BLCKTEC 400: How to scan for Check Engine Light

Purpose

To guide you on how to scan the check engine light while using the BLCKTEC 400.

Step 1 - Turn the Ignition off.

Turn off the ignition.

Step 2 - Locate the vehicle's 16-pin Data Link Connector (DLC).

Some DLCs have a plastic cover that should be removed before connecting the Scan Tool.

Step 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 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.

Step 4 - Turn the ignition on. DO NOT start the engine.

Turn on the Ignition but do not start the engine.

Step 5 - When the Code Reader is properly connected to the vehicle’s DLC, the unit itself will automatically turn 'On.'

If the unit does not power on automatically, it may indicate there is no power present at the vehicle’s DLC connector. Check the fuse panel and replace any burned-out accessory fuses.

If replacing the accessory fuse(s) does not correct the problem, consult the vehicle’s repair manual to identify the proper computer (PCM) fuse/circuit, and perform any necessary repairs before proceeding.

After 4-5 seconds, the Code Reader will retrieve and display any Diagnostic Trouble Codes that are in the vehicle's computer memory.

Step 6 - After plugging in the tool, a confirmation message will show up.

By plugging in the device, make sure that you get an image of the 'READ'

Step 7 - The Diagnostic Tool will retrieve and display any Diagnostic Trouble Codes (DTCs).

After reading your vehicle's system, a list of DTCs will appear on the screen related to all issues associated with your Check Engine Light.
