    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!
    The green InstallAID™ LED signals a correct installation and shows the status of the module. On new modules this LED is labeled with DATA.

    LED OFF
  • Ignition OFF: CAN bus and module are in low-power standby mode. This is normal.
  • Ignition ON: Either power connection or CAN bus connection is interrupted. Check the two wire taps for power and ground as well as the CAN connectors. Also make sure the CAN polarity is correct.
    LED either dimly lit or flickering erratically
  • A dim or flickering LED is an indicator for interrupted or missing POWER or GROUND connections. The module will get some leakage current from the CAN bus which causes the LED to stay dimly lit or flicker erratically. See previous paragraph about wire taps if applicable!
    LED permanently ON
  • Module is connected to CAN and power, but does not receive the correct data. Recheck all connections thoroughly. A VERY COMMON source of problems is reversed polarity on the CAN wires. Double-check the POLARITY and wire-colors of all connections!
    LED blinks
  • CAN bus is active, the module is connected correctly and ready for use.
  • USE OF THE 3M WIRE TAPS
    This module is installed using the 3M wire taps very popular with 12V aftermarket industry for their reliability and durability. The most common problem during installation is a bad contact between the plugs from the supply wires and the wire taps. Please make absolutely sure that the metal blades of the plugs slide into the slots of the t-taps. It happens that the blade "misses" the slot and the connection looks correct, but doesn't make electrical contact!

    The T-taps come in RED (for thin wires), BLUE (for medium wires) and YELLOW (for thick wires).

    To test if you installed the module correctly after all wires are connected, turn the ignition fully on and watch the green LED on the module. It should blink (flash) to signal a correct installation. If the LED either does not turn on or stays on permanently, there is a bad contact or a missing connection! See detailed explanation of the DATA LED.
    Installation - Steps 1-3
    1. Turn ignition off and pull key before installing! Take driver's side floor mat out.
    2. Lift up the carpet to reveal an aluminum cover. It is held in place by three bolts (1), (2) and (3) which need to be turned 90 degrees each to release. Then take cover out.
    3. Underneath is the confort systems controller unit which is locked in place by two plastic latches (1) and (2). Push both outward to the left while lifting up the left side of the control unit.
    Installation - Steps 4-6
    4. Using combination pliers, attach the two supplied wire taps as shown. The blue tap onto the thick red/yellow wire leading to the rightmost plug and the red one to the green/black wire leading to the small black plug in the middle. Now remove the leftmost plug from the controller by pushing in the locking tab on the bottom while wiggling the plug out.
    5. Connect the remoteKEY wiring harness in between by attaching the original plug to the counterpart on the harness and the other plug from the harness to the leftmost socket on the controller.
    6. Connect both plugs to the wire taps. The red wire to the blue tap on the red/yellow wire and the green wire to the red tap on the green/black wire.
    Installation - Step 7
    7. Connect the remoteKEY module to the wiring harness and secure it in place on a flat surface using the supplied velcro-pad. Now tap the unlock button on the remote once. A blinking green LED on the module indicates a successful installation. Put everything back together in reverse order, then configure the functions of the module according to our Operation and Programming manual. Done.
