Is one of those functions throttle position?

I cut and pasted this from a post in may, hope it helps
Press Mode = Dash Part Number - e.g. 1731
Press Mode = Mode Switch Voltage - e.g. BV - - - 5.0
Press Mode = Battery Voltage - e.g. V 11.8
Press Mode = Petrol Sender Voltage - e.g. FUEL 02.6
Press Mode = LPG Sender Voltage - e.g. VL 5.0
Press Mode = Remaining Fuel - e.g. 38L
Press Mode = Instantaneous Fuel (Liters per Hour) - e.g. 12.8 L/H
Press Mode = Engine Coolant Temp - e.g. 63 C
Press Mode = Vehicle Speed - e.g. 45 KM/H
Press Mode = Tachometer - e.g. 2380
Press Mode = Park Lamps Switch - e.g. P OFF
Press Mode = Dash Trouble Codes - e.g. t 00 (Press up/down to scroll through any codes, these are not PCM, ABS, etc codes)
Press Mode = Dash Test - All gauges will move, lights will come on and buzzer will sound.

I am fairly sure T 00 is Timing, but it could be trouble codes, but i have about 6 trouble codes and there is no trouble codes there. and i am pretty sure after talking to my mate who was an apprentice at holden the only way to check error codes is with a TechII or joining terminals 5 and 6 on the OBDII connector under the steering column

Nice thread, I reckon i'll be doing some tinkering about tomorrow lolol

fitz_vt T 00 is a dash diagnostic code it has nothing to do with bcm or pcm codes. ask your mate from holden about the engineering check on the display module (dash)

please note t 00 in engineering mode is a duplicate of
T 03 if using tech 2

basically T 00 - - means fuel gauge sender ok
if T 00 HC means fuel gauge sender open circuit

how do you add a pic as an attachment?
I tried to attach the page from the manual but it didn't work

Ah. that explains alot.
thanks .

display diagnostic trouble codes are..
00 Fuel gauge sender unit – open circuit
01 Fuel gauge sender unit – short circuit
02 Fuel gauge sender unit – intermittent
03 Fuel gauge sender unit – open circuit
04 LPG gauge sender unit – open circuit
05 LPG gauge sender unit – short circuit
06 LPG gauge sender unit – intermittent
08 No serial data from ABS
09 No serial data from BCM
10 No serial data from ECC
11 No serial data from PCM
12 No serial data from SDM
13 No instrument poll from BCM
14 No serial communication
16 ABS fault logged
17 BCM fault logged
18 ECC fault logged
19 PCM fault logged
20 SDM fault logged
24 EE checksum failure
25 ROM checksum failure
26 Internal fault

awesome

Pretty good to find all this out, just a quick question though my VX as far as I know is pretty much stock except extractors. But at idel it reckons its chewing through 3 Litres, anyone got any ideas

People really know how to dig deep for old threads lol.

When at idle it says its using 3 litres to what? per kilometer? or per second?
Dont go by it, its just a rough estimate as to how its running.
For example, I have 250 litres till empty idling at 100kmph. If I put my foot down the 250 will go to 150 based on how I am driving it at that time.

swampy88, instantaneous fuel is litres per hour
