This is a testing platform for OBDII protocol detection and communication diagnostics. It converts the vehicle's OBD2 interface into a 6-pin configuration for signal detection and voltage level conversion. Compatible with most diagnostic tools, it helps determine if the vehicle’s communication system is functioning properly. Provides power supply during battery replacement to help prevent loss of ECU memory, system locks, remote key failure, or warning light activation. Features: - Tests for faults in the OBDII interface - Battery replacement support tool - Voltage display for OBDII systems Usage: 1. Connect the OBDII Break Out Box to the vehicle’s OBDII port. 2. The device displays the system voltage. 3. Connect a diagnostic tool; when communication occurs, the corresponding protocol LED illuminates or flashes. CAN protocol detection shows maximum brightness. Functions: - Displays test voltage for cars or trucks - Shows communicating pin number - Acts as an extension for the OBD Diagnostic Link Connector - Enables pin short-circuit testing - Detects isolated circuit issues - Serves as a power extension for small DC devices requiring external power (up to 1.2 amps) - Allows circuit testing using a multimeter or oscilloscope - Verifies Power (Pin 16), Chassis Ground (Pin 4), and Signal Ground (Pin 5) - Helps preserve ECU data during battery replacement Note: Product design may vary slightly between batches. These variations may include color or minor structural differences, but do not affect functionality. Color: As shown in photos Material: ABS Package Includes: 1 x Car OBD Break Out Box Note: Other items not included. Lighting and display settings may cause slight color differences between images and actual product. Measurement tolerance: +/- 1-3 cm.
