PROGRAMMING
RECODING RADIO
1. Turn ignition on. Ensure CODE is displayed on radio display. Enter code numbers using radio station
buttons. For example, use station button No. 1 for code No. 1 and so on.
2. After first number is entered, CODE disappears and number entered is displayed followed by 4 dashes.
After entering 5-digits, confirm correct security code has been entered. If incorrect code has been entered,
entire code must be reentered.
3. Confirm entry of correct security code using "<" (less than) or ">" (more than) buttons. If an incorrect
code is entered, CODE will be displayed on radio display. If security code is entered incorrectly 3 times,
WAIT will be displayed and radio will be disabled for about 10 minutes.
4. If, after 3 more attempts, correct security code has not been entered, radio will be disabled for 60 minutes.
Radio disable time runs down only when radio is turned off.
VERSION CODING
Version coding is performed using a Mercedes-Benz Hand-Held Tester (HHT) and is on-screen menu guided.
After connecting HHT to DLC, vehicle communication is possible as soon as ignition key is inserted into
ignition switch (position of switch does not matter). Version coding menu, position 1, is reached via main menu
and control module adaptation, position 5. There are 2 possible version codings available: readout of version
code and transfer to new control module or readout of version code and to alter code.
To access A/C system version coding, position 2 must be selected and then position 7 for A/C system. Two
selections can be used: A/C system is installed or A/C system is not installed.
SELF-DIAGNOSTICS
RETRIEVING & ERASING DIAGNOSTIC TROUBLE CODES
Retrieving and erasing of Diagnostic Trouble Codes (DTC) must be performed using Mercedes-Benz Hand-
Held Tester (HHT). See HHT instructions for retrieving A/C-heater system related DTC. After noting codes,
see CLIMATE CONTROL DTC
table. To erase DTC, follow HHT instructions.
When retrieving DTC from A/C push button control module, short and open circuits cannot be differentiated
from each other in every instance. When accessing DTC from any control module memory, all stored DTC are
shown. As a result, some DTC shown will not appl
y to climate control system. CAUTION: Before disconnecting battery, obtain 5-digit radio security code from
vehicle owner. Radio will be disabled until properly recoded.
NOTE: Radio will not operate if power supply to radio is interrupted. Obtain 5-digit
radio security code from vehicle owner before disconnecting battery.
