Technical Getting P080A and P1306 codes

[jrkitching]

Have you checked the integrity of the hatch wiring? This is an extremely common fault which can lead to an almost endless variety of electrical malfunctions. If there is a hardware fault in the wiring loom, no code reader can be trusted to give reliable information.

Can anyone tell me how to get real, accurate info for P1306 code?

Buy a licenced copy of MES.

Have you checked the integrity of the hatch wiring?

I did hint at checking all the lighting circuits.

The yellow triangle warning commonly tends to point to a problem with the lighting/bulb (along with a few other problems) and if there's a problem is the brake light or reversing light circuit the ECU could start thinking it needs to protect the Dualogic 'box (which it hasn't got).

Is there any accompanying message on the dash to go with the yellow triangle?

These are Powertrain codes, so they are probably stored in all ECU's not just ones fitted to Dualogics, so if it got screwy inputs from these circuits it's possible it might think that's what it needs to flag.

If it was a Dualogic, you'd think it would disable some functions in reverse or when the brakes were applied (if obviously wouldn't try to kickdown or change up when either circuits are active) and I would suspect it would get those inputs from those particular circuits themselves.

As the tailgate wiring is a known, best place to start.

The message is "stop & start inactive" (or "not available" - I can't remember) and the gear numbers don't show up.

The code reader/s you are using are not giving you the full codes you need to help solve your problem.

Looks to me that your car needs to have the neutral / gear position relearn procedure carried out.

A clue was that you said your selected gear wasn't showing up on your display-clearly if it normally does show what gear selected (even though it is manual gearbox) it must have a gear position indicator switch.

Frankly I find it silly the expense and added complexity gone to for the display to show what gear selected after the driver has moved the gear lever to select the gear but hey just my opinion!

So choices- find a dealer to fix it for you at great expense because they most likely haven't done it before and will charge you for the time to learn how to do it. Find a dealer and get a fixed price to do it, can't see that happening easily.
Find out how to do the neutral/gear position learning procedure yourself and what code reader system you need to do it.

MES may do it I don't know. please try and be more open minded toward MES it has helped a great deal of us do repairs that would have been uneconomical if we had been forced to involve main dealers.

Good luck

Thanks Jack, much appreciated. I think the whole "relearn" thing is something the car should do itself after disconnecting / reconnecting the battery and being driven for a bit - if the engine can do it why can't a gear position sensor do it!

I'd be more open to MES if it at least gave me some info that showed me it could actually talk in detail to a FIAT 500. It is going to be a total leap of faith at the moment, and it shouldn't be.

Have you used MES on a FIAT 500?

 

[jackwhoo]

No it cannot relearn the neutral position by disconnecting the battery for a while reconnecting the battery and driving it.
The procedure has to carried out using a compatable scan tool / correct software and lead.

If you can run mes in simulate mode for fiat 500 look to see if the neutral relearn is on there.
Let us know.

If you do have a scan tool read the live data to check the clutch position switch is operating correctly-if it is not the relearn procedure won't work.

I have not used mes on a 500

If the mil light is on you will have to get it the problem fixed before cars next mot. In meantime you can keep driving it no problem. The only thing that you should notice is a the stop start won't work.

Hi - I'm going to pull the trigger on the MES licence. The simulator DOES show clutch pedal learning, so it's worth the risk.

 

[BigCL]

I did it - bought the full MES licence, read the DTCs and got something entirely different. Then I told it to re-learn the clutch position and neutral, cleared the codes and they have stayed cleared. Stop/start and gear change "shift" messages have returned, wife is a happy bunny and I get a "super mechanic" cap!

Thanks all for your input. I am a MES convert now! :slayer::slayer::slayer:

 

[jackwhoo]

Well done .
What codes did you get?
I'm glad you are not having to tell us it didn't work.

Jack

 

[BigCL]

We got B1047-13 and U1734-87.

I'm glad you are not having to tell us it didn't work.

Me too.

After post #21 , if it hadn't worked, I'd have gone into hiding.

Hi all,
I have simillar problem. My start/stop stopped working shortly after I replaced snapped gear changing cable. After a while I decided to buy MES and sort this out. Pressed option to relearn neutral position. It says Completed but Status: Unknown. From that time I always get an error and check engine light plus info that start stop is unavailable. Trying to relearn doesn’t work. Sensor might work as when I removed it from location and turned to the end I get some different error so it knows it’s out of range.
Can someone help me to get rid of it?
Thanks
