This manual describes common test procedures used by experienced service technicians. Many test procedures require precautions to avoid accidents that can result in personal injury, and/or damage to your vehicle or test equipment. Always read your vehicle's service manual and follow its safety precautions before and during any test or service procedure. ALWAYS observe the following general safety precautions: When an engine is running, it produces carbon monoxide, a toxic and poisonous gas. To prevent serious injury or death from carbon monoxide poisoning, operate the vehicle ONLY in a well-ventilated area. To protect your eyes from propelled objects as well as hot or caustic liquids, always wear approved safety eye protection. When an engine is running, many parts (such as the coolant fan, pulleys, fan belt etc.) turn at high speed. To avoid serious injury, always be aware of moving parts. Keep a safe distance from these parts as well as other potentially moving objects. Engine parts become very hot when the engine is running. To prevent severe burns, avoid contact with hot engine parts. P RND L Before starting an engine for testing or troubleshooting, make sure the parking brake is engaged. Put the transmission in park (for automatic transmission) or neutral (for manual transmission). Block the drive wheels with suitable blocks. Connecting or disconnecting test equipment when the ignition is ON can damage test equipment and the vehicle's electronic components. Turn the ignition OFF before connecting the Scan Tool to or disconnecting the Scan Tool from the vehicle’s Data Link Connector (DLC). To prevent damage to the on-board computer when taking vehicle electrical measurements, always use a digital multimeter with at least 10 megOhms of impedance. Fuel and battery vapors are highly flammable. To prevent an explosion, keep all sparks, heated items and open flames away from the battery and fuel / fuel vapors. DO NOT SMOKE NEAR THE VEHICLE DURING TESTING. Don't wear loose clothing or jewelry when working on an engine. Loose clothing can become caught in the fan, pulleys, belts, etc. Jewelry is highly conductive, and can cause a severe burn if it makes contact between a power source and ground. 1 Scan Tool Controls CONTROLS AND INDICATORS CONTROLS AND INDICATORS 14 13 11 12 10 7 1 2 4 5 3 6 8 9 20 15 16 17 18 19 Figure 1.

Never replace a part based only on the DTC definition. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the location of the problem. Always refer to the vehicle's service manual for detailed testing instructions. Check your vehicle thoroughly before performing any test. ALWAYS observe safety precautions whenever working on a vehicle. 1. Turn the ignition off. 2. Locate the vehicle's 16-pin Data Link Connector (DLC). Some DLCs have a plastic cover that must be removed before connecting the Scan Tool cable connector. If the Scan Tool is ON, turn it OFF BEFORE connecting the Scan Tool to the DLC. 3. Connect the Scan Tool to the vehicle’s DLC. The cable connector is keyed and will only fit one way. If you have problems connecting the cable connector to the DLC, rotate the connector 180°. If you still have problems, check the DLC on the vehicle and on the Scan Tool. 4. Turn the ignition on. DO NOT start the engine. 5. When the Scan Tool is properly connected to the vehicle’s DLC, the unit automatically turns ON. If the unit does not power on automatically, it may indicate there is no power present at the vehicle’s DLC connector. Check the fuse panel and replace any burned-out fuses. If replacing the fuse(s) does not correct the problem, consult your vehicle’s repair manual to identify the proper computer (PCM) fuse/circuit, and perform any necessary repairs before proceeding. 7 Using the Scan Tool CODE RETRIEVAL PROCEDURE 6. The Scan Tool automatically starts a check of the vehicle’s computer to determine which type of communication protocol it is using. When the Scan Tool identifies the computer’s communication protocol, a communication link is established. A PROTOCOL is a set of rules and procedures for regulating data transmission between computers, and between testing equipment and computers. As of this writing, five different types of protocols (ISO 9141, Keyword 2000, J1850 PWM, J1850 VPW and CAN) are in use by vehicle manufacturers. If the Scan Tool fails to link to the vehicle’s computer, a “Communication Error” message shows. - Ensure your vehicle is OBD2 compliant. - Verify the connection at the DLC, and verify the ignition is ON. - Turn the ignition OFF, wait 5 seconds, then back ON to reset the computer. - Press POWER/LINK to continue.

If no codes are present, the message “No Powertrain DTCs or Freeze Frame Data presently stored in the vehicle’s computer” displays. 9 Using the Scan Tool CODE RETRIEVAL PROCEDURE The Scan Tool is capable of retrieving and storing up to 32 codes in memory, for immediate or later viewing. 11. Refer to DISPLAY FUNCTIONS on page 3 for a description of display elements. In the case of long code definitions, a small arrow is shown in the upper/lower right-hand corner of the Scan Tool display area to indicate the presence of additional information. If a definition for the currently displayed code is not available, an advisory message shows on the Scan Tool’s display. 12. Read and interpret Diagnostic Trouble Codes/system condition using the display and the green, yellow and red LEDs. The green, yellow and red LEDs are used (with the display) as visual aids to make it easier to determine engine system conditions. Green LED – Indicates that all engine systems are “OK” and operating normally. All monitors supported by the vehicle have run and performed their diagnostic testing, and no trouble codes are present. All Monitor icons will be solid. Yellow LED – Indicates one of the following conditions: A. A PENDING CODE IS PRESENT – If the yellow LED is illuminated, it may indicate a Pending code is present. Check the display for confirmation. A Pending code is confirmed by the presence of a numeric code and the word PENDING. B. MONITOR NOT RUN STATUS – If the display shows a zero (indicating there are no DTC’s present in the vehicle’s computer memory), but the yellow LED is illuminated, it may be an indication that some of the Monitors supported by the vehicle have not yet run and completed their diagnostic testing. Check the display for confirmation. All Monitor icons that are blinking have not yet run and completed their diagnostic testing; all Monitor icons that are solid have run and completed their diagnostic testing. 10 Using the Scan Tool CODE RETRIEVAL PROCEDURE Red LED – Indicates there is a problem with one or more of the vehicle’s systems. The red LED is also used to indicate that DTC(s) are present. In this case, the Malfunction Indicator (Check Engine) lamp on the vehicle’s instrument panel will be illuminated. DTC’s that start with “P0”, “P2” and some “P3” are considered Generic (Universal). All Generic DTC definitions are the same on all OBD2 equipped vehicles. The Scan Tool automatically displays the code definitions (if available) for Generic DTC’s. DTC’s that start with “P1” and some “P3” are Manufacturer specific codes and their code definitions vary with each vehicle manufacturer. 13. If more than one DTC was retrieved, and to view Freeze Frame Data, press and release DTC/FF as necessary. Each time DTC/FF is pressed and released, the Scan Tool will scroll and display the next DTC in sequence until all DTCs in its memory have displayed. Freeze Frame Data (if available) will display after DTC #1. In OBD2 systems, when an emissions-related engine malfunction occurs that causes a DTC to set, a record or snapshot of engine conditions at the time that the malfunction occurred is also saved in the vehicle’s computer memory. The record saved is called Freeze Frame data. Saved engine conditions include, but are not limited to: engine speed, open or closed loop operation, fuel system commands, coolant temperature, calculated load value, fuel pressure, vehicle speed, air flow rate, and intake manifold pressure. If more than one malfunction is present that causes more than one DTC to be set, only the code with the highest priority will contain Freeze Frame data. The code designated “01” on the Scan Tool display is referred to as the PRIORITY code, and Freeze Frame data always refers to this code. The priority code is also the one that has commanded the MIL on. 14. When the last retrieved DTC has been displayed and DTC/FF is pressed, the Scan Tool returns to the “Priority” Code. 15. Determine engine system(s) condition by viewing the Scan Tool’s display for any retrieved Diagnostic Trouble Codes, code definitions and Freeze Frame data, interpreting the green, yellow and red LEDs. If DTC’s were retrieved and you are going to perform the repairs yourself, proceed by consulting the Vehicle’s Service Repair Manual for testing instructions, testing procedures, and flow charts related to retrieved code(s). 11 Using the Scan Tool THE SYSTEM MENU - VIEWING OEM ENHANCED DTCs THE SYSTEM MENU The System Menu provides the ability to retrieve “enhanced” DTCs and Anti-Lock Brake System (ABS) DTCs for most BMW, Chrysler/Jeep, Ford/Mazda, GM/Isuzu, Honda/Acura, Hyundai, Mercedes Benz, Nissan, Toyota/Lexus, Volkswagen and Volvo vehicles.

Application Table Definitions. EFI = Electronic Fuel Injection; FBC = Feedback Carburetor; MFI = Multiport Fuel Injection; OHC = Overhead Cam; SC = Super Charged; SEFI = Sequential Electronic Fuel Injection; SFI = Sequential Fuel Injection CODE RETRIEVAL PROCEDURES Overview of Ford Code Retrieval Process Ford's computer self-diagnostic system is divided into four main sections: 1. "Key On Engine Off" (KOEO) Self-Test 2. "Continuous Memory" (CM) Self-Test 3. "Key On Engine Running" (KOER) SelfTest 4. Other EEC-IV System tests These Self-Tests are specially designed to monitor and/or test the various components and circuits that are controlled by the vehicle's computer, and to save and/or transmit diagnostic test results to the Scan Tool in the form of numerical fault codes. The "Continuous Memory" Self-Test is designed to run continuously whenever the vehicle is normal operation. If a fault is detected by the "Continuous Memory" Self-Test, a fault code is saved in the vehicle's computer memory for later retrieval. Ford’s On-Board Diagnostic Self-Tests are designed in such a way that in order to properly diagnose a problem, you must perform all the SelfTests, in the proper sequence. As described previously, some tests are designed to detect problems only when the vehicle is in normal operation. Some tests are designed to activate components and detect problems only with the Key On and Engine Off. Other tests are designed to activate components and test their operation only with the Key On and Engine Running. Do not take short cuts. If you fail to perform a test, or you perform a test out of sequence, you might miss a problem that is only detected during that part of the test. Key On Engine Off (KOEO) Test During the KOEO Self-Test, two groups of codes are retrieved 28 The first group of codes are called "KOEO codes". A "KOEO" icon shows to indicate the code is a "KOEO" code. Ford OBD1 Systems CODE RETRIEVAL PROCEDURES - KOEO TEST The second group of codes are called "Continuous Memory" codes. A "Continuous Memory" icon shows to indicate the code is a "Continuous Memory" code. Check your vehicle thoroughly before performing any test. ALWAYS observe safety precautions whenever working on a vehicle. 1. Locate the vehicle's Data Link Connector (DLC).
