VT-VX Hidden Trip Computer

[djlingard04]

Can any one tell me what all the items are in the hidden features are all about. To get them to come up you just hold up and mode while you turn the key on then press mode to flick through them. Some of them are litres in tank, litres per hour and digital speedo and tacho, battery voltage but I do not know what the others are. Rang holden and asked them and they would not tell me must be something good.

[t-rev]

there is a guide on how to do this straight from this site but it doesnt appear to work...
Special Functions on VT trip computer

Hold down the mode and up buttons with the ignition off then start the car and release them a few seconds later, it gives you digital batt voltage, speedo, tacho, temp fuel consumption, fuel left in tank and other cool stuff.

sorry i just tried it again and it does work but now i dont appear to have my km's left in tank and a couple of other things aswell

[Pedroman]

Yeah I hers thats how ya do it but I've tryed on mine with no results either.

[t-rev]

what you do is only hold the up botton and the mode botton, NOT both!
i havent taken it for a drive yet though to test it out

[Pedroman]

Good call there T-rev, I just went down stairs to try it and it works!!! when you hold the up button and the mode button together, not the down button. and start the car..........hehe cool

[djlingard04]

I know how to do it but what is all the other crap in there????

[daz08]

I gave it ago aswell....can u get to keep sum 2gether.. like i want the digital speedo but with the dte n trip aswell

There's an article on autospeed that tells you what a number of the functions are, but unfortunately some still remain a mystery. One cool one is the actual engine temperature - handy to see how she warms up on those winter mornings.
the article is at:
http://autospeed.drive.com.au/cms/article.html?&A=1951
or
www.autospeed.com/A_1951/article.html

or just google it.

hey mitch01,
you have to purchace something in order to read the article!!!!

[mitch01]

Arghh it worked for me before.
If you want to see it the best way is to do a google search like "autospeed vx hidden data" then click on the link and you will see the entire article without a subscription. you can do the same thing to see any article as long as you use right click and 'open link in new window' to open each one seperately.
its a good loophole cause there's some good articles on car tests and stuff particularly if you're into imports (which is probably unlikely at this site haha)

[t-rev]

yeah i googled it and it worked
the only annoying thing with the hidden features is that they dont stay on after you turn off the car which is kinda stupid!

VT/VX Hidden Data

A string of useful data is hidden in the Holden VT/VX trip computer display...

Do you own a VT or VX series Holden? Do you have a thirst for information? If the answer is "yes" then take a look at the 'hidden' displays in the factory trip computer...

Depending on the spec of your VT/VX Holden, a single window or triple window trip computer will be installed. The basic single window computer offers an odometer, trip meter, distance to empty, service reminder and an overspeed alert. Upmarket three window models add average road speed, average fuel consumption, fuel used, instantaneous fuel consumption and trip time.

The Holden owner's handbook instructs those who are "technically minded" how to customise the trip computer display to your personal preferences. However, beyond this are some 'hidden' displays that are not printed in the handbook or even in Holden's service manuals...

Let's take a look at how to find these hidden goodies!

To gain access to the hidden displays you need to hold down the trip computer's Mode and Up buttons while the ignition is switched off. Then simply start the car and release the buttons and you've found 'em!

There are several displays that can be scrolled through by repeatedly pressing the Mode button.

The hidden display for coolant temperature is particularly useful. Ever wondered what the actual coolant temp is when the needle moves off zero or is halfway? Simply start the car from cold and watch the relationship between the coolant needle and the numerical display. The engine should warm up to around 90 degrees Celsius.

When the letter F appears with a number alongside you know you're looking at the precise number of litres of fuel remaining in the tank. There is also another F display with a l/hr appendage - this is the instantaneous fuel consumption. At idle, fuel consumption should be in the vicinity of 1.5 litres per hour.

The display seen here is for battery voltage. There should be around 14-volts being shown with the engine running. The display that follows should show 5.0-volts; we believe this is related to the instrument cluster.

The 'all on' display is useful for general faultfinding. This function sends the speedo needle to 100 km/h, the tacho needle to 3000 rpm, illuminates all of the warning lights and display segments and sounds the overspeed buzzer. What good is this, you ask? Well - as an example - it would let you determine whether you have a blown oil pressure bulb.

There are also some less useful displays that are accessible, such as numerical road speed, numerical engine revs (which is difficult to read due a very fast update rate, as seen here) and a VIN display.

Unfortunately, there remain a few displays that we haven't been able to decipher. One shows the letters PN followed by a number, while another shows the letter t followed by 00. There is also a display that contains the letters vP followed by a constantly changing number; we have no idea what that means.

Finally, the display that reads P OFF presumably isn't telling you 'where to go', but indicates that the "police mode" is not activated. We're told only a TEC2 tool can access this mode and its function is unknown.

So there you go Holden VT/VX owners - your trip computer display is home to an array of displays you never knew you had. Now get out into the garage and try them for yourself!

I read this article too and it's lame. P OFF does not mean police mode. P OFF means your parking lights are off. Go to that section yourself and see what happens when you turn your parking lights on and off. Police mode can be enabled with the Tech2 and all it does is change the speed alert function to a digital speedo.

Ciao ...

Does any one know what these other funstions are?

thanks for the article i like the accurate temp reading makes me less paranoid cheers

I have an XU6 with level 3 cluster and in the top right of the 3rd window it has PSI, is this a boost guage or something else? How do I access it?

[vk6hgr]

while another shows the letter t followed by 00.

According to Mr Gregories manual, that's the dash module diagnostic code. 00 means no logged errors. :-)

theres another thing i found by accident the other day while i was about to fill up with petrol. if u hold the up and down buttons down the turn the engine off then release the buttons after a few seconds there is a distance to arrival and time to arrival display where u can enter how many kms or how many mins/hours til u get to ur destination. i have a 3 window cluster i dont know if it works with the single ones

[VXII_S_smokin]

it takes the mind of a child to work somethings out. the article wondered what PN stands for. my 11 year old sister figured it out, it is PIN as in the 4 digit PIN for the standard stereo.

[BUNDYSS]

Thanx guys, very cool stuff. I have a single cluster and just tried the up/down then off and didn't work. Just wish it was on all the time

[TigerVX]

According to Mr Gregories manual, that's the dash module diagnostic code. 00 means no logged errors. :-)

If you use the up and down buttons these numbers to the right of the tcount up and down. I don't know what the purpose is though.

[VTPREDATOR]

Police mode can be enabled with the Tech2 and all it does is change the speed alert function to a digital speedo.

Ciao ...

i beg to differ, caus i have both

[VTSSDUDE]

Another cool thing is purchsing one of those PCM Scanners. Like around $400. They they you the temperature, oil pressure, revs, etc all on the one screen, all in digital.

How did you get the digital speedo to stay there and not disapear when you turn the ginition off?
