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.
:dizzy: 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?
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.
if it ain't broke, don't try and fix it for the sake of tinkering. the inclination sensors correct for the car being on an incline when calculating what to display on the fuel gauge. you could throw off their calibration if you're not on a level surface when you do it. they recommend doing this on an alignment rack...
At one point over the summer I parked on a fairly steep slope to the right, leaving the system powered on, to take a quick stop into a store. A little while later I noticed that the MFD average had reset itself. Apparently the strong tilt had been interpreted as a refueling event. . I also went over some washboard sand roads over the summer that were bouncing the whole instrument binnacle up and down so hard I can't imagine how the sensors would be able to hold on to any concept of reality under that kind of punishment. . I've never reset my sensors since the gauge and the sender seem pretty well matched, but I might play one of these days. . _H*
In my case I thought that the gauge might have been off its calibration since my standard "fill" is maybe 7 gallons, less if it's cold. It would have been nice to find that there was an extra usable gallon or two sloshing around in there, but unfortunately that isn't the case. Instead I just run it down a bit farther since I have the ScanGauge giving me enough resolution to be comfortable.
meh. this must be for older models like 2004. don't work. Unless Iam just not getting it. I think I will leave it alone
