Some of the information shown in text or illustrations is obtained using optional equipment. A Sales Representative can determine option availability. This section contains a list of conventions used. 1 Safety Messages Refer to “Safety Precautions” on page i.
Using This Manual Questions and Responses Messages and user responses are CAPITALIZED. Example: The Scan Tool displays the Pending DTCs or a message stating SYSTEM PASS: NO FAULT DETECTED. Manual References 1 Used to reference other sections of the manual. References include the “Title” and page number (section-page). Example: For more information on DTCs, refer to “Diagnostic Link Connectors (DLC)” on page 2-3.
Section 2 – Getting Started The Professional Enhanced Scan Tool was developed by experts in the automotive service industry to help diagnose vehicles and assist in troubleshooting procedures. The tool monitors vehicle events and retrieves codes from the vehicle computer’s memory to pinpoint problem areas. All information, illustrations and specifications contained in this manual are based on the latest information available from industry sources at the time of publication.
Getting Started The original on-board diagnostics (OBD I) lacked consistency in communication and interface while allowing different interpretations amongst vehicle manufacturers. Ford and Chrysler used different types of engine control computers and data link connectors, and GM varied the trouble codes and communication protocols from year-to-year. The tables below highlight changes for GM, Ford, and Chrysler. If this seems confusing; don’t worry. Your tool makes it easy.
Getting Started OBD II stands for On-Board Diagnostics version II. OBD II is a system that the Society of Automotive Engineers (SAE) developed to standardize automotive electronic diagnosis. Technicians now can use the same tool to test any OBD II compliant vehicles without special adapters. The SAE established guidelines that provide: • a universal diagnostic test connector, called the data link connector (DLC), with dedicated pin assignments.
Getting Started the dashboard on the driver side of the vehicle. If the DLC is not located under the dashboard as stated, a decal describing its location should be attached to the dashboard in the area the DLC should have been located. Because the OBD II J1962 connector has power and ground, you only need a single cable connection to the tool for both power and tool communications. Attach the OBD II adapter cable to the extender cable, both supplied with the tool, to connect the tool.
Getting Started MECS MECS vehicles (1988 –1995) use either a 6-pin (with pigtail) or a 17-pin DLC. Use the MECS 6-pin adapter cable kit (P/N 9603) for both configurations. The MECS adapter cable kit includes jumper wires to connect to the MECS 17-pin DLC. The MECS adapter cable kit is not included with this tool. It is available through your dealer. Use the following diagrams to connect the adapter cable.
Getting Started MECS Ford Probe Certain Ford Probes have a WHITE TACH CONNECTOR IMPORTANT located very close to the 6-pin Self-Test connector and bundled in the same wiring harness. This is NOT the STI (Self Test Input) Pigtail. Connect the pigtail to the BLACK STI connector located farther back on the wire harness. If the tool is connected to the WHITE Tach connector, serious damage will result and may void warranty. Refer to the illustration.
Getting Started Chrysler Historic Prior to 1996, most Chrysler vehicles used either the SCI or LH DLC. Refer to “Appendix A - Data Link Connectors" for DLC type and location. The SCI adapter cable is included with the scan tool. The LH adapter cable (P/N 9605) can be purchased from your dealer. IMPORTANT Use the Battery Power cable to provide 12V to the tool when using the SCI adapter cable. SCI SCI The SCI (serial communications interface) DLC is a 6-pin connector located in the engine compartment.
Getting Started Within each general category, the DTCs are assigned to specific ranges that cover certain vehicle systems.

Using The Scan Tool CONNECTING THE SCAN TOOL To diagnose a vehicle, connect the DLC and power adapter (if applicable) to the scan tool. Refer to “Diagnostic Link Connectors (DLC)” on page 2-3 of Getting Started. Diagnostic Connector If you just want to power up the tool to do its self-tests, code lookup, review or printing data from the last vehicle tested, then you do not need to attach the cable to the Data Link Connector. The internal battery provides power for this.
Using The Scan Tool Changing the Vehicle Changing vehicles erases all data stored in the tool. The default is YES. Press ENTER to continue. Picking New Vehicle Erases All Stored Data. Continue? NO Four Vehicle Options are available: General Motors, Ford, Chrysler and Global OBD II. Global OBD II does not require additional information and takes you directly to the function list. The other three require additional information so that the tool can communicate with the vehicle.
Using The Scan Tool User Interface The scan tool is designed to be as intuitive as possible. All menu and lists operate the same way. Use the UP/DOWN arrow keys to move UP/DOWN through the display or move the cursor (`) to a selectable item. Press the ENTER key to select the function or item. To return to previous screens, press the BACK key. This information can be viewed on the scan tool by pressing the HELP key after powering up the scan tool.
Using The Scan Tool Custom Data List The Custom Data List allows you to select certain PIDs from the Entire Data List, such as those PIDs that pertain to a specific driveability symptom or system. The scan tool asks if you want to view the instructions. Once in the Custom Data List menu, follow the instructions described below. A « symbol will be displayed next to all selected PIDs. Use the UP/DOWN arrow keys to scroll through the list.
Section 4 – Global OBD II Diagnostics The first time the scan tool communicates with the vehicle, the communication type is automatically detected, and is used until the scan tool is turned OFF or another vehicle is diagnosed. ✓ ✓ If an Error Message displays, make sure the OBD II connector is securely attached, and the ignition key is ON. Cycle the ignition key to OFF for 10 seconds, then ON. This may be required to reset the computer. If required, select YES to try again.
Global OBD II Diagnostics Select I/M Readiness from the OBDII Function List menu and press ENTER . The scan tool displays a message stating whether the I/M Readiness monitors are completed.

Global OBD II Diagnostics After making a selection, press ENTER to establish a communication link. Multiple PIDs may be sent if the vehicle is equipped with more than one computer module — Powertrain Control Module (PCM), Transmission Control Module (TCM), etc. The scan tool identifies them by their identification names (ID) assigned by the manufacturer (i.e. $40 or $1F).
Global OBD II Diagnostics O2 MONITOR TEST ✓ The O2 Monitor Test is NOT AN ON-DEMAND TEST. O2 sensors are NOT tested when selected via the menu. The O2 sensors are tested when engine operating conditions are within specified limits. OBD II regulations require that applicable vehicles monitor and test the oxygen (O2) sensors to determine problems related to fuel and emissions. The O2 Monitor Test allows retrieval of completed O2 sensors monitor test results.
Global OBD II Diagnostics NON-CONTINUOUS TESTS The Non-Contin (Non-Continuous) Tests obtains test results for emission-related powertrain components and systems that are not continuously monitored. The Non-Contin Test function is useful after servicing or after erasing the vehicle’s memory. Test results do not necessarily indicate a faulty component or system. The scan tool asks the vehicle for any available non-continuous test IDs, and then displays them in a list.
Global OBD II Diagnostics Select On-Board Systems from the OBDII Function List and press ENTER. A list of on-board systems and components available for testing display on the screen.

GM Enhanced (OBD II) Diagnostics GM ENHANCED (OBD II) DIAGNOSTICS IMPORTANT ✓ ✓ ✓ This system applies to GM vehicles manufactured from 1996 to present. Some GM vehicles in 1994 and 1995 were equipped with this system. Refer to “Appendix A - Data Link Connectors". GM vehicles manufactured from 2000 to present automatically use Global OBD II Diagnostics. If an Error Message displays, make sure the OBD II connector is securely attached, and the ignition key is ON.
GM Enhanced (OBD II) Diagnostics • Since IGN (ignition): PASS, FAIL, P/F, or NOT RUN Provides the DTC status during this power-up. P/F (Pass/Fail) indicates the PCM detected the DTC that passed and failed at least once during this power-up cycle. NOT RUN means the PCM has not tested for the condition that set the DTC during this power-up cycle. • Since Clear: PASS, FAIL, P/F, or NOT RUN Provides the DTC status since the last time the codes were erased.
