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..

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.
