Remove guesswork from modern vehicle diagnostics by putting every OBDII circuit at your fingertips. This professional breakout box gives technicians instant access to every OBDII circuit for faster fault finding, ECU testing, and network diagnostics. Whether you're diagnosing communication faults, testing CAN bus systems, performing ECU bench testing, or verifying vehicle power and ground circuits, the ET3142 provides the visibility and control that standard scan tools simply can't offer.

Featuring a built-in LCD display with real-time True RMS voltage monitoring across all 16 OBD-II pins, the ET3142 allows technicians to instantly identify power supply issues, ground faults, CAN communication activity, and wiring problems without repeatedly probing connectors. Dynamic signal detection, audible voltage alarms, and ground status indicators help reduce diagnostic time and improve accuracy.

The integrated 120 CAN termination switches make the ET3142 an invaluable tool for ECU bench testing and module diagnostics. By providing proper CAN network termination, technicians can test modules off the vehicle with improved signal integrity and confidence. Compatible with both 12V and 24V systems, it is suitable for passenger vehicles, trucks, buses, and commercial equipment.

• Real Time VRMS Voltage Monitoring - displays real time True RMS voltage on all 16 OBDII pins
• Built In CAN Termination for Bench & ECU Testing - an onboard 120 ohm CAN termination switch is ideal for situations where termination is missing such as single ECU or small bench networks.
• Intelligent Voltage Protection & Audible Alarm System - reverse polarity protection, automatic alarms for over voltage and under voltage conditions, and support for currents up to 2A, ensures that both the vehicle and diagnostic tools stay protected during testing.
