Trip Meter Resetting

[IanRL]

I wonder if anyone can help me with the following query?

The electronic speedometer trip meter in my 2010 Sigma Roadsport SV, re-sets its self every time the ignition is switched off. I’m sure my previous Caterham (with the same type of speedometer) only re-set when the button was pressed & held so I’m thinking there may be a fault somewhere.

The speedometer is working normally & the odometer is recording & maintaining the miles as it should.

Any ideas?

Thanks in advance

First thoughts:

1 Does this type of speedometer have an internal battery? Please add a photo if you're not sure which type it is.

2 Where's the reset button on yours, and could it be making when it shouldn't be? Is it possible to disconnect the button to see if the problem goes away?

...re-sets its self every time the ignition is switched off.

Very odd.   Perhaps ask Caerbont for their thoughts?

Thanks both. Same button does the toggle from odometer to trip so I'm guessing it isn't stuck as it stays on whatever it is set to. Could be some sort of internal battery but it is keeping the odometer reading accurately so not sure.

It is this type of speedometer.

I'll try Caerbont as this sounds to be "unusual" behaviour.

#4  That speedo is definitely the Electronic Programmable type.  I'm not aware it has an internal battery of any sort.
