This module comes with our USB Field Upgrade and
Configuration Port! We recommend connecting it to a
computer BEFORE YOU INSTALL and using our support app
"m4cconnect" to do a quick firmware update check.
M4cconnect as well as all other information regarding USB
update and configuration can be found at
www.mods4cars.com/usb. You can even configure and
activate your favorite module functions and settings on screen
before the module is installed in the car! It is a good idea to
permanently install the USB cable with the module in the car,
leaving the computer plug in an easily accessible spot for later
use with a Wifi/3G/4G connected laptop.

IMPORTANT
TROUBLESHOOTING TIPS
If the top does not work properly or at all after installing the
module, these tips can be very helpful:
• 1) Turn Function 1 (Main Switch) off (Setting 0). The
module will be completely passive. If the problem still persists
and the top won't work, check all connections. Please also
check the green DATA LED on the module!
• 2) Function 2 now has a valet mode (Setting 2) on many
modules. Valet mode completely disables opening of the top.
Check the setting for function 2 and make sure the module is
NOT in valet mode!
IMPORTANT: Not all modules have the valet mode! Please
check the Operation and Programming Manual!
FUNCTION OF THE DATA LED
The DATA LED shows the module status and helps
troubleshooting issues during installation:
• When the ignition is ON: The LED should BLINK (flash) in
a regular pattern (about 1x per second). This indicates that the
module is receiving data and should work OK.
• When the ignition is OFF: The LED should BLINK (flash)
as long as the data bus is still active and turn off after a while
(max 5 min) indicating that the car has entered stand-by
(sleep) mode.
• If the LED is permanently lit with the ignition ON, the
module is NOT receiving data from the top controller and all
connectors should be checked.
• If the LED does NOT light up at all when turning the
ignition ON, the module is either not getting power or not
receiving ANY data. All connectors should be checked.

Installation - Steps 1-3
1. Open the convertible top for better access. IMPORTANT:
Turn off ignition and pull key out before continuing! Open
the cover behind the driver's seat (left side of the car) as
shown. Use a flat screw driver or any flat object like a coin to
pry it out on the top.
2. Lift up the padding to reveal the convertibe top controller.
The bottom plug (marked with the arrow) will have to be
removed in the next step.
3. For better visualization the locking mechanism is shown on
the smartTOP plug (1), marked with an arrow. It needs to be
pushed down while pulling hard on the plug. Once the plug is
out, plug it into the matching socket on the smartTOP wiring
harness (2).
