Hello,
I need a little help. Over night the temperature dropped. I took my RX out to run some errants- no problems. A few hours after my return my wife went out for a work-meeting. On her way home the following lights light up on the cluster:
ABS, VCS and the parking brake
shortly followed by low-tire pressure.

When she got home I affixed the scanner tool- nothing showed up. I turned the car off and then turned it back on all of the lights were gone. I checked the tire pressure and the rear driver's door was a little low. I filled some air in the tire.

Since yesterday, no lights. But either way I'm a little concerned; can anyone provide some insight. We drive a 2005 RX330

N/B the low tire pressure light also appeared on my IS250

 

Check your battery. These cars do funny things when battery is going bad. My guess.

 

alchemist, I will give this a whirl and report back

 

What kind of temperature extremes are going on there? I know that in Colorado, sometimes in one day, we need a heater on, and then later in the day, the AC! That might explain some variance in tire pressures.

 

Overnight it dropped down to 38, and the snow has arrived

 

Battery test done and battery is fine.

 

Dont worry about it then. If your tires are good. Leave it
