Pessoal,
achei essa informação, gostaria de compartilhar. No meu caso funcionou.
Serve para acessar as informações "escondidas" no computador de bordo, tais como velocidade real, pressão de combustível e várias outras listadas abaixo... Se alguém quiser tradução é só falar. Achei um vídeo tb explicando como faz se não entender a sequência abaixo. http://www.youtube.com/watch?v=9oSdk8WGTKw
Instructions for accessing the 'secret' menu options:
1. Hold down the 'day trip reset button' (I think??)
2. Insert key fob into slot (puts car in standby mode??)
3. Repeatedly press the reset button until you reach menu option 19 (Lock/Unlock)
4. Wait a moment for the option to be selected
5. Add the last 5 or 6 digits from you VIN (maybe chassis # ?)and enter that sum by repeatedly pressing the reset button (more on this later)
6. Additional options should be accessible until key fob is removed
A note about point #5: This caused confusion and was clarified later in the original thread, so I will give an example:
-The last five digits of the VIN are for example '63081' 6+3+0+8+1=18. -Therefore you will need to press the button 18 times in quick succession and then wait a moment for the value to be accepted.
Now if this works as described the following options will be available (Note: each option may have several sub-options):
1. VIN (?) or chassis number
2. Test 'combination display' (instrument panel or multi function disp? not sure)
3. Unused
4. Fuel usage, current (MPG ect.)
5. Fuel usage, average (range?)
6. Fuel level (left tank, right tank, total ect.)
7. Real time data (coolant temp, exterior temp, RPM, speed)
8. Speed data (actual speed, displayed speed, various avg speeds)
9. Current voltage
10. Distance/week (?? not sure on this one)
11. Units used in display (kilometers/miles, liters/gallons perhaps?)
12. Speed on arrival???? (don't ask, I have no idea)
13. test sounds for the 'comb. disp'(warning chimes ect)
14. Error code log
15. Ports ?
16. ? Unknown, though one of the entries apparently displays/ controls the value for the adaptive headlights
17. ? Unknown but may display heater info
18. Test warnings on 'comb. disp'
19. Lock on/off (as discussed above, this is where you get access to all these menus.)
20. Corrections?? (not sure)
21. Reset 'Combination Display'
