Re: 01 Impala 3.4 Insturment Panel

I had a 2005 Impala. The instrument cluster was replaced due to speedo issues. Mileage was set to the original settings. The lamps are inside. If you get a cluster from a salvage yard the dealer will have to reprogram it. You can do it yourself if you want to.

Has to be re-programmed with BCM in the car. Mileage will not change but will have to be programmed to work with the BCM. Takes 30 minutes.

1. Turn off all accessories. Park the vehicle in bright sunlight to keep the auto headlights off.
2. Turn the key on and off. Remove from the ignition switch.
3. Replace the key and turn to the ON position. DO NOT USE ANY ACCESSORIES AND THE RADIO IS OFF.
4. leave THE KEY ON FOR 30 MINUTES. Do not shut off during this time.
5. When the 30 minute period has passed , turn the key off and remove the key.
6. Replace the key and start the car. All items in the cluster will work.
Lots of luck.
