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 10 -11 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.

3.2.2 LED application

3.2.2.1 High Side Driver LED application

Figure 3.2.2.1A 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 3.2.2.1B 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 3.2.2.1A.

A 1K current limiting resistance is required for the LED. This can be internal or external to the LED device.

3.3 Application Examples

3.3.1 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.


Below is application example showing high side and low side outputs feeding back to further stages of logic using external wiring. The inputs connected to the outputs must be configured appropriately active high or active low inputs using the UIM Project Editor.

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.

B14FF:13 (high side driver 7 short to ground) This DTC sets when the Up Fitter Module detects an open and or current value of less than 10mA on pin 11 – Connector C2 when the circuit is commanded on by an input to the module.


7.0 Appendix

7.1 Appendix A – Definitions USB - Universal Serial Bus- A communication link for personal computer programing of the UIM via the UIM Project Editor. CAN interface - The UIM can be configured to monitor CAN signals in customer programmable logic and perform specialized vehicle functions via CAN. Customer Outputs - The UIM contains dedicated high side and low drivers. The states of the outputs are controlled by the customer programmable logic. Customer Configurable Inputs - The UIM individual switch inputs can be configured as either switch to ground (active low) or switch to power (active high). Diagnostics - The UIM supports Diagnostic Trouble Codes (DTCs) according to the ISO 14229 standard. These DTC’s are defined in section 6 of this manual and also the UIM Project Editor User Manual.
