Code Scanner Functions

1.Connect the Code Scanner to the vehicle DLC, it will not harm the vehicle.

2.The name and software ID displays momentarily.

3.Press ENTER to go to the Main Menu.

4.The display contrast can be adjusted for different viewing angles. Select Display Contrast and use the UP / DOWN arrow keys to increase and de- crease the contrast. The setting will remain even when the power is disconnected.

CAUTION!

Avoid Cooling Fan! It May Turn On During Test.

NOTE: If an Operating Error message is displayed, make sure the OBD II J1962 adapter cable 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 PCM. Press the BACK key to test again. If the problem still exists, refer to Troubleshooting Tips.

NOTE: Do not disconnect the Code Scanner until codes have been recorded. When power is removed, Code Scanner memory is cleared.

Read Codes

The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from the vehicle’s computer modules. This function can be performed with the Key On-Engine Off (KOEO) or Key On-Engine Running (KOER). Because DTCs indicate a circuit or system failure (not component failures) they are very useful in isolating vehicle system malfunctions. There are two types of codes, Malfunction Indicator Lamp (MIL) codes and Pending codes. An icon (;) will be displayed next to DTCs that are Pending codes.

MIL Codes: These codes cause the computer to illuminate the MIL when an emis- sion related or driveability fault occurs. The MIL is also known as the “service engine soon” or “check engine lamp”. The computer illuminates the MIL when the engine is running and the DTC remains in memory until the fault is repaired.

Pending Codes: These codes are also referred as “continuous monitor” and “matur- ing codes”. An intermittent fault causes the computer to store a code in memory. If the fault does not occur within 40 warm-up cycles, the code will be cleared from memory. If the fault occurs a specific number of times, the code matures into a DTC and the MIL turns on.
