Endeavour ET3040 OBDII Break Out Box User Manual

Endeavour ET3040 OBDII Break Out Box

Product Information

The ET3040 OBDII Break Out Box is a diagnostic tool designed to change the automotive diagnostic OBD switch to signal judgment level transfer. It can connect with scan tools and determine if car communication is normal. Additionally, it can supply power to the car during battery replacement to prevent a loss of vehicle settings.

Features:

1. Test and find out the connection fault of OBD2 interface when using the tool.
2. Monitor OBD interface voltage and ground wire to display low voltage and diagnose faults.
3. Used for OBD interface signal jumping and quickly testing ifevery diagnostic stitch communication of OBD diagnostic interface is OK.
4. Save automotive data and prevent automotive data loss and electric device locking.

Product Usage Instructions

Actual Testing Instructions:
If the car diagnostic communication wire is NO. 15 and the diagnostic tool wire is NO. 7, the car cannot be tested normally. To solve this, connect the OBD adaptor to NO. 7 wire and NO. 15 wire. When testing NO. 7 and NO. 15, the LED light will turn on and flash, indicating a successful test.

Replace Car Storage Battery:
When replacing the car’s storage battery, the ET3040 OBDII Break Out Box can supply power to the car to prevent a loss of vehicle settings. Follow the manufacturer’s instructions for replacing the battery, ensuring that the OBDII Break Out Box is properly connected during the battery replacement process.

Introduction

Overview of Test Box

The OBDII Protocol Detector & Break Out Box is designed for changing automotive diagnostic OBD switch to signal judgment level transfer. It can connect with scan tools and judge whether car communication is normal. Also it can supply power to the car during battery replacement in order to prevent a loss of vehicle settings.

Function

Features of Test Box

1. Test and find out the connection fault of OBD2 interface when using the tool.
2. Monitor OBD interface voltage and ground wire so that it can display low voltage and fault diagnose stitch.
3. Used for OBD interface signal jumping and quickly test if every diagnostic stitch communication of OBD diagnostic interface is OK.
4. Save automotive data and prevent automotive data losing and electric device locking.

Usage

Actual testing instructions

1. In series connect OBD signal adaptor and car fault diagnostic tester. It supplies power normally if its storage battery voltage LED displays more than 10V and NO.16, NO4 or NO.5 LED light. It’s shortage of storage battery voltage if less than 10V. None of LED turning light means that there is something wrong with the diagnostic holder power supply, then check whether abnormal with the holder and storage battery voltage.
2. The communication signal LED will turn light during testing (Eg: NO. 7 wire signal). The testing of NO.7 pin is normal when LED flash, it means communicate normally.
3. The car diagnostic communication is NO. 15 wire but diagnostic tool is NO. 7 wire, it can’t test car in normal. OBD adaptor can connect NO.7 wire and NO.15 wire. When it test NO.7 and NO.15 LED light will turn on and flash. It can test as normal.

 Replace car storage battery

1. Connect the OBD signal adaptor and the car diagnostic holder, NO. 4 and NO.6 LED light,with 12V.
2. Supply power to NO.4 negative pin and NO.6 positive pin. Then the OBD adaptor can supply power to the car through diagnostic holder positive and negative, to prevent losing car data / radio settings.
3. Remove the car battery.
4. Switch off the power and OBD adaptor in order to finish battery changing.
