Toyota Battery Replace- You Need to Know This

[VaTom]

Replacing the battery on my son’s 2002 Toyota Camry this morning. Great car with only 80,000 miles. Took out old battery and went to Advance Auto and got a new one. Had the battery out for about two hours as I had to clean up cable connectors, etc. Put in new battery car started and ran fine but would not idle. RPMs would drop and engine would shut off instead of idle What the heck? Had me stumped. Went on Google and found a video. The ECU had to reset and “relearn” the proper idle rpms. Here is how it is done.
1. Turn off all electrical accessories.
2. Put in park and turn the key on and off three times.
3. Put on parking brake, start car, rev to idle rpms and with foot on brake put in drive. Return to park.
4. In 4 minutes of idling the ECU relearned the proper idle rpm setting from factory and all ok. Drove around neighborhood and car was fine.

Thanks to the guy who made the video on you tube!!!

You must have left the battery out too long. I've been a Toyota owner since 1976, and have three sitting in the carport right now ('11 Tacoma, '18 Rav4, '99 Avalon). We've had three Camry's ('86, '96, '97), two Corollas ('11, '12) and a Sienna ('06). I've never had to reset the ECU after a battery replacement on any of them over the years since they had an ECU (my '76 Land Cruiser didn't have one).

I usually have the new battery connected within 5-10 minutes of removing the old one. The only thing that needs resetting usually is the clock and radio stations.

Yes-The old battery (Interstate Brand) had a vapor leak in the casing around the positive terminal.The casing had actually pull away from the post a bit. Battery still started car but it alot of battery corrosion gunk on the cable end. I wanted to take the old core to Advance when I bought the new one so I didn’t make a return trip. I had to neutralize the gunk and clean up the copper positive cable connector with wire brush. Took some time as it was caked on the copper.
