body error codes
Hi i am new here, I just bought a 2002 rx300 and recently I am having problems with the climate control, doors and the dash. I scaned it with my obd reader and it generated body code errors B1211,B1212,B1216,B1217,B1241,B1261 etc.
has anyone experienced this and found solutions. most of the errors says ECU communication. right now it runs but there is no air coming out of the vents and the screen for the climate control is blank.

Arm yourself with circuit diagram and start probing for voltage on the communicating modules. Having a scope helps as you can determine if there is communication actually happening. I suspect a voltage issue ... You can also start by checking fuses. The circuit diagram will pin point which ones to check.

Thanks. I will check fuses later. Right now i have to disconnect the battery cause the parking light wont turn off. I think cause it does not know if the doors were locked cause it wont work.

Take the lights out of Auto.
There may be software gremlins, and they will clear out by removing battery for about 20 minutes.
Remember to wait 2 minutes after turning the key to off, before removing the battery terminal.
