BLCKTEC 420: Live Data

Purpose

To guide you on how to access your vehicle's Live Data while using the BLCKTEC 420.

Introduction

The Diagnostic Tool lets you view 'real-time' Live Data. This information includes values (volts, rpm, temperature, speed, etc.) and system status information (open loop, closed loop, fuel system status, etc.) generated by the various vehicle sensors, switches, and actuators. These are the same signal values generated by the sensors, actuators, switches, and/or vehicle system status information used by the vehicle’s computer when calculating and conducting system adjustments and corrections. The real-time (Live Data) vehicle operating information (values/status) that the computer supplies to the Diagnostic Tool for each sensor, actuator, and switch, is called Parameter Identification (PID) Data. Each PID (sensor, actuator switch, status, etc.) has a set of operating characteristics and features (parameters) that serve to identify it. The Diagnostic Tool will display this information for each sensor, actuator, switch, or status that is supported by the vehicle under test.

If the vehicle must be driven to perform a troubleshooting procedure, always have a second person to help you. One person should drive the vehicle while the other person observes the Scan Tool data. Trying to drive and operate the Scan Tool at the same time is dangerous and could cause a serious traffic accident.

Step 1 -While linked to the vehicle, start the engine, then press the LD button.

While linked to the vehicle, start the engine, then press the LD button to access Live Data.

Step 2 - Wait for the Scan Tool to establish communication with the vehicle.

A 'One moment please' message will display while the Diagnostic Tool establishes communication with the vehicle. If the Diagnostic Tool fails to establish communication with the vehicle, a 'Communication Error' message will display.

Ensure the vehicle is OBD2 compliant.
Verify the connection at the DLC, and verify the ignition is ON.
Turn the ignition OFF, wait 5 seconds, then back ON to reset the computer.
Select MENU/ENTER ↵ to continue.

Step 3 - View your Live Data Information.

Your Real-time Live Data (PID) information will display for your vehicle.

If Live Data is not supported by the vehicle under test, an advisory message will display. Select the LD button to access Live Data.

Note: The values for the various PIDs displayed may change as the vehicle’s operating conditions change.

Step 4 -Press the DOWN ▼button to view all available PID data.

Only a limited amount of PID data can be displayed on the screen at one time.

If additional PID data is available, a small arrow is shown on the display.

Press the DOWN▼ button, as necessary, to view all available PID data.

If communication with the vehicle is lost while viewing Live Data, an advisory message will display.
