Today while driving, i got the red "!" and "TPMS light" ON, with the LCD reading "check system".
This is different from the "low tire" readout which comes on when the tires are actually at low pressure. The error i am getting is something else according to the manual. It states if i get this code, to go to the dealer. That doesn't help me!
Here's what i think happened...
I've been working on a couple gauge cluster projects, so i've been switching between my factory cluster and a spare.
For the past 3 weeks or so, i've had the spare cluster in. Everything has been working fine. Then the other day for some reason, i thought the "TPMS SET" button under the steering column was the "AFS OFF" button, and i pressed it and it didn't turn ON or OFF the AFS (duhh...) so i kept pressing it and holding it down and everything, because at that time i really thought it was the AFS button and i thought it could be broken... Then i realized it was the wrong button
But everything seemed to be OK...
Well, it's been a few days, and today i switched back to my factory cluster. After 20mins of driving, the TPMS light came on in the dash and read "check system".
I thought it had something to do with me switching the clusters, so i switched to my spare again. After 20mins of driving, i didn't get the error code!
So i switched back to my factory cluster again. After 20mins, the error lights came back on...
I tried unplugging the car's battery for a half hour, but no such luck. After 20mins of driving, my factory cluster still reads the error code.
So what the heck could be wrong?? I didn't do anything to the clusters that involve and electrical, so i don't think i damaged anything.
When i accidentally played around with the TPMS SET button the other day, i had the spare cluster in. And i didn't get any error codes. But when i plugged in my factory cluster today, i get the error lights.
What do you think could be wrong? Is there something else i can try to reset the factory cluster? Do you think the TPMS memory and ecu is in the cluster?
