Hi there, anyone able to tell me what error code C1772 is for, the code reader says
1. Air suspension
1.1 navigation module

No check light or anything coming up on the dashboard.

Or does anyone know where to get a list of Lexus error code from.

Thanks

"C1772Air Suspension Vent Solenoid Output Circuit Short To Battery" would be the most logical one
Can You clear the error codes logged in the modules , drive a week and recheck i they come back ?
I am most used to troubleshoot bmw electronics , and we have to note all error codes , reset all and drive and test again ,,
So many false positives....

Or You can download "Toyota Techstream" and buy a cable on ebay , (or cable and software included) then use your laptop
should give You more accurate information,

HI there, thanks for your reply, yes I got the Toyota techstream software and cable, it was a false positive because I don't even have air suspension in the 450 h.

Now I would like someone to walk me through on how to make some changes that usually only the dealer can change as follows.

I would like to have all doors unlock when the car is put into park, as at the moment only unlocks when the driver's door is opened.

Also to have the headlights turn off when I turn the ignition off as at the moment they stay on when I turn ignition off and will only turn off when I open the driver's door!

This can be done in Techstream.

Also to have the headlights turn off when I turn the ignition off as at the moment they stay on when I turn ignition off and will only turn off when I open the driver's door!

My headlights stay on all the time unless it is on auto, regardless if I open or close the door after ignition is turned off.
