After a system is selected and the scanner establishes communication with the vehicle, the Function
Menu displays. The menu options may include:
- Read Codes
- Clear Codes
- Live Data
- Active Test
- ECU Information
- Special Functions
Not all function options listed above are applicable to all Nissan models. Available options may vary by the year, model, and make of the test vehicle.
1). Read Codes
Read Codes menu lets you read trouble codes found in the control unit.
Typical code status include:
- Present/Permanent/Current Codes
- Pending Codes
- History Codes
Present/Permanent/Current codes stored in a control module are used to help identify the cause of a trouble or troubles with a vehicle. These codes have occurred a specific number of times and indicate a problem that requires repair.
Pending codes are also referred to as maturing codes that indicate intermittent faults. If the fault does not occur within a certain number of drive cycles (depending on vehicle), the code clears from memory. If a fault occurs a specific number of times, the code matures into a DTC and the MIL illuminates or blinks.
History codes are also referred to as past codes that indicate intermittent DTCs that are not currently active.
To read codes from a vehicle:
(1). Scroll with the arrow keys to highlight Read Codes from Function Menu and press the ENTER key.
A code list including code number and its description displays.
(2). Use the up and down arrow keys to scroll through data to select lines, and left and right arrow keys to scroll back and forth through different screens of data.
(3). Press function key Save to store DTC information. Press function key Freeze Frame to view freeze data.
Freeze Frame Data: a snapshot of critical vehicle operating conditions automatically recorded by the on-board computer at the time of the DTC set. It is a good function to help determine what caused the fault.
(4). Use left and right arrow keys to scroll back and forth through different screens of data.
(5). Press function key Save to store freeze frame information. Or use the BACK key to exit.
2). Clear Codes
Clear Codes menu lets you to clear all current and stored DTCs from a selected control module. Also it erases all temporary ECU information, including freeze frame. So make sure that the selected system is completely checked and serviced by technicians and no vital information will be lost before clearing codes.
- To clear codes, make sure that the ignition key is switched to ON with the engine off.
