1604 Code (1 Viewer)

I'm new to the 200 series (I'm used to old technology 80 series). I recently had the "maintenance needed" warning light come on. I went to the local auto part place and had them run the code for it and it came up 1604. From what I have read on other Toyota forums this is a common code and can sometimes mean nothing. Anyone else have any experience with this code? It seem to be running fine. I haven't driven it for awhile so I also had the battery checked while I was there. They said that it needed a charge(done). If it is corrected will the code automatically reset itself or do I need to go to the stealership to have them reset?

Try doing a hard reset.

Disconnect the battery for 10-15 min, then reconnect and start it up. See if the code comes back. Sometimes that'll clear up a code permanently.

The OBDII reader at the parts store can reset the light. If the issue is not resolved the DTC will come back...

Shoot me pm with your email address. I will send PDF files with trouble shooting procedure. There are four parts to this code and it is P1604.

Tried both the battery disconnect and the scan tool. Neither would reset the code.
