Posted by Shane Gray on July 1, 2014, 3:23 pm

Year of Manufacture *: 2004

Hi,
I have this C3 in with the automatic manual box issue. It wont select neutral so wont start.
I have dec superscan that has all functions but does anyone know why you can reset counters?
There are no codes stored, It fails to select neutral in actuators on scan tool. Anybody know correct procedure to programming actuators in special functions?
Any help please?
Shane

Hello Shane, I can't answer any of your questions in relation to your superscan but there should be a reset procedure in the owners manual or you could try this http://www.ultracars.co.uk/citroen-c3-pluriel-sensodrive-reset-procedure/

I had one of these in with a similar issue and sometimes a power latch fault code st I red and other times no dtc's logged.

I narrowed it down to a poor battery state of charge even though the battery wasn't that old but constant short trips didn't give it much chance to recover from stoo starting etc.

fitted a better quality battery and all seemed well. Also I remember replacing the brake pedal switch (passenger side) as iirc abs logged this code.

Hi Shane
As mentioned above, the correct battery is critical
When reprogramming clutch and gearbox actuators, battery voltage is important- think it needs 12.6 at least from memory, you will need a battery support module (or a diesel car connected to yours with engine running)to program successfully, also when prompted, wait until the end of power latch(dash all shut down) this is essential to the success of the procedure.
Dec does it fine, I have done it many a time

Check gearbox ECU plugs for water ingress.

Hi mark,
Left the battery off over night and it reset. Carried out configuration and all worked, I've still got code p1795.
Checked for water ingress but all dry.
Any ideas what to do next ?

>>> P1795 gearbox information (coherence),<<<

Sorry to tell you the obvious but the TCM is receiving conflicting information, start by looking at some of the APP inputs.

Hi Mark,
Sorry to sound stupid put whats APP stand for.
Customer popped back this morning and said it struggled to select reverse on Saturday. Codes today P1795 G-box info (coherence). P1719 Gear selection coherence and P1766 selection actuator signal.
Any advice best way to go.

Hi Shane,

Can't help with your problem but APP is accelerator pedal position sensor

Hi,
Getting this back in next week so any ideas the best way of checking it.
I have fitted a new brake light switch and it has stopped flagging that code in engine and transmission. I have looked at the app sensor in live data and all looks good.
What next ?
My have to send him to Citroen!

Would be a good suggestion to scope test app sensor whilst comparing it to live data in engine ecu and gearbox ecu just incase a glitch is spotted on scope that live data refresh rate maybe missing.

unless uoir graphing thr data which maybe more accurate. I was advised by Autologic to check and load test power & grounds at gearbox ecu (power latch fault code I think was the reason) ehich proved to be fine.

Hi,
Broke down again Monday, scoped throttle pedal and both Potentiometers are mirroring each other perfectly with no glitches, also watched live data and all good.
Load tested power and grounds at ecu. Removed ecu and have sent to Ecu testing.
Fingers crossed.

Hi,
Had ecu back from ECU Testing after paying £250 for a repair and when fitted back on car it,s the same!
Next step is to scope can and then check actuators .
So still don't know if the ecu is faulty!

Hi, looked into fault code P1795 and it is gearbox counter info:coherence. Number of engagement and disengagements of gears have exceeded 1000000 cycles. So basically it needs new selector actuator.
Spoke to ECU testing and they no nothing of this(how can they fix an ecu and not know?)
Asked them to reset counters for me, to see if we can save buying actuator!
Let you no outcome
