Innova 7111: Powertrain Live Data

Purpose

To demonstrate to you monitoring, graphing, recording, and playback of Powertrain Live Data while using the Innova 7111 Scan Tool Tablet.

Introduction

The Innova 7111 Scan Tool Tablet lets you view and/or record 'real-time' Live Data. This information includes values (voltage, RPM, temperature, speed, etc.) and system status information (open loop, closed loop, fuel system status, etc.). These are the signals used by the vehicle's computer to calculate and make system adjustments and corrections. The real-time (Live Data) vehicle operating information (values/status) that the computer supplies to the scan tool for each sensor, actuator, switch, etc. is called Parameter Identification Data (PID) . Each PID has a set of operating characteristics and features (parameters) that serve to identify it. The Scan Tool displays this information for each sensor, actuator, switch, or status that is supported by the vehicle under test.

Moreover, you can customize and graph the number of PIDs that you wish to display on the Innova 7111.

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

Procedure

Step 1 - Connect Innova 7111 Scan Tool Tablet to the vehicle and select 'OBD2 Diagnostics' function

• First, connect the Innova 7111 Scan Tool to your vehicle via the Diagnostic Link Connector (DLC) to retrieve the vehicle's information, such as Vehicle Identification Number (VIN) and model.

  Then, select the function 'OBD2 Diagnostics'.

Step 2 – Select 'Live Data' function

• Tap the ‘Live Data' button to view your Real-Time Live Data (PID).

  
  

Step 3 - View Live Data (PID) information

• The Innova 7111 Scan Tool Tablet will show a list of supported parameters (as seen in the image). The total number of PIDs is in the top left corner.

  A 'Communication Error' message will display if the Scan Tool fails to establish communication with the vehicle. In this scenario, the user needs to check the following items:

  • 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 turn it back 'ON' to reset the computer. 
  • Press the POWER/LINK button to continue.

Step 4 – Select PIDs to customize information

• In order to perform the Customizing ‘Live Data’ function on the Innova 7111 Scan Tool. 

  Click the box next to each parameter to select the PID you wish to use to customize your report. A ‘checkmark’ will be shown to confirm your selection.

• You can search for the parameter by tapping the ‘Search’ icon.
• Tap the ‘View’ button to view the real-time value of the PIDs that you selected.
• The list of PIDs that you selected will be shown (as seen in the image).

Step 5 –Select the ‘Graph’ button to graph all selected PIDs

• Tap the ‘Graph’ button to display all selected PIDs in graphical form.

• The Innova 7111 Scan Tool Tablet provides the ability to graph all PIDs with value at one time, which allows you to monitor the changes in PID values more clearly.

  The graphs of PIDs that you selected will be shown (as seen in the image).

Step 6 – Performing the 'Record' function

• Tap the ‘Record’ button to record the Live Data Stream.

• Tap the ‘Stop Record’ button to finish the record function.

  Tap the ‘Yes, Save Live Data’ button to save the recorded data when you are finished and want to save it.

• Tap the ‘No, Erase Live Data’ button to finish the record function when you don’t want to save the recorded data.

Step 7 – Playback the recorded data

• Select the ‘Previous Vehicles’ function.
• Tap the ‘Live Data’ button.
• Tap the recorded Live Data based on the date, time, and vehicle information that you want to review.

• Tap the ‘Play’ button to start.

  When viewing recorded Live Data, look for any irregularities in any of the PID values/signal information (LTFT %, RPM, MAP, TEMP, etc.). If any PIDs are not within specification or irregularities are detected, follow the procedures in the vehicle's service repair manual to perform additional troubleshooting and repair.
