I have heard of this, we call it the "gauge dance" or "cluster dance" lol. We had a thread on this on another forum I'm on, here's a synopsis of that conversation (edited for content and language):
Q: Impatient as I am I tried to reset my oil change light like my tundra was and have the truck off and hole the trip reset and put it to the on position. The message display had a lot of letters and numbers and my guages were systematically dancing and all the lights on the dash were blinking randomly. Lack of better thing to do in the situation, I turned the key to off. Just went to key it back on and it was all normal.
What the heck did I do? I apparently didnt do anything harmful, but would love to know what I did.
A: You sent a continuous signal to the PCM by holding the button.
Don't do that.
The guy was trying to reset the oil change light on his Ram the same way as he had on his Tundra, doesn't work the same way hence my response.....:
It's not the same to reset that as on our trucks, turn the key to the "on" position without starting the truck, hit the gas three times and it's supposed to reset the oil change indicator. That's what worked for me anyhoo....
Long story short, the guy found this out by accident, but still interesting. What numbers are you seeing flash? Grantedd I have not tried this myself, so I can't say if it's actually flashing a code, but aside from the normal bulb check, I can interpret the numbers you see on the display.
