LUTIFIX OBD2 Breakout Box 16-Pin with 17.7 in Cable — 4mm Jacks for Multimeter & CAN/K‑Line Diagnostics

The LUTIFIX OBD2 Breakout Box is a 16-pin OBDII test interface that exposes power, ground and communication lines so you can safely monitor, power and troubleshoot vehicle data buses.

This compact diagnostic accessory turns a vehicle’s OBDII connector into an accessible test station. It gives technicians and advanced DIYers direct access to all 16 pins, built-in 4mm jacks for meters and scopes, a flexible 17.7-inch cable and a 5 ft alligator power lead. Designed for multi-device connectivity, the unit helps you observe CAN, K-line, L-line and PWM signals, feed regulated power to an ECU during battery swaps, and isolate faults without repeatedly plugging and unplugging connectors.

How does this breakout box make vehicle diagnostics easier?

The LUTIFIX breakout box converts the vehicle’s OBDII port into a permanent test point, reducing connector wear and simplifying repeated measurements. It exposes each pin clearly and provides banana-plug friendly jacks to attach meters or oscilloscopes without improvising adapters.

• Full 16-pin OBDII layout mapped to labeled terminals for fast identification
• Built-in 4mm jacks for secure multimeter and oscilloscope connections
• 17.7-inch flexible TPU cable to reach cramped engine bays or underdash areas
• Universal wire jumpers allow simultaneous connection of multiple scan tools

Can it supply power and help with ECU or battery tasks?

Yes — when tied to an appropriate external DC supply, the breakout box can feed power back into the vehicle’s data link so you can power an ECU or perform battery maintenance without relying solely on the vehicle battery. Follow the unit’s power limits and connection guidelines to avoid damage.

• Accepts DC 8V–30V input to supply the vehicle’s onboard systems within limits
• Includes a 5 ft alligator clip DC lead for temporary bench or battery hookup
• Warning: do not exceed 1 amp load through the breakout box connection
• Ideal for ECU bench tests and short-term power during battery replacement

Which communication protocols and testing scenarios are supported?

The gadget supports common OBDII communications so you can monitor or inject signals across multiple in-vehicle networks. It’s suitable for tracing faults, confirming bus activity, and comparing protocol behavior across tools.

• Compatible with CAN bus, K-line, L-line and PWM protocol monitoring
• Allows simultaneous connection of scan tools, scope probes and multimeters
• Universal wire jumpers enable flexible wiring and parallel diagnostics
• 4mm banana jacks provide reliable measurement points for waveform capture

What safety and warranty considerations should I know before using it?

Designed for professional and informed hobby use, the breakout box requires careful handling to avoid shorts or overcurrent. LUTIFIX provides a three-year parts replacement policy for non-human damage and responsive customer support to help with product issues.

• Do not connect a load above 1 amp through the breakout box
• Avoid directly shorting pins 4, 5 or 16 to prevent damage
• 3-year limited parts replacement warranty for manufacturing faults
• Contact LUTIFIX support for troubleshooting and replacement parts

Who is this for: The LUTIFIX OBD2 Breakout Box is built for professional mechanics, automotive electricians and experienced DIYers who need clear, repeatable access to an OBDII data link. If you regularly perform bus diagnostics, bench-test ECUs, capture waveforms, or run multiple scan tools at once, this breakout box saves time and reduces connector wear while giving reliable measurement points for advanced troubleshooting.
