Default Getting code P1014 LT Connection (GND Short)

Anyone experienced this issue on their RX350/RX350L?

My BlueDriver caught this yesterday. I saw deep in another thread it was the EVAP canister.

Reported fixes:
- Replaced Engine oil (oil looks just replaced)
- Adjusted Engine oil
- Replaced Engine Filter
- Replaced Exhaust Camshaft Position Actuator
- Replaced Engine Variable Valve Timing (VVT) Solenoid

Mines is under warranty so I'll bring to dealer tomorrow.

Default Servo Motor issue on RX???

Hi,
I thought I scan my vehicle given it's still under warranty.

I used bluedriver and it found 2 error codes:
B1449 Air Outlet Damper Control Servo Motor Circuit (Rear)
P1014 LT Connection (GND Short).

Any ideas on the Servo motor issue? I know I heard of these issues on the RC and GS. Lexus/Toyota probably share the parts. Is there a TSB on these for the RX?

Thanks.

Is there a problem with the car? Or are these just transient faults that popped up?

After the dealer fixed the ac amplifier, the LT connection ground short came up. The Servo came before that fixing. If I cleared the code, the Servo comes back over time. LT connection always comes up after some driving.
