Innova SDS43 SDS-Inspector: Reading and Erasing the OEM Trouble Codes

Purpose

To guide you on how to read and clear Original Equipment Manufacturer (OEM) Trouble Codes on the SDS43 SDS-Inspector Tablet Scan Tool.

Introduction

OEM Trouble Codes are unique to each vehicle manufacturer and are created by the automaker to diagnose issues within the vehicle's systems. These codes serve the purpose of diagnosing and fixing specific problems in the vehicle and are often exclusive to a particular manufacturer. If a code is stored, the Malfunction Indicator Light (MIL) on the dashboard lights up to indicate that a problem requires attention. A technician can identify the source of a system fault in the vehicle and carry out the required repairs by reading the codes.

This article demonstrates how to read and erase OEM Trouble Codes on a 2015 Chevrolet Equinox L4, 2.4L (VIN 8th = K) using the Innova SDS43 SDS-Inspector Tablet Scan Tool.

Procedure

Step 1 - Connect Innova SDS43 SDS-Inspector Tablet Scan Tool to the vehicle and select 'OEM Diagnostics' function

First, connect the Innova SDS43 SDS-Inspector Tablet Scan Tool to your vehicle via the Diagnostic Link Connector (DLC) to retrieve the vehicle's information, such as VIN and On-Board Diagnostic (OBD2) information.
There are two options to access 'OEM Diagnostics':
- Option 1 (AutoLink function is OFF): From the Home Screen, select 'OEM Diagnostics' section and press the OK button.
- Option 2 (AutoLink function is ON): From the 'OBD2 Control Display' screen, press 'Home' button, after that select the 'OEM Diagnostics' section.

Step 2 – Read OEM Diagnostic Trouble Codes (DTCs)

The Scan Tool lists four common systems on vehicles that users can quickly access to read DTCs. There are:
- Engine Control Module
- Transmission Control Module
- Anti-Lock Brake Control Module
- Supplemental Restraint System Control Module (Air Bag)
'OEM Diagnostics' function also supports the 'Scan All Systems' feature to scan all the systems in the vehicle.
Or select a system that is separated into three groups (Powertrain, Body, Chassis) as shown in the image you want to read DTCs.
Select ‘Read DTCs’ item to read the DTCs that ECU saved. The system menu provides you more options such as: Read DTCs, Erase DTCs, Live Data, Active Test and ECU Information.

Step 3 - View the result and check DTCs in the system

The Scan Tool displays the OEM diagnostic codes for the selected system, including the status and definition of the DTCs. The definition and status of DTCs may vary among different makes and models of vehicles.
The DTC status indicates the level of severity of the problem, providing technicians with insights into the issue, thereby improving their ability to diagnose and repair the vehicle in a more efficient manner.

Step 4 - Repair the issue and erase the DTCs

Once you have resolved all the DTCs in the vehicle, it is time to erase the codes and turn off the Malfunction Indicator Light (MIL) or warning light located on the dashboard of your vehicle.
You can select the ‘Erase DTCs’ item on the DTC result screen or go back to the System Menu and select the ‘Erase DTCs’ to erase the codes.
The process of clearing DTCs will be carried out by the Scan Tool. After completion, the Scan Tool will automatically conduct another scan of all systems to confirm that there are no remaining DTCs in the vehicle, guaranteeing that the problem has been completely resolved.

Summary

The use of a Scan Tool for diagnosing and fixing faults greatly simplifies the process in the current automotive industry. The method outlined is relevant for the 'Reading and Clearing OEM Trouble Codes' function on a 2015 Chevrolet Equinox L4, 2.4L (VIN 8th = K) utilizing the Innova SDS43 SDS-Inspector Tablet Scan Tool.
