    I'm about to take my 2004 in for the 10k service, and I want to ensure that they don't overlook the error codes as they did for my 5k service. However, I don't know if any of the errors are important. Can anyone decipher them for me or point me to a guide to deciphering them? (My apologies if this has been posted before --- a search did not turn up anything.)

    Any information or guidance would be appreciated. I'm getting the following codes and subcodes:

    EMV:
    01-D5 178-48-F
    01-D5 190-48-F
    01-D5 440-57-1
    01-D8 178-2C-1
    01-D8 190-2C-1
    01-DC 178-2F-F
    01-DC 190-69-B
    01-DC 1C6-BA-4
    01-DE 178-48-1

    G/W
    01-DD 110-48-1

    DSP-AMP
    01-DD 190-48-1
    01-E1 110-57-1
    01-E3 -FF-1

    Audio H/U
    63-42
    63-46

    Thanks,
    Paul

    01-D5 190-48-F Registered unit not installed. The was disconnected at ACC (ON)

    01-D5 440-57-1 Registered unit not installed. The was disconnected at ACC (ON)

    01-D8 178-2C-1 No reaction to the connection check. The unit was disconnected after the motor had started.
    01-D8 190-2C-1 No reaction to the connection check. The unit was disconnected after the motor had started.
    01-DC 178-2F-F Trasmission error. The device has given a transmission error.
    01-DC 190-69-B Trasmission error. The device has given a transmission error.

    01-DC 1C6-BA-4 Trasmission error. The device has given a transmission error.

    01-DE 178-48-1 Slave Reset. This code is given when a slave device is disconnected after the motor has started.

    G/W Gateway ECU Physical address 1C6
    01-DD 110-48-1 Error DD not listed in my documentation! Probably Master Reset (see below)

    DSP-AMP Amplifier Physical address 440
    01-DD 190-48-1 Master Reset. The main system was disconnected after the start key in On (Ready) was selected.
    01-E1 110-57-1 Voice recognition device ON error. The AMP device registered that the amp output does not work even when the output device is active.
    01-E3 -FF-1 Registration request transmission. The command for registration request was given by the slave device or the registration request command was given on reception of the connection confirmation submaster. NOTE: Possably the DCT is not directly the problem (Unclear in German text!)

    Audio H/U Physical address 190 Radio Tuner unit (Code 63 is CD Changer)
    63-42 CD can not be read
    63-46 CD is scratched or dirty or inserted upside down


    Sounds like you may have a loose connector or have been playing with the power to the system ?

    I had some codes too when I found the diagnostic mode. Could have been from when I added my EV mod. Cleared them, none came back.

    If you were working on something in the car, such as EV mod, and had the car on while working on something, that would explain the codes.

    Since you recorded all the codes, try clearing it and see if any come back. If they never do, then it was some sort of fluke.

    Thanks for the help! I haven't done any mods or played with the power system, and about four of the codes are new in the last month (I first wrote them down about a month ago), although I remember some from when I first checked months ago. I'll push the dealer to check them and resolve the issue.

    Is there any method of determining what unit is giving the problems? Are any of these likely to be safety related? Or reduce MPG?

    Nope. They pertain to the NAV, radio and MFD mostly. There is some communication beyond that to the other networks, but for informational purposes only.
    I.E. so the MFD can give you the hybrid status, and that a scan tool hooked up to the DLC can possibly read codes.

    You find the codes in the service manuals. It would appear that not all the codes generated are in the manual for each year.
