  2. Scan Procedures for Ford EEC-V OBD II Systems

  3. User Inputs and Display Display The user selects different menu options using the 1) rotary dial at the center of the NGS, 2) the Trigger bar, 3) or one of the numbered buttons beneath the NGS display window Several vehicle systems can be accessed Rotary Dial Trigger Bar

  4. The EEC-V Interface

  5. EEC-V Diagnostic Links This window displays all modules installed in the vehicle Scroll with the Rotary dial to select the module to test and then, Hit the Trigger bar

  6. Selecting the Test Function - EEC -V • Diagnostic Test Modes • Selects type of test to run • PID/Data Monitor and Record • Select data stream parameters to monitor and record for future reference • Active Command Mode Selects PCM outputs to activate various components • Module Identification • Selects Module to Test • Diagnostic Trouble Code Library • Look-up library of DTC definitions

  7. Diagnostic Functions and Data - EEC-V • DTCs and several diagnostic tests are available from this menu • KOEO and KOER • self-tests are selected • on EEC-V using the scan tool • Current status of all monitor Readiness Tests is selected by scrolling up and down the menu list until the item is highlighted and hitting Trigger (More on this later)

  8. Receive/Clear Continuous Codes - EEC-V • The scan tool will • display any • Continuous Codes • stored in memory Code Description • Use the Rotary dial • to select the DTC you want • information about and hit • the Trigger bar • The code description for the highlighted DTC will be shown in the lower box of the display window

  9. Preparing Vehicle for KOEO and KOER On Demand Self Tests - EEC-V This screen prompts you to prepare the vehicle for either KOEO or KOER On Demand Self-Tests by bringing the engine to normal operating temperature

  10. Displaying DTCs from On Demand Self-Test - EEC-V If any DTCs are stored during the On Demand Self-Test they will be shown in the display window

  11. Options: START- Repeats code retrieval PRINT- Prints DTCs STORE- Places all DTCs in the NGS memory C-ALL - Clears all codes C-ONE - Clears the highlighted code

  12. System Readiness - EEC-V If you select On Board System Readiness Tests A display will appear to inform you of the system’s current Readiness Status

  13. More test information available from the System Readiness Display TESTS - Displays current status of all monitors MIL - Displays a window telling you which module triggered the DTC and turned on the MIL CONT - Sends you to the Generic OBD II functions list

  14. Readiness Status Display The Readiness Status Display gives you the current Complete/ Incomplete status of all monitors TIP: You can view this display during a test drive to see if and when various monitors run to completion

  15. Using Active Command Modes - EEC-V Select ACTIVE COMMAND MODES with the Rotary Dial and hit Trigger QUESTION: What does Active Command Modes do? ANSWER: It allows you to activate components. A separate set of commands in this menu also lets you erase Keep Alive Memory and Transmission data

  16. Output Test Mode - EEC-V OUTPUT TEST MODE is available from the ACTIVE MODES menu When you select OUTPUT TEST MODE, the PCM starts to activate all actuators it can control by alternately turning them ON and OFF

  17. Output Test Modewith PID Monitor If you hit START, the PCM will begin to operate actuators Select PIDs To view an actuator’s response, you must first select it from the list of all devices by marking its PID In this slide, NO devices have been selected for monitoring. No PID data will be displayed until a PID (or PIDs) is selected

  18. Identifying and Selecting PIDs to View • To select a PID • for viewing • in Output • Test Mode: • Scroll to the PID and hit the Trigger bar * TOTAL BOX • An asterisk (*) • will appear next • to any PID that • is selected • The TOTAL box will indicate • the total number of PIDs you • have selected for monitoring

  19. Watching the Test Results Now hit the START button The ON/OFF status of a selected PID (or PIDs) will be shown on the display so you can see if device is actually responding to the commands START

  20. Summary • The EEC-V Interface supports: • Separate interfaces for various vehicle modules including Module Identification • Retrieve/Clear Continuous Codes • KOEO On Demand Self-Test • KOER On Demand Self-Test • PID/DATA Monitor • On Board System Readiness Test • Active Command Mode • PCM Reprogramming

  21. Using the OBD II Test Interface on Ford Vehicles

  22. OBD II Test Menu Use Scroll Dial to highlight selection and hit Trigger TIP! The arrow to the right of the display indicates that there are more options available using the scroll dial These selections allow you to retrieve more information or execute commands

  23. CONT Additional Menu Items • DIAGNOSTIC MONITORING RESULTSlists all test data from the last oxygen sensor tests • PENDING TROUBLE CODESlists any maturingcodes that may store a DTC and turn on the MIL if they are detected again on the next trip • ON BOARD SYSTEM READINESS TEST RESULT lists the pass/fail status of the monitors the last time they ran • EXPANDED DIAGNOSTIC PROTOCOL allows you to manually enter or retrieve and existing numeric string

  24. Readiness Tests - OBD II Interface TESTS lists all system Monitors and their Complete or Incomplete Status • Arrows to the right • of the text indicate • that there are more • lines of data available • TIP! Use Rotary dial to scroll down list and view items not visible on initial display

  25. MIL Module Identification Screen - OBD II Interface Identifies which module turned on MIL CANCEL Bar TIP!Hit CANCEL bar to return to main menu

  26. PID/DATA Monitor - OBD II If PID/DATA MONITOR is highlighted and selected with the TRIGGER bar, all data parameters for the vehicle will be displayed highlighted TIP! The term PID simply means ParameterIDentification. In other words, it is one item on the data display

  27. Selecting PIDs - OBD II Scroll through the list with the Rotary Dial, and hit TRIGGER to select individual PIDs. MAX Button An asterisk (*) will appear next to any selected item TIP! To Select ALL PIDs, hit MAX

  28. Special Function Buttons • DEFN -Gives • the definition • of highlighted PID • CLEAR - Clears all selections • so you can start PID selection • from scratch • BLOCK - Selects a Block of PIDs. Highlight one PID. Hit the BLOCK key. Rotate the scroll dial until all the PIDs in a series are highlighted

  29. DEFN Button The DEFN is very useful since there are so many PIDs to identify. Definition The definition of the highlighted PID is displayed at the bottom of the screen so you don’t have to look up each definition separately in a reference manual

  30. Viewing PIDs OBD II After selecting PIDs by turning the Rotary Dial, hitSTART START Data on the status of each selected PID and the Module (NODE) providing the data is displayed TIP! Selecting too many PIDS will slow the update rate.

  31. Viewing Freeze Frame -OBD II In the OBD II Menu, use the Scroll Dial to highlight FREEZE FRAME PID DATA Trigger Hit the TRIGGER bar

  32. Freeze Frame Data - OBD II • Accessed from • OBD II • Function Menu • Data is from • first DTC stored UP DOWN Buttons • Use UP or DOWN buttons to scroll though list • Data from a previously stored DTC may be overwritten by a DTC caused by Fuel or Misfire A total of 11 Fuel or Misfire codes have priority over other codes when Freeze Frame is stored

  33. Freeze Frame Data Parameters The following Freeze Frame data parameters may be viewed by scrolling with the Rotary Dial: Acronym/PID Description Unit ECT Engine Coolant Degrees FUELB1 Open/Closed Loop B1 Percent FUELB2 Open/Closed Loop B2 Percent LFT1 Long Term Fuel Trim B1 Percent LFT2 Long Term Fuel trim B2 Percent LOAD Calculated Engine Load Percent RPM Engine speed RPM SFT1 Short Term Fuel Trim B1 Percent SFT2 Short Term Fuel Trim B2 Percent VSS Vehicle Speed MPH/KMH

  34. More Menu Options from the OBD II Menu OXYGEN SENSOR TESTS • DIAGNOSTIC • TROUBLE CODES • or CLEAR DIAGNOSTIC • TROUBLE CODES allow • you to view and erase DTCs • OXYGEN SENSOR TESTS • menu option allows you to view • test data from the last time the oxygen sensor monitor ran

  35. Oxygen Sensor Test Data OBD II Interface • Rich-to-Lean • and • Lean-to-Rich • voltages • Low and High sensor voltage for switch time calculation • Rich-to-Leansensor switch time

  36. Is O2 Sensor Data Live? After selecting from the data options list, numeric data from the last Oxygen Sensor test will be displayed This is NOT live data, only the recorded test results TIP! Use this information to confirm proper oxygen sensor operation in each test mode

  37. Summary • Ford OBD II Interface Supports: • PID Data Monitor • Freeze Frame • DTCs • Clear DTCs • Pending Trouble Codes • Oxygen Sensor Test Results • On Board System Readiness Tests
