CP9125 OBD II PocketScan Code Reader For use with OBD II Compliant Vehicles 1 4 2 3 1 LCD Display - Is a Single Line Display with 8 characters. 2 ERASE Key - Used to Erase Trouble Codes and I/M Monitor status from Vehicles Computer Modules and scroll up through screens. (I/M Monitors are currently used for state emissions tests.) 3 READ/Scroll Down Key - Used to view Read Codes, MIL Status, I/M Readiness Status and Scroll down through screens.
Safety Precautions For safety, read, understand and follow all safety messages and instructions in manual before operating the PocketScanTM Code Reader. Always refer to and follow safety messages and test procedures provided by manufacturer of vehicle and PocketScanTM Code Reader. Signal Words Used: Indicates a possible hazardous situation ! DANGER which, if not avoided, will result in death or serious injury to operator or bystanders.
Always use caution when working around ignition coil, distributor cap, ignition wires, and spark plugs. Components can produce a High Voltage while engine is running. Battery acid is caustic. If contacted, rinse with water or neutralize with a mild base (i.e. baking soda). If in eyes, flush with water and call a physician immediately. Never smoke or have open flames near vehicle. Vapors from gasoline and battery during charge are explosive.
PocketScanTM Code Reader Features Read Codes: Reading Diagnostic Trouble Codes allows the PocketScanTM Code Reader to read the codes from the vehicles computer modules. Diagnostic Trouble Codes: P0443 : 9 Diagnostic Trouble Codes are used to help determine the cause of a problem or problems with a vehicle. Diagnostic Trouble Codes are set when a fault is present for a sufficient amount of time. Pending Codes: Pending Codes are also referred to as continuous monitor codes and maturing codes.
MIL Conditions: MIL (Malfunction Indicator Lamp) Status displays the state of the vehicles computer module(s). MIL ON: Indicates that the Malfunction Indicator Lamp on vehicle should be ON indicating a possible emissions problem. MIL ON : 9 √ If the MIL Status is ON and the MIL is not illuminated with the engine running, then a problem exists in the MIL circuit. MIL OFF: Indicates the Malfunction Indicator Lamp should be off and there should be no emission problems.
Inspection / Maintenance Monitors (I/M Monitors): The I/M Monitors (Inspection / Maintenance) function displays a SNAPSHOT of the operations for the Emission System. √ After a specific amount of drive time (each monitor has specific driving conditions and time required), the computers monitors will decide if the vehicles emission system is working correctly. √ Some states MAY NOT require all monitors listed to be Ready to pass the emissions test.
Reading Diagnostic Trouble Codes and Data Cooling Fan! Fan may turn on ! WARNING Avoid during test. O 1.Turn Ignition Key to the Off Position. FF ON 2. Locate and Plug in Data Link Connector (DLC.) NOTE: The data link connector should be located under the dashboard on the driverside of the vehicle. If the data link connector is not located under the dashboard as stated, a label describing the location of the data link connector should be there. 3. Observe Display toggles between Pocket and Scan.
NOTE: If diagnostic trouble codes (DTCs) are already being displayed from a previous read operation, press and hold READ/Scroll Down key for 3 seconds and release. 6.Observe a Moving * on Display. * No Link NOTE: If a No Link message displays, cycle ignition key to the OFF position for 10 seconds, then back ON and repeat Reading Diagnostic Data. 7.
8. View MIL Status Press and release MIL ON : 9 READ/Scroll Down key. 9. View I/M Monitors that are Incomplete. Press and release Monitrs9 : READ/Scroll Down key. 2 Inc : 9 : Misfire 9 NOTE: If there are no more I/M Monitors that are Incomplete, the tool will then display Ready Monitors when : 5 Ready 9 READ/Scroll Down key is pressed. 10. View I/M Monitors that are Ready. Press and release O2 : Htr 9 READ/Scroll Down key.
Erasing Diagnostic Trouble Codes and Data Erasing allows the PocketScanTM Code Reader to delete the codes and I/M Monitor status from the vehicles computer modules. IMPORTANT Only Erase Diagnostic Data after checking system completely and writing down results. ! WARNING Avoid Cooling Fan! Fan may turn on during test. O 1.Turn Ignition Key to the Off Position. FF ON 2. Locate and Plug in Data Link Connector (DLC.
5.Press and Hold ERASE Key for 3 Seconds and Release. 6.Observe ERASE? Displays. ERASE? 7.Press and Hold ERASE Key for 3 Seconds and Release. 8.Observe a Moving - on Display. NOTE: If a NO LINK message displays, cycle ignition key to the OFF position for 10 seconds, then back ON, and repeat Erasing Diagnostic Data. 9.Observe DONE Displays. - NO LINK DONE NOTE: If the problem causing Diagnostic Trouble Code(s) still exists, the code will return.
