Guys,
I have the following diagnostic codes on my AC system when I run the onboard diagnostic program:

EB1227
EB1231
EB1234
EB1416
EB1422
EB1424


Decoded:
1. Outside Tem indicator temp sensor(014)
2. ETC sensor(B11/4)
3. ETC sensor(B32 ? or B12)
4. Coolant Circulation pump(P.113 ?)
5.Series Interface(K1) connection to instrument cluster((A1)
6. Activated charcoal filter actuator(A32m2) open.

I am not sure if these are current or have been there a while.
Is there a way to clear these and see if they come back?

How should I proceed?

Is this for a 2000 E320 ? you have one confused controller. Has it ever been replaced or is it the original one ?

Clear the codes and run the test again. After all codes are read press both the auto buttons to clear. Then do the test again.

Its the original controller but I had all errors cleared on it through an SDS system a couple of years ago.
I think my DTC must be permanent because I could no clear them using the directions that Kajtek1 kindly sent. It may be an operator error.

Its an E320 MY2000

Error codes can only be erased after each of them has been gone through. Use the right Auto button to go through every code. When the screen shows E FF, you need to press both AUTO buttons. This will clear the code. After that turn the ignition off and Then do the test again and post the codes that come up.

For 2000 E320, the information for the Outside temperature and the engine coolant temperature comes from the instrument panel over the K1 signaling line. If the K1 line has a problem (which the fault codes indicate), the ETC and outside temp information is likely not available, and the controller uses the last known values.

Try posting the sensor values from 1 to 43, which would show the sensor values, as well as configuration of the controller (version coding).

Other errors like the aux coolant pump, and smog actuator motor could be hard electrical failures which should be addressed separately.

MrBoca, there is the last column on the document in the link labeled Test step/Remedy --what is the referring to? I guess its a section in the full manual.

If you click on the square next to the sections, it will bring you to how to do the troubleshoot / remedy.

I reference sections like this, so smart people like you, can do the troubleshooting more in depth.
