No read out as far as what gear I'm in or read outs including mileage, trip odometer or anything else, tire pressure etc. could it be light bulb?

Odometer
The odometer is an electronic digital display. Digits displayed are illuminated by the odometer backlight bulb. The odometer backlight bulb brightness is controlled by class 2 messages from the BCM to adjust the display for daylight and instrument panel dimming operation. The trip odometer and total odometer will show in this display area. The push button in the lower right side of the speedometer is used to toggle between the trip and total odometer readings. To reset the trip odometer, push and hold the button down for at least two seconds. The total odometer display has six digits with no decimal display. The trip odometer has four digits including a decimal point and indicates tenths of a mile or kilometer.
The body control module (BCM) stores the vehicle mileage. If the BCM fails, the cluster will display the last valid mileage that was sent before the BCM failed. For replacement of the BCM refer to the BCM section of this service manual. Replacement instrument clusters do not require odometer pre-setting before installation. If the instrument cluster is replaced, the mileage stored in the BCM will be sent to the new cluster via serial data, and shown in the odometer display.

Your best bet , take it to a qualified repair shop.

Did you try disconnect batery for 5min.

It means your car needs an oil change, based on mileage. If you take your car to get the oil changed, they can reset the light for you. If you want the light off now, try holding in the odometer reset button, with the key on but engine off, until little dashes appear then one by one dissapear. This procedure may need to be done either on the odometer total mileage or trip A mileage or trip B mileage.

Step 1: Have car off.

Step 2: Push and hold in trip reset button.

Step 3: While still holding button in, turn key to ON, but engine off. Wait for the little dashes to appear and disapear. If it doesn't work on the odometer setting. before turning key off, switch to Trip A setting. If the procedure doesn't work on the odometer setting or Trip A, try Trip B setting.

Step 4: Turn key off. Then start car. Maint. required light should be off.

Hello: Check tire pressure, Proper pressure should be on a label on the driver door and door frame. If tires are low, air them up to spec's. If only one tire is low you should check it for a puncture.

Identify that it is indeed the maintenance light that is on.

With the car off, insert key into the ignition and turn the key to the on position without starting the vehicle.

Change to odometer so it reads the total miles and not the trip mileage. See the blue arrow in photo for the location of the button to change odometer from trip mileage to total mileage.

Hold the reset button until the maintenance light goes out.

If you want to reset the light/message:

Close all the doors, booth, hood etc. hatches,

1. Make sure you have Trip odometer 1 (T1) selected.
2. Turn the ignition key to 'I'-position.
3. Press the trip odometer reset - keep it down.
4. Turn the key to 'II'.
5. Wait till the service light blinks a few times or you hear a 'beep'.
6.Release the trip odometer reset.
7. Turn the key back to '0' - service light is reset.

If this doesn't work, try:
a) 2. before 3. then continue as above
b) 5. Wait until the previous mileage appears again to the trip odometer.
c) 7. before 6.

You can reset the service counter at any time. Do not forget to service your car!

IF YOUR SPEEDO IS WORKING THEN YOUR VSS IS OKAY, BAD VSS WILL STOP SPEEDO AND USALLY CAUSE HARD SHIFTING. NORMALLY ODO IS CONTROLLED BY SERVO MOTOR WHICH MAY HAVE WENT OUT. CHECK EBAY FOR REPAIR SERVICES OR SIMPLY GET A SALVAGE CLUSTER AND HAVE MILEAGE RESET

I get many calls a week for this procedure...
This is really easy! Follow these directions:

Turn the key ON

Look at the odometer, and verify that it displays "ODO" and the total mileage traveled. If it is on "Trip A" or "Trip B", press the black stick next to the odometer to read "ODO", and the total miles traveled.

Turn the key OFF.

Press in, and HOLD the black trip meter reset button, hold it in.
DO not release it.

Turn the key ON, do not start the engine

Observe the Odometer display. The total mileage traveled will disappear, and you will see 5 dashes, then 4, then 3, then 2, then 1 dash, and finally, 5 zeros. Then, the total mileage traveled will redisplay.

Release the black trip meter reset stick.

This completes the reset procedure, and it will be back on in 5,000 miles, to remind you of you next oil change.

Hope this helps!
