3 1.0 INTRODUCTION This guide defines some general electrical/mechanical hardware and software interfaces including UIM Project Editor for the 2018 UPFITTER INTERFACE MODULE (UIM) also known as CAN INTERFACE MODULE (CIM) (depending on market) and is intended to provide specification guidelines. Some key design requirements may be included as a reference. It should be noted that any reference to UIM is interchangeable with CIM, both terms refer to the same module. 1.1 Product Overview The UIM is an electronic control module that has the ability to operate equipment (such as lift buckets, cranes, motors, salt spreaders, snow plows, etc.) with external automotive grade relays via customer programmable logic based on switch inputs and CAN signals. The operation of such equipment is limited to the load parameters of the UIM. The User shall not exceed those load limits. Refer to sections 4, 5, and 6 in this document. The UIM has 11 configurable inputs which can be configured and wired by the customer as either Active Low Input (module output is activated when the module control input circuit has continuity to ground) or Active High Input (module output is activated when the module control input circuit receives power). Inputs are active low only or may be used as a 3-wire digital Hall Sensor Input (dedicated Ground, Input, and Feed). The UIM has 8 high side driver outputs and 7 low side driver outputs. The UIM is connected to the vehicle CAN bus, providing UIM application access to selected signals, and allowing OBD II diagnostic access to the UIM. The UIM is configured using the UIM Project Editor, which is compatible with Windows 7, and Windows 8 Operating Systems. The user must obtain the UIM Project Editor installation package by downloading it from the Ford Website (see vehicle specific owner s guide *see note). The UIM Project Editor allows the user to program the application logic for each UIM output based on UIM inputs and CAN signals. A standard Type B Universal Serial Bus (USB) 2.0 cable is required (not included) to connect the user s PC to the UIM, to download the application logic. WARNING: The UIM can remain powered and operational when the vehicle is asleep if any of the UIM outputs are left in the active state, potentially depleting battery vehicle charge. It is the Upfitter s responsibility to design their UIM application logic, such that it performs to requirements FORD Part Numbers: Ford Part Steering Wheel Location Part Number Upfitter Interface Module Left Hand Drive JK2T-14G589-A* Upfitter Interface Module Right Hand Drive JK2T-14G589-B* Blunt Cut Jumpers x 2 N/A JK2T-14A303-C* Note the second character (*) of the suffix will be dependent on the module version * Note: for Transit please refer to the BEMM (Body and Equipment Mounting Manual) Page 3 of 27 Ford UIM

4 The following items will be required, in order to successfully create and implement a successful Upfitter application: The UIM is pre-installed in the vehicle, or may be purchased separately. Replacement UIM s are available through the dealership. Blunt Cut Jumpers (Two 16-way harnesses). Included as part of the Loose Kit when a vehicle is ordered with a UIM. Replacement harnesses are available through the dealership.

8 3.1.1 Electrical Requirements The user supplied switches must withstand typical battery voltage and up to 32-volt jump start due to possible miswiring. All user supplied switches must be able to withstand a minimum current of 40mA. The switch contact s closed resistance, including vehicle wiring, must be less than 50 Ω. The switch contact s open resistance, including vehicle wiring, must be greater than 100 kω. Either switch type can be wired as an Active Low or Active High. Refer to diagrams below Page 8 of 27 Ford UIM

9 3.2 Outputs External Relay Configuration High Side Driver Relay Configuration For the high side (power side switched) outputs, the user supplied relays shall not require more than 500mA of current to energize the coil. The user supplied relays shall have an operational range of 9V to 16V and with a nominal voltage of 12V.

10 For the low side (ground side switched) outputs, the user supplied relays shall not require more than 320mA of current to energize the coil. The user supplied relays shall have an operational range of 9V to 16V and with a nominal voltage of 12V LED application High Side Driver LED application Figure A High Side Driver Relay driven LED diagram An isolation relay circuit is recommended to avoid LED flickering, as shown above. A 1K current limiting resistance is required for the LED. This can be internal or external to the LED device. Figure B High Side Driver Module driven LED diagram Although the HS drivers can directly drive LED's, it may sometimes result in a low intensity flickering while in the off state, which may be noticeable in low light situations. Above is an LED example circuit which minimizes this flickering. It is the Upfitter s responsibility to evaluate the effectiveness of this circuit in each application. If any flicker is unacceptable, the LED should be driven using a relay in Figure A. A 1K current limiting resistance is required for the LED. This can be internal or external to the LED device.

11 Low Side Driver LED Application Figure A Low Side Driver Relay driven LED diagram An isolation relay circuit is recommended to avoid LED flickering, as shown above. A 1K current limiting resistance is required for the LED. This can be internal or external to the LED device Figure B Low Side Driver Module driven LED diagram Although the LS drivers can directly drive LED's, it may sometimes result in a low intensity flickering while in the off state, which may be noticeable in low light situations. Above is an LED example circuit which minimizes this flickering. It is the Upfitter s responsibility to evaluate the effectiveness of this circuit in each application. If any flicker is unacceptable, the LED should be driven using a relay in Figure A. A 1K current limiting resistance is required for the LED. This can be internal or external to the LED device 3.3 Application Examples Coupling of Logic Blocks Using External Wiring Each row of UIM logic is limited to 3 input variables and two logic functions. In many cases, the Upfitter may need to implement more logic than a single UIM logic row will support. Logic can be increased by looping UIM output pins back to UIM input pins with external wiring. When using this technique, high side outputs must be connected to inputs configured as active high inputs, and low side outputs must be connected to inputs configured as active low inputs.

The inputs connected to the outputs must be configured appropriately active high or active low inputs using the UIM Project Editor.

21 6.0 Trouble Shooting Description of Operation - FET Protection Strategy: The Upfitter Interface Module utilizes a Field Effect Transistor (FET) protective circuit strategy to protect the low and high side driver output circuits. Output loads (current levels) are monitored for excessive current (which is typically caused by a short circuit to ground) and are shut down (turns off the voltage or ground provided by the module) when a fault is detected. A short to battery voltage occurring on either a low or high side driver output circuit may also result in a temporarily loss of operation in the output circuit (no voltage or ground will be applied to the output circuit) to protect the module against a potential over temperature condition. A Field Effect Transistor (FET) is a type of transistor that the module uses to control and monitor current flow on module output circuits. The Field Effect Transistor (FET) protection strategy prevents damage from occurring to the module. Whenever a FET is turned off because of a fault condition a DTC is set in the module which corresponds to the specific fault observed. The module resets the Field Effect Transistor (FET) protection and allows the circuit to function when the fault is corrected or the ignition is cycled off and then back on. The ignition should always be cycled from off to on after a fault is corrected to ensure that FET protection is reset. Module DTC List DTC Description Fault Trigger Condition Module DTCs U1000:00 (solid state driver protection active) This DTC indicates that a FET driver (either low or high side driver) has been temporarily disabled as the result of a fault condition. The FET driver will be disabled until the concern is corrected and this DTC is cleared by a service scan tool. U0140:01 (lost communication with the body control module) loss of communication with the BCM Body Control Module. U3000:49 (internal electronic failure) This DTC sets when the low/high FET driver has been permanently disabled as the result of an ongoing fault condition. Module replacement is required to resolve this fault condition.
