Technical Panda fault codes

[Murv73]

Hi all, hoping somebody might be able to help me.
I have a Panda 1.1 ecodrive 2009
It runs perfectly around town but on the motorway it seems to lose power and I have to sometimes drop to 4th gear to get up hills.
It starts on the button and idles perfectly, no fault lights on the dash but a friend's OBD reader is showing the following codes:

U1602 pd
U1600

Anybody have any idea where to start please?
Thanks in advance,
Chris



I've tried Googling the codes but having no luck,

Hi,

Those are for the CanBus network

The cars internal "comm's"

Unlikely to truly effect running

Tell us more about the Panda,

Mileage, time owned

Work done, basic service history

Age of battery and Black Earth Cable..

 

[varesecrazy]

We had Great service from an early 1.1,

A common failing in later 1.1's appears to be poor wiring to the CoilPacks

BUT. that is conventionally a starting and low Rpm issue

@varesecrazy is Correct

U1600 and U1602 nothing to do with you running issue

Usually just a glitch

Often associated with a low battery

CUSTOMER'S REPORTED FAULT​

a) The car fails to start and various warning lights come on (code/E.S.) on the instrument panel.

b) Engine rotates but does not start.

TECHNICAL CAUSE​

1) Engine fails to start. Power windows, central door locking and fuel level gauge occasionally do not work regardless of whether the engine is cold or hot.

2) When an Examiner diagnosis is performed on the control units, the following messages are displayed (even individually):

• NCM: u1600 electronic key signal is not plausible.
• Body computer: no error.
• ABS: c1108 serial line, invalid signal, intermittent.

3) Disconnect and reconnect the battery: the car starts and runs correctly, even for long periods of time.

OPERATION​

1) check for errors in the control units.

2) Check the body computer software.

3) check the conditions of the battery.

4) Report the case to Te.Se.O. and attach any surveys as instructed above.

sorry to dig up this post, but i'm facing something similar!

fiat panda axa1a 169, for the last few months have had the engine light on and went to the mechanic, one gave me a report with the codes P0606 and U1602, it has taken a new battery since this, but the light is still on and it still as those symptons of shutting down while riding and turning back on, mostly on low rotations

Hi folks, came accross this forum just today while googling some of my headaches This is my family's Panda, has about 298k on it since 2003 but only about 7k on our hands, we got it around 2018/2019, after the previously owned '98 Corolla went to the junkyard after someone running a stop sign...
