Wont start, gives error code IN 02 on dash

Battery is good. When ignition is turned on, the odometer screen in the dash gives the reading IN 02, and when you turn the key to start the car, nothing happens. No clicks. All electronics seem to work fine when the ignition is turned on.

I had the same problem with my 94 jetta, I would also have the alarm turn on as I connected the battery, if you lower the fuse box being careful not to disconnect anything, there is a box to the upper driver-side aria(that is if you are laying on your back looking up under the dash) this is the alarm control unit, there should be a white label on the wires indicating so (think it says alarm in German) theres a 6 pin(wire) connector and a 10 pin. unplug both connectors and look at the 6 pin connector. There is numbers where the wires are located on the connector, if you take a piece of wire and "bridge" wires 5 and 6 (The largest wires on the connector, red/red w/black stripe) your starter should work, any problem with the alarm system can cause the starter to be disabled. after bridging the wires or simply connecting them do not plug anything back into the alarm box, after this you standard vehicle alarm will be disabled permanently, but you will be able to start your car. If this dose not fix the problem you may have a defective starter, hope this helps.

IN 02 is to indicate its time for a service, its set to mileage interval. If you cant start the car you can try disconnecting the battery for an hour or so. If not it might be a simple as a corroded wire.

Don't know what the code means, but ... 
All electronics seem to work fine when the ignition is turned on. 
Have you tried having anything (lights for example) on while you were starting?  A pretty limp battery will still handle headlights since they draw ~ 8 amps whereas the starter pulls 100-200 amps and will drag a weak battery down real fast. 
Some cars will turn off radio, etc. while starting but the lights should stay on, so I would turn them on, then try starting. If the lights drop a noticeable amount under that condition, then either the battery is weak or the ground cable from it is cruddy at the battery or chassis end.  If the lights do not drop at all when trying to start, then the positive cable that goes to the starter (or starter solenoid) is not contacting at the starter. Most cars use a separate cable stretch for the starter and a different one for all else so it is possible to have everything except the starter working fine but no starter action.
While you are poking around and scratching your head, always(!) disconnect the battery to ground cable first(!) That way if you slip while removing the positive cable and get a wrench between that and any ground point, it won't blow your wrench away.   
If you have cleaned everything and it still won't crank, then either the solenoid is contacting any more or the starter brushes are too worn to reach the commutator.

SOURCE: electronic immobilizer

most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

SOURCE: 97 VW Golf Automatic wont start, battery fully charged

MY guess would be that it's the starter, with an automatic transmission, if the car is not in park or neutral, the car wont even attempt to start, so the clicking sound you say you hear rules that out. Now, im not an "expert" or anything just a guy with some general knowlege, so before you do anything i would recommend having it looked at, but if you feel confident enough, the starter is where i would begin, hope this helps, and good luck.

TOYATO SEQUOIA 2005 TIRE ALARM IN DASH IS BLINKING NEED HELP


Put the key in the ignition - don;t turn it yet. Press the odometer reset button until the total mileage shows (not the trip mileage). Then press and hold the odometer in and turn the ignition on - don't start the car just turn it all the way before it starts. You will see dashes across the odometer and once they are gone turn the ignition off and that will reset it.

2005 lexu 330, turn off maintenance light


1. With your car OFF, place your key in the ignition and turn to "On". Do not start the car.
2. Find the odometer button and press until it reads the total odometer setting, (not the Trip A or Trip B setting).
3. Turn the key to OFF.
4. Place your finger back on the odometer button, press and hold. At the same time, turn the key back to "On".
5. Hold the odometer button in until the MAINT REQD light goes out...should take about 8-10 seconds.

page 77 of the 2004 Lexus rx330 handbook...
(you will find the answer you are looking for in resetting your maintenance light.)
with the odometer reading visible, (not trip A or trip B..) turn off engine.

While keeping Odo/trip button depressed, turn ignition back on (not starting the engine) You will see dashes (instead of numbers) on your odometer disappearing one at a time. it will be replaced by 0's (zeros).. Release the Odo/trip button and your original mileage will come up....
And your done..... until the next oil change.

Thank you for using fixya and good luck

02 rendezvous no crank no start power in dash


Battery may be good but the termanals may need to be clean of corrosion. This means scraping the inside of the cable ends as well as cleaning the posts. Also remove the cable ends that connect to thecables and clean the cable copper and inside of ends. Just because you have dash lights does not mean enough juice is there for the starting. Let me know how it turns out. I hope this helps< The Raz

Flashing light shows a car and a keyh inside


Thank You Very Much for The Maintenance Required Light Info, as far as the flashing car w the key inside. I'm not sure what key we have? When we bought it it only came with one key so we tried to make a duplicate, which ended up not working because we later found out it needs a chip (or probably what I hear as the smart key?) If the light is supposed to be on (and normal) why does it need reset?

The Maint Reqd light blinks after 4,500 miles, and stays ON continuously after 5,000 miles. This is to remind you that you need an oil change. Give the info from you about your key, you do not have a smart key. You have a transponder key. Off topic, but, FYI, a Toyota dealer can program a transponder key for you.
Back to the Maint Reqd light. Here is how you reset it:
Turn the key on.
Make sure that the odometer reads "ODO", and displays the total mileage traveled...If it displays trip a or trip b, push the black button by the odometer to make the display read ODO.
Turn the key off.
Press and HOLD the black trip reset button until advised to release it.
Turn the key ON. (keep holding th reset button down)
Observe the odometer display.
you will see 5 dashes, 4 dashes, 3 dashes, 2 dashes, 11 dash, followed by five zeros, and the total mileage you started with will re-display.
Release the button.
Turn the key off.

Regarding the flashing light with the car & the key: This is the indicator to show potential theives thatyou vehicle has a sophosticated security system, and it CAN NOT be started by "hot-wiring" it. The flashing light is normal, and consumes no battery power. I hope that this helps you understand these two items better. Thanks for choosing FixYA, and the graciousness of a FixYa rating for my solution to you would be greatly appreciated. Glad to be of assistance; please feel free to call upon me anytime. Have a great day.
