Tomyspeedy Posted December 16, 2015 Share Posted December 16, 2015 In aid of helping others with any Air conditioning faults I thought i'd take the time to make a post about the inbuilt diagnostic codes for the air conditioning. How to diagnose air-con not working on a Toyota Supra. Faulty air con? Get the diagnostic codes out of your Supra using the following method. With the ignition switched off, hold down the two larger heater control buttons (Recirc and Auto buttons) , then switch the ignition on. . Any fault codes stored in the system will then flash the LEDs. See below for a link to the website with the fault diagnosis codes: http://www.jack-frost.co.uk/toyota_supra_air_con.html After being unable to find a stickied guide I thought it best to provide a link for others.
