Weird Electronics Behavior?

[Andres G]

I have a 2013 LC200. Since I got it about 9 months ago, I have noticed some strange behavior with a couple electronic features... specifically two things caught my eye:

# HVAC - Randomly, I will notice it is turned completely off when I get in the truck in the morning. I always run it in the AUTO setting, so I see no reason for it to be any different when I turn on the truck in the morning vs. when I s*** it down at night. This doesn’t happen regularly, bur rather very infrequently (maybe two or three times since I got it), and I can’t pinpoint the cause.

# Parking Sensors - Again randomly, these will beep to let me know proximity to an obstacle in the front of the car when I am parking (office parking lot), but occasionally they stay completely quiet. When reversing however, they work all the time. On this I wonder if I turn them off when running thru the car wash, and then forget to turn them on again? Does anyone known if these reset when the truck is turned off (meaning if they go back to default)?

Thoughts?

Check your front floorboards for moisture. If you don’t find any, pull the carpet edge trim to roll carpet back some and look deeper.

When the windshields on these leak (or the sunroof for that matter) which happens often enough after sub-par work, the water gets into the body harness connectors at the base of the A-pillars and all kinds of odd electrical stuff ensues.

If there is water you’ll obviously need to address the leak, but most likely also need to get in to those connectors and clean the corrosion out of the terminals.

I also have a 2013 LC200 which I've had since new in 2012. To your points:

- When set in AUTO and left in AUTO at shut down, it should return to AUTO when the car is re-started. I would check to make sure your recirc door above the cabin air filter is not broken and functioning properly. To do this, open the glove box, remove the examination plate at the front of the glove box so you can see the air filter/recirc door. Then turn the ignition ON (two presses of the Srart/Stop button with your foot off the brake) and repeatedly press the RECIRC button below the NAV screen to see if the door/flap above the cabin air filter opens/closes as it should. If not, then you need to fix it.

- The Parking sensors do not reset when the vehicle is shut down. If you turn them OFF, they stay OFF until you turn them back on again. Conversely, if you turn them ON, they stay ON until you turn them OFF. Also, note that obtacles to the front are only detected if they are to the sides of the front bumper - wher the sensors are. A narrow obtacle, like a bollard often found in parking lots, will not trip the sensors if it is directly to the front of the vehicle. Sensors in the rear, however, are at the sides and on the face of the rear bumper, so obstacles will trip the rear sensors whether they are to the sides or directly behind the vehicle.

I am re-surfacing this thread, today I experienced something very weird with my climate control

It turns out, I am unable to turn off the air conditioner. The button on the bottom left corner of the climate control screen would indicate that pressing there should turn off the AC compressor, but to no avail, it just will not turn off.

Anybody have any idea what could be going on here?

@Andres G: Is your center console cooler box on? You can’t turn off A/C when it’s engaged.

*Edit: I see you're from Argentina. I don't know what trim level you may have or if you have a cool box.

Good call. Yes the cooler box is on! I’ll give it a try with it off.

Thanks!
