following an accident with a radio antenn mast. The only car dealer I saw was the Jaguar agent (one of the guys put low grade petrol in the supercharged Jag crash car wrecking the engine) who also sold licence built (Dacia?) Renault 12's.

ya it's quite hard to find another panda here
i was thinking about getting another usb interface but i didn't find anything already here
i have to order it and wait for it to be shipped to here which take usually a month
i can get the ecu number tomorrow
i was thinking about checking the wiring using the multimeter but i couldn't fine the diagram for the circuit
i'm thinking of trying with all the pins tomorrow thu

and i'm happy that you liked it here in jordan
i was barley born that time

thanks
i will update with all the new info tomorrow

Hi @jumahsafarty
With the ECU part number I should be able to tell you what pins t check between it and the OBDII connector. If you wanted I could get an interface for you and post it. The cost would be £27 (16.95 for interface and £10.05 for tracked postage) No idea how that compares to local prices.

The photo looks like one you've got off the internet. I was expecting a photo of your actual car. Are you certain the pic is like your car? Trying to avoid running in the wrong direction here.

Rather than trying to drive it, get the air cleaner off, then with engine switched on, but not running, operate the throttle pedal and see if the butterfly moves. Could also try with engine running, but actually look at it, rather than reporting from the driving seat.

Once MES is talking to the car, it will show the throttle movement, to confirm if the throttle potentiometer is working. The throttle potentiometer, at the pedal is a likely suspect. I think there have been similar threads on here.

Hello all
g8rpi
I really appreciate it
I will trouble you with sending one if the problem stay after checking the connectivity
The edu part number is iaw 5nf.s7
I have attached a photo of it
portland_bill
I had done what you said but there is no movement
The throttle doesn't move at all either engine on or off
I will search the threads and see what I got
I attached a photo of my throttle
The car was parked at the company I work for so I couldn't take pic of it yesterday as it was an off day

Thank you all

Sorry for slow response, it was a busy first day back at work. I've got the wiring diagrams and am working on a wiring pin to pin check list. The manual for the Panda is in the download section here:
https://www.fiatforum.com/downloads.php?do=download&downloadid=485
Having uncompressed it into a single file it had a .MXT file type. I had to change (rename) this to a .ISO before my CD burning software worked.
One other thing you could try on the connection front is if you have a "KL" type interface (also known as a VAG-COM for VW and Audi) you could try that. It connects directly to the Engine ECU, the ELM 327 defaults to CAN which goes via the body computer and ABS modules.
It is a fly by wire throttle so is looking like wiring or ECU issue. I'd be very wary about plugging a new ECU in without checking the wiring first as if a wiring fault has damaged the existing ECU it could do the same to the new one. I'll order an interface today, no obligation for you to buy it until I've checked it and it's ready to post.


Robert G8RPI.

g8rpi
thanks i had decided to get one and by you would be my best choice
i haven't done this before so when ready i will pm you (if there is no problem) for more details
i have installed the elearn and i'm really happy with it
hadn't gotten much time after installing it so i couldn't check the obd2 pins (i'm not sure if i'm fully understanding them either but with time it's manageable)
but i had checked one thing which has been on my mind from the start
i have checked the acc pedal and it's wiring and they are perfectly fine
i will try to check the obd2 wiring first thing tomorrow and i think i will check the throttle potentiometer
i hope it's just a wiring issue
thanks

Hi @jumahsafarty
Interface is ordered, it's this one http://www.ebay.co.uk/itm/271275445368
Please PM your postal address.
The CAN connections go from the Engine ECU to the ABS, to the Body computer and then to the OBDII socket. Pins 6 and 14 go to pins 11 and 20 of the body computer.
If you can;t connect to the body computer you can't connect ot the engine.
