How To Enable & Read Toyota/Lexus Climate Control Diagnostics Codes

How to enable and read the secret climate control diagnostics codes of your Lexus or Toyota vehicles without an OBD scanner or any other tool for that matter.

If the cool air or heat has magically vanished from your Toyota or Lexus cabin, this should be the first step - even before thinking of sticking an OBD II scanner in the port.

The test not only brings out the set, secret codes of the climate control system, it also shows you the overall health of the sensors and actuators and gives you a fair idea of which ones may be sticking or generally, inoperable.

Armed with the codes, you can look up what they mean via: https://throttleholic.com/toyota-clim....

This video (like the rest of my videos on the channel), shows you how, step-by-step.
