Innova SD35 SD-Advisor: Viewing Live Data

Purpose

To guide you on how to view live data using the SD35 SD-Advisor Tablet Scan Tool.

Introduction

The Tablet 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 Tablet for each sensor, actuator, switch, etc. is called Parameter Identification Data (PID).

Each PID (sensor, actuator switch, status, etc.) has a set of operating characteristics and features (parameters) that serve to identify it. The Tablet displays this information for each sensor, actuator, switch, or status that is supported by the vehicle under test.

Procedure

Step 1 - Connect the Innova SD35 SD-Advisor Tablet Scan Tool to the vehicle and select the 'OBD2 Diagnostics' function.

• First, connect the Innova SD35 SD-Advisor Tablet Scan Tool to your vehicle via the Diagnostic Link Connector (DLC) to retrieve the vehicle's information.

Step 2- From the OBD2 Menu, select the 'Live Data' function.

• From the OBD2 Menu, select 'Live Data - $01', then press the OK button.
• If the Scan 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.
  • Press Relink to continue.

Step 3 - View the Real-time Live Data (PID) information.

• Real-time Live Data (PID) information supported by the vehicle under test will be displayed.
• The values for the various PIDs displayed may change as the vehicle’s operating conditions change.
• The Graph function button will stay inactive if the selected PID does not report a numerical value.
• 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 UP and DOWN, as necessary, to view available PID data.
• If communication with the vehicle is lost while viewing Live Data, an advisory message is displayed.

Step 4 - View the expanded definition and description for the currently selected PID.

• Press OK to view the expanded definition and description for the currently selected PID.
• Press the Back button to return to the Live Data – $01 screen after you have finished viewing.

Step 5 - Select Graph to view the currently selected PID in “graph” mode.

• Select Graph and press OK to view the currently selected PID in “graph” mode.
• Select Merge Graph to view more PID results on one graph.
• Select Multi Graph to view more Graphs on one screen.
• Troubleshoot any diagnostic issues by referencing your vehicle’s repair manual to view and/or compare Live Data (PID) information displayed on the Tablet Scan Tool against recommended vehicle specifications.
