“Checking Data” error (1 Viewer)

[EnnK]

So I was gone out of country for a few weeks and when I came back, my 2016 LC would not start. Got the battery recharged and the LC runs fine but I keep getting this error on the screen. It would not go beyond “Checking Data” (see picture)

Also, when I filled up the tank, the pump stopped when it sensed full tank but my gauge shows about 75% full. Not sure if it relates to the problem above.

Help please

Have you tried removing the SD card?

Were you parked inside or outside? I had a similar issue with the gas gauge and it was the old leaky roof/corroded connectors problem.

Id probably replace the battery

I did. Still the same issue

It was in the garage all the time. When you say connector, are you referring to the antenna at the back of the roof?

No, I was talking about the ones behind the kick panels on both sides of the car. I had a similar fuel gauge situation and a gps that wouldn’t load but if you are inside it’s probably not those plugs.

How did you resolve your issue?

The vehicle itself is locking/unlocking with fob, it starts and i even drove it for a few miles. The climate control also works.

It is just the fuel gauge showing 75% full and “checking data” error that i keep getting on the screen (Even while driving) and the inability of GPS to load

The factory battery was replaced today as it was not starting (even though I recharged it and it worked fine last week). So I thought maybe the battery might be issue. So now that I have a new battery in there, the error “Checking Data” or “Unable to read data” is still showing up and Navigation not loading. Any other suggestions would be greatly appreciated.

I did see some sellers selling “OEM” sd cards on Ebay and Amazon. Are these any good? The price difference is huge (think $50 vs $1000 that Toyota quoted for the SD card). Just curious

$50 and the ebay buyer guarantee would be enough for me to try that over a $1000 option. Honestly for $1000 you can get one of those full Tesla 16" Nav systems (which would probably be more enticing if you had a 2008-2011)

Yea almost all of them have return/replacement/exchange within 30 days so that’s why I am sort of leaning towards it. Thanks friend

Do not buy SD card online.
They will not work.

You can obtain from the dealer for sub $200.
Been there done that.
Sorry no link ATM.

Someone posted here with a write up of a website that sold good SD cards though they were a couple years old. $70 I think. I’ll try to dig up the link.

Edit: a couple people had reported using this site: Map Updates - https://toyotamaps.online/map-updates

Card number for reference.
Purchased from local dealership, less than 200.

Was it brand new when you purchased it? I also called Toyota and they quoted a little over $1000 for it. They gave me the item number and when i looked at different Toyota dealers online, the cheapest i saw was $700+ if I ordered online.

The number on the SD card is showing up as $600-1000 but i did call a different toyota dealer and the advisor at this one quoted $210 and a week to get it in.

She said I can go all the way upto 21’ model without fluctuation in price. This is the reference number she gave for those who may want it:

86271-GN8LC-21 (21’ model)
86271-GN8LC-20 (20’ model)
86271-GN8LC-19 (19’ model)

....and so on

Question for you: Were you encountering similar error as mine when you replaced the SD card and did inserting the new one resolve it?

 

[EnnK]

IT WORKED!!!

I disconnected both battery terminals and left them off for about a minute and connected them back on. When I started the vehicle, the map and everything else loaded (from old SD card) and navigation is back on

Glad I tried this before investing in anything else
