BLCKTEC 440: Erasing Diagnostic Trouble Codes (DTCs)
Purpose
To guide you on how to erase your DTCs while using the BLCKTEC 440.
Erasing DTCs
When the scan tool ERASE function is used to erase the DTCs from the vehicle’s onboard computer, Freeze Frame data, and the manufacturer-specific enhanced data are also erased. The Permanent DTCs are not erased by the ERASE function.
Make sure that If you plan to take the vehicle to a service center for repair, do not erase the codes from the vehicle's computer. If the codes are erased, then valuable information that might help your service technician to troubleshoot the problem will also be erased.
When DTCs are erased, the I/M Readiness Monitor status resets the status of all monitors to a no-run condition. To properly set all monitors to a done status, an OBD2 Drive Cycle must be performed.
Step 1 - Connect the Diagnostic Tool to the vehicle’s DLC, and turn the ignition ON, but do not start the engine.
If the scan tool is already connected and linked to the vehicle’s computer, proceed directly to step 3. If not, continue to step 2.
Step 2 - Perform the Code Retrieval procedures.
|
After scanning your vehicle and retrieving a list of DTCs, to erase the DTCs, wait until the codes are displayed for your desired module. |
Step 3 - Press and release ERASE button.
|
After viewing your codes, select the ERASE button. |
|
A confirmation message will show. If you're sure you want to proceed, press the DOWN ▼ button to scroll down, then select Yes to continue, then press ENTER ↵. If you do not want to proceed, select No, then press ENTER ↵ to cancel the erase procedure. |
Step 4 - A One moment please message will display while the erase function is in progress.
|
If you choose to erase DTCs, a One moment please message will display while the erase function is in progress. If the erase was not successful, an advisory message displays indicating that the erase request was sent to the vehicle’s computer. After 3 seconds, the scan tool will automatically relink to the vehicle’s computer. |
Note: If the erase was successful, a confirmation message shows. The scan tool automatically relinks to the vehicle’s computer after 3 seconds.
