This new addition to our Foxwell range combines an OBDII code reader, with a 12V battery tester in one convenient tool.

The OBDII code reader is compatible with all OBDII compliant vehicles, and reads / clears engine codes and turns off the Check Engine light. Plus the code reader has a built in trouble code database, and offers Automatic VIN recognition.

The 12V battery tester analyses the state of health on all common automotive batteries including AGM / Flooded / Gel batteries. Test reports can be printed via a PC.

• 100 - 1,100CCA battery range
• Lifetime free updates

The ET8040 disconnect kit is designed to assist with releasing electronic connectors on Knorr Bremse EBS modules. This kit comprises 3 tools for separating 2, 4, 6 & 12 pole electrical connectors on the trailer module, as well as a tool for loosening the bayonet nut on the power supply connection.

• Ideal for tight working areas on HGV trailers
• Manufactured from steel with vinyl dipped handles for improved comfort / grip

The ET3142 is a professional-grade breakout box designed for advanced in-vehicle diagnostics and bench-top ECU testing on both 12V and 24V systems. It exposes every OBDII pin for full signal access, monitors live circuit voltages with true-RMS accuracy, and includes selectable CAN termination for controlled network testing. Its secure, high-speed interface allows safe integration of scopes, scan tools, and other diagnostic equipment, making it an essential tool for precise fault-finding, signal analysis, and ECU development work.

• Real Time VRMS Voltage Monitoring on All OBDII Pins - the integrated LCD displays true RMS voltage across all 16 pins, delivering accurate diagnostics even on fluctuating or noisy circuits. Green background highlights active dynamic signals, while immediate alerts help identify power or ground issues on critical pins (4, 5, and 16).
• 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. This helps improve signal integrity, reduce line reflections, and stabilise communication during advanced diagnostic work.
• 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.

An advanced CANbus circuit tester compatible with both 12V and 24V systems.

Provides a live display of present communicating signals, and can display the voltage of each pin without having to use a multimeter.

Essential for checking ground / voltage on all OBDII pins prior to connecting a scan tool / flashing ECU. If your scan tool cannot communicate, it could simply be a fault with the OBD connector.

• Connect inline with scan tools, Or use with a multimeter / oscilloscope.
• Quickly diagnose CAN faults.
• Monitor battery voltage at the OBD port.
• A great way to log pin voltage data when used with our ET2504 multimeter.

• 14 Pin Benz connector

• 20 Pin Isuzu connector

• 3 Pin Isuzu connector

• 30 Pin Iveco connector
