Innova SDS50 SDS-Tech: Powertrain Live Data

Purpose

To explain to you on monitoring, graphing, recording, and playback of Powertrain Live Data while using the Innova SDS50 SDS-Tech Tablet Scan Tool.

Introduction

The Innova SDS50 SDS-Tech Tablet Scan Tool lets you view and/or record 'real-time' Live Data. This information includes values (voltage, revolution per minute (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 Electronic Control Unit (ECU) to calculate and make system adjustments and corrections. The value of Live Data that ECU supplies to the Scan Tool for each sensor, actuator, switch, etc. is called Parameter Identification (PID) Data. Each PID has a set of operating characteristics and features that serve to identify it.

Moreover, you can customize and graph the number of PIDs that you wish to display on the Innova SDS50 SDS-Tech Tablet Scan Tool.

Warning: 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'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 SDS50 SDS-Tech Tablet Scan Tool to the vehicle and select 'OBD2 Diagnostics'

  • First, connect the Innova SDS50 SDS-Tech Tablet 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 'OBD2 Diagnostic' function.

Step 2 - Select 'Live Data' function

  • Select the ‘Live Data' button to view your vehicle's Live Data or PIDs list.
  • The Innova SDS50 SDS-Tech Tablet Scan Tool will show a list of supported parameters as the image.
  • 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 3 - Customizing the Live Data

  • Firstly, you must in the Live Data function. After that, select the ‘Custom’ button to enable the check box of PIDs.
  • Tick the box next to each PID name to select the PID you wish to show in custom mode. A ‘checkmark’ will be shown to confirm your selection.
  • Select the ‘Done' button to view the value of the PIDs that you selected.
  • The list of PIDs that you selected will be shown as the image.
  • To select other PIDs, you can navigate back to the PID selection screen by selecting the ‘View All’ button and selecting the ‘Custom’ button continuously.

Step 4 - Select the ‘Graph’ button to graph all selected PIDs

  • Select the ‘Graph’ button to display the current PIDs in graphical form.
  • The Innova SDS50 SDS-Tech Tablet Scan Tool Tablet provides the ability to graph a maximum of 4 PIDs with value at a time. It allows you to monitor the changes in PID values more clearly.
  • The graphs of PIDs that you selected will be shown as the image.
  • In the graph mode, the Scan Tool allows changing the PID value wishing to be shown by selecting the ‘V’ arrow next to the PIDs name. After that, the Scan Tool shows a PID list for choosing.

Step 5 - Performing the record function

  • In the Live data function select the 'Record' button to record the Live Data of your vehicle at this time.
  • The PIDs list is saved in the Record mode based on the PIDs list you chose in the Live Data function.
  • Select the ‘Stop Record’ button to finish the record function and save the recorded data.
  • After selecting the ‘Stop Record’, a ‘Save Live Data’ popup shown as in the image has two options:
    • Select the ‘Yes, Save Live Data’ button to save the record which can be reviewed with the 'Play Back’ feature.
    • Select the ‘No, Erase Live Data’ button to finish the record function and go back to the Live Data Menu.

Step 6 – Playback the recorded data

  • From Live Data, select ‘Playback’ to view the record data.
  • The Playback function provides two types to view the record data: Continuous Playback and Frame by Frame
    • Continuous Playback displays the data record for each frame in a continuous manner, showing the entire record data automatically. Tap the ‘Play’ icon to start or stop the record.
    • Frame by Frame displays the data record for each frame by selecting the ‘Rewind’ and ‘Forward’ icon buttons, showing the entire record data manually.

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.
