Trip computer playing up

[Micky 4]

Hey everyone my trip computer will cutout when I turn my aircon on and the fuel reading that estimate the kms u have on the tank doesn't read properly rairly and most of the time it give a false reading like for example I have half a tank now and it's reading 150km can anyone help ?

Try this, to fix the A/C issue...

 

 

 

Thanks for this issue mate, made me realise mine has come lose, may explain a few electrical issues I've been having!!

 

Pics are uploading....

 

Its under here

 

 

You will have the EFI comp here rather than the EST one

 

See that dash mounting bolt up to the left? Here

 

The earth should be on that bolt. As you can see, mine is lose, so I'll have to tighten it back down.

 

Should be three or four wires leading into the main connection to go onto the bolt

 

Ignore the black tape on it. Probably factory to cover any exposed wires

 

Don't expect the fuel estimate to be accurate from what I've heard... Mine is trip comp with carby motor and it tends to over estimate massively (example, says I can do 873km on a full tank, every time I fill up). Love to see a carby XF do that on 68L of 91. Bright side is I never get the low fuel warning/beep.

I all ready tightened the earth bold and and I get that beep all the time

It was accurate for about 2 days when I got it

Dunno then mate, you've exhausted my electrical knowledge

My computer went bonkers for a while. Was saying i had 1km until empty when i had a half tank. Then i decided like polsons that i could get 800km from a tank.

I replaced it. Cleaned up some wires behind it. Now it even keeps time!
