Fuel Inclination meter reset

[xsmatt81]

A. Start car in Ready Mode
B. Go to "Trip A"
C. Power down
D. Make sure your foot is off of the
brake pedal.
E. Push in and hold the
“ODO/TRIP” button.
F. Turn the power switch ON
(push the “POWER” button twice).
G. Turn the “ODO/TRIP” button OFF,
then ON 3 times within 5 seconds.
H. Continue to hold the “ODO/TRIP”
button until the “ODO” indicator in
the display turns off and a 6–digit
code (######) is displayed.
I. Release the“ODO/TRIP” button.
J. Push and hold the “ODO/TRIP”
button for 5 seconds or more
again. The 6–digit code (######)
will then change to a 5–digit
code (#####).
K. After “1” is displayed at the 3rd
digit of the 5–digit code, release
the “ODO/TRIP” button.
L. Approximately 5 seconds after “1”
is displayed at the 3rd digit, the
“TRIP A” indicators are displayed,
and the odometer returns to the
normal operation.[/i]

NOTE:
�� The “TRIP A” mileage will revert to
0.0 miles in this procedure.
�� Do not drive the vehicle before the
reset procedure has been completed.
HINT:
If a write error occurs, start the
procedure again from the beginning.

the 5 digits you see will be

X = first two digits
Y = middle digit
Z = last

X: Values Written Into Meter
(Longitudinal Direction)
Y: Write Status and Result
Z: Values Written Into Meter
(Lateral Direction)
Write Status and Result:
0: Writing
1: Write Completetd
2: Write Error
3: Write Canceled

I think I will try this, my fuel tank is all screwy lately. Temps are normal here..no more then 55 at night..70's during day.

put a little over 9 gallons on last fill up. First pip disappeared at just 65miles with moderate driving with all trips being over 7 miles or so. It's been acting up the last few fill ups. This is new behaviour for the car, for the life of the car it almost always drops the first pip @90-110 miles.

Figure would give this a try if I can find a "level" surface to perform the reset.

mainly I posted this to see what other's experience was with this reset procedure.

Good luck, let me know if you get it to work. I tried for almost an hour a couple years ago and never got the procedure to work....I kept getting hung up b/w step G & H and it would just switch to Trip B and never clear the odometer or go to the reset part.

I did this in a 2001 Prius and could not detect any difference in fueling afterwards. Therefore in my case the tank bladder was probably responsible for the lower refueling capacity.

Wow...that looks super complex. I may give it a whirl in my garage, it's pretty level there. What's the benefit to this procedure?

[Rangerdavid]

+1 yeah, what does this do?

[rigormortis]

all this does is reset the inclination sensor, which is only part of various sensors that are used to sense the level of gasoline in your tank, i think

you left out step a (1)

Connect the connector and install the meter securely in the position shown in the illustration so that it is inclined at a 20 degree angle to the vehicle's vertical line A.

if the inclination sensor is not at a 20 degree angle you are probably doing it wrong or throwing it off

i cannot find any information about specifically adjusting, resetting, calibrating, etc the fuel meter in the combination display.


The fuel level is calculated by the meter ECU in
accordance with the signals of the sender gauge
located in the sub tank and the vehicle speed signal
received from the brake ECU. At this time, corrections
are made by the signals from the inclination sensor
that detect the vehicle's longitudinal and latitudinal
inclinations and the fuel temperature sensors that
detects the temperature in the fuel tank.

I had a go at it last night and was unsuccessful.

I was in a hurry though. Will try again sometime since I am stubborn like that

I am not so certain it will do anything, may just take it into dealer sometime.

I reset mine a couple of months ago. Nothing much changed because, I assume, there was nothing wrong with the calibration in the first place. The ScanGauge has since confirmed that what the gas gauge tells me is approximately in line with the raw reading from the float.

Bear68 posted instructions some time back that were way simpler than this. I'm not sure that it reset the exact sensor this does, but it was a reset for the actual "how many pips = how full the tank is" sort of thing. I remember that he said that the tank needed to be over half full, however.
