This is a two step process, you will be plugging and unplugging the module twice. Please read all directions before beginning.
Prepare the Car: The car must be put into programming mode first. Make sure the car is warm and everything is stable. Turn off accessories and unplug any SD or USB devices. Don’t change any settings or press any buttons while programming.
The car must be in IGNITION position 2 (all cluster leds are ON but the motor is OFF).
Be Patient in this process, wait a minimum of 60 seconds until the audio head has totally booted up. THIS WILL TAKE AT LEAST A FULL MINUTE.
You are ready.
Now plug the module to the OBD2 diagnostic socket under the dash. The COMAND screen will blank and you will see some small white lettering….
There are two programs.
“Step 1: Backup+revert factory” – this program tests the car for coding possibilities and stores the original codings to file, if you were to run it again – it will revert to the factory settings.
Turning the controller will bring you to….
“Step 2: SA628 Activation – this one will activate IHC+ SA628 (the Multibeam) at your car.
Begin Installation: Using the controller, rotate or use << >> buttons to select the first script:
Step1: Backup+revert factory and confirm pressing the controller down or * star button.
This will begin the program…watch the progress bar until you see: “remove the module now” This takes about 1 minute or so. Be Patient, don’t remove module until you see that message on screen. When you do, and only when you do, remove the module.
IMPORTANT: If at the end of this step, you see a message “Exception, see the logfile” – DO NOT RUN STEP 2 !!! Contact us as below.
After completing Step1, plug the Module back in. The screen will again go blank with small white letters-scroll to “Step2:SA628 Activation” and again confirm pressing the controller down or * star button.
The program will install. Observe the progress bar till you again see: “remove the module now” – this takes about 1-3 minutes depending on the car model (sometimes it seems that it freezes at a certain percentage – just wait, it is working). You may see the COMAND screen re-boot, don’t do anything yet, wait.
When the program is finished, you will see the message “Successful SA628 On 1”- then remove the module when instructed on the COMAND screen.
IMPORTANT: Never remove the Module unless the Comand screen tells you to.
You may get an error message in the service screen, for example “Mercedes Connect inoperable” or “Lights are Defective, consult workshop”. You may note the clock has reset to 12:00.
Don’t panic !
Turn the car off, wait a minute, turn it back on, the messages will clear.
TIP: IHC+ (dipped beam) will only work when you:
– select AUTO at the light rotary switch
– push the high beam lever forward and see white high beam with (A) sign at the cluster+blue high beam sign
– the road is narrow (the pavement is single lane every side) and totally dark. Overhead lights (city or brightly lit roads) will keep the system from going into high beam.
– when you are following a car at 30m-50m distance, just shake the steering wheel left-right to make the dipped high beam more visible
