About the Code Reader

CONTROLS AND INDICATORS

1. ERASE button – Erases Diagnostic Trouble Codes (DTCs) and “Freeze Frame” data from your vehicle’s computer, and resets Monitor status.
2. DTC button – Scrolls the LCD display to view DTCs when more than one DTC is present.
3. GREEN LED – Indicates that all engine systems are running normally (all Monitors on the vehicle are active and performing their diagnostic testing, and no DTCs are present).
4. YELLOW LED – Indicates there is a possible problem. A “Pending” DTC is present and/or some of the vehicle’s emission monitors have not run their diagnostic testing
5. RED LED – Indicates there is a problem in one or more of the vehicle’s systems. The red LED is also used to show that DTC(s) are present. DTCs are shown on the Car Reader’s LCD display. In this case, the Malfunction Indicator (“Check Engine”) lamp on the vehicle’s instrument panel will light steady.
6. LCD Display – Displays test results, Code Reader functions and Monitor status information. See DISPLAY FUNCTIONS, below, for details.
7. CABLE – Connects the Code Reader to the vehicle’s Data Link Connector (DLC).

DISPLAY FUNCTIONS

1. I/M MONITOR STATUS field – Identifies the I/M Monitor status area.
2. Monitor icons – Indicate which Monitors are supported by the vehicle under test, and whether or not the associated Monitor has run its diagnostic testing (Monitor status). When a Monitor icon is solid green, it indicates that the associated Monitor has completed its diagnostic testing. When a Monitor icon flashes red, it indicates that the vehicle supports the associated Monitor, but the monitor has not yet run its diagnostic testing. The I/M Monitor Status icons are associated with INSPECTION and MAINTENANCE (I/M) READINESS STATUS. Some states require that all vehicle Monitors have run and completed their diagnostic testing before a vehicle can be tested for Emissions (Smog Check). A maximum of fifteen Monitors are used on OBD2 systems. Not all vehicles support all fifteen Monitors. When the Diagnostic Tool is linked to a vehicle, only the icons for Monitors that are supported by the vehicle under test are visible on the display.
3. Link icon – Indicates whether or not the Code Reader is communicating (linked) with the vehicle’s on-board computers. When visible, the Code Reader communicates with the computers. If the Link icon is not visible, the Code Reader is not communicating with the computers.
4. Vehicle icon – Indicates whether or not the Code Reader is being properly powered through the vehicle’s Data Link Connector (DLC). A visible icon indicates that the Code Reader is being powered through the vehicle’s DLC connector.
5. MIL icon – Indicates the status of the Malfunction Indicator Lamp (MIL). The MIL icon is visible only when a DTC has commanded the MIL on the vehicle’s dashboard to light.
6. HISTORY icon – Indicates the currently displayed DTC is a “History” code.
7. FREEZE FRAME icon – Indicates that “Freeze Frame” data has been stored in the vehicle’s computer for the currently displayed DTC.
8. PENDING icon – Indicates the currently displayed DTC is a “Pending” code.
9. PERMANENT icon – Indicates the currently displayed DTC as a “Permanent” code.
10. DTC Display Area – Displays the Diagnostic Trouble Code (DTC) number. Each fault is assigned a code number that is specific to that fault.
11. Code Number Sequence – The Code Reader assigns a sequence number to each DTC that is present in the computer’s memory, starting with “01.” This helps keep track of the number of DTCs present in the computer’s memory. Code number “01” is always the highest priority code and the one for which “Freeze Frame” data has been stored.
12. Code Enumerator – Indicates the total number of codes retrieved from the vehicle’s computer.

CODE RETRIEVAL PROCEDURE

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. This information is found in the vehicle’s service manual. Always refer to the vehicle’s service manual for detailed testing instructions

1. Turn the ignition off.
2. Locate the vehicle’s 16-pin Data Link Connector (DLC).
3. Connect the Code Reader’s cable connector 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° and try again. If you still have problems, check the DLC on the vehicle and on the Code Reader. Refer to your vehicle’s service manual to properly check the vehicle’s DLC.
   • After the Code Reader’s test connector is properly connected to the vehicle’s DLC, the Vehicle icon should display to confirm a good power connection.
4. Turn the ignition on. DO NOT start the engine.
5. The Code Reader will automatically link to the vehicle’s computer.
   • If the LCD display is blank, it indicates there is no power at the vehicle’s DLC. Check your fuse panel and replace any burned-out fuses. If replacing the fuse(s) does not correct the problem, see your vehicle’s repair manual to locate the proper computer (PCM) fuse/circuit. Perform any necessary repairs before continuing.
   • After 4-5 seconds, the Code Reader will retrieve and display any Diagnostic Trouble Codes that are in the vehicle’s computer memory.
6. Read and interpret the Diagnostic Trouble Codes using the LCD display and the green, yellow, and red LEDs.
   • The green, yellow, and red LEDs are used (with the LCD display) as visual aids to make it easier for the user to determine engine system conditions.
   • Green LED – Indicates that all engine systems are “OK” and running normally. All monitors on the vehicle are active and are performing their diagnostic testing, and no trouble codes are present. A zero will show on the Code Reader’s LCD display for further confirmation.
   • Yellow LED – Indicates one of the following conditions:
   • PENDING CODE PRESENT – If the yellow LED is lit, it may indicate the existence of a pending code. Check the Code Reader’s LCD display for confirmation. A pending code is confirmed by the presence of a numeric code and the word PENDING on the Code Reader’s LCD display. If no pending code is shown, the yellow LED indicates Monitor Status (see the following).
   • Red LED – Indicates there is a problem with one or more of the vehicle’s systems. The red LED is also used to show that DTC(s) are present (displayed on the Code Reader’s LCD display). In this case, the Malfunction Indicator (Check Engine) lamp on the vehicle’s instrument panel will light steady on.
7. If more than one code is present, press and release the DTC button, as necessary, to display additional codes. Visit the manufacturer’s website for Fault Code Definitions. Match the retrieved DTC(s) with those listed. Read the associated definition(s), and see the vehicle’s service manual for further evaluation.

CHECKING THE FIRMWARE VERSION

You can check the firmware version of your Code Reader.

1. Press and hold the DTC button while you connect the Code Reader to the vehicle’s DLC.
   • The Firmware Version screen displays.
   • The screen shows the tool’s current firmware version.
2. Press the DTC button again to exit

Using the Code Reader

ERASING DIAGNOSTIC TROUBLE CODES (DTCs)

Erase DTCs from the computer’s memory as follows:

When DTCs are erased from the vehicle’s computer memory, the I/M Readiness Monitor Status program resets the status of all the Monitors to a not run “flashing” condition. To set all of the Monitors to a DONE status, an OBD2 Drive Cycle must be performed. Refer to your vehicle’s service manual for information on how to perform an OBD2 Drive Cycle for the vehicle under test.

1. If not connected already, connect the Code Reader to the vehicle’s DLC. (If the Code reader is already connected and linked to the vehicle’s computer, proceed directly to step 4. If not, continue to step 2.)
2. Turn the ignition on. DO NOT start the engine. The Code Reader will automatically link to the vehicle’s computer.
3. Press and release the Code Reader’s ERASE button. The LCD display will indicate “SuRE?” for your confirmation.
   • If you change your mind and do not wish to erase the codes, press the DTC button to return to the code retrieval function.
   • If you wish to continue, press the ERASE button again. When all retrievable information, including DTCs, has been cleared from the computer’s memory, the Code Reader will re-link to the vehicle’s computer and the LCD display will show “0.”
   • Erasing DTCs does not fix the problem(s) that caused the code(s) to be set. If proper repairs to correct the problem that caused the code(s) to be set are not made, the code(s) will appear again (and the check engine light will illuminate) as soon as the vehicle is driven long enough for its Monitors to complete their testing.
