A professional advanced breakout box for invehicle diagnostics / bench ECU testing, supporting both 12V / 24V systems.

More than just a basic breakout box - it exposes every OBD-II pin, monitors live voltages (true RMS), provides optional CAN termination, and supports safe, fast hookup of other diagnostic devices.

Key features:

• Universal compatibility: Works seamlessly with both 12V and 24V OBDII systems.
• VRMS Voltage Monitoring In Real Time: LCD displays true RMS voltage on all 16 OBDII pins. Visual feedback shows dynamic signals (green background), and immediately alerts for power / ground issues (pins 4 / 5 / 16)
• Built-In CAN Termination Switch: Applies a 120 resistance across the CAN pair to compensate for missing termination during single-ECU or small bench networks, improving signal integrity and reducing reflections.
• Voltage Protection & Alarm System: Features automatic audible alarms for high/low voltage deviations and reverse polarity protection. Supports a maximum load current of 2A.

This test performs leak down tests which can be more accurate than normal compression tests.

Leak down tests can be used to detect various engine faults including leakage past rings, head gaskets, intake / exhaust valves etc.

• Requires air source of 70-160PSI, as the unit will pressurise system to 60PSI.
• Spark plus thread hoses: 10, 12, 14mm | regulator & o-rings

This kit contains a special cap, and gauge in order to test oil pressure on a range of BMW engines.

• Engines: N20 | N46 | N55
• OEM equiv: 119250

Easy to read 2-1/2" diameter gauge features colour coded quadruple calibrations. 6" heavy duty stem with universal rubber cone adaptor fits all plug holes. Convenient pressure holding side release valve. Provides an accurate reading on high performance engines.

• 0-300 PSI | 21kg/cm | 21 Bar | 2100kPA
• 13" durable rubber hose with 14mm | 18mm adaptors.

This cylinder leakage kit can diagnose a range of engine faults including blown head gaskets, cylinder head cracks, and worn piston rings / valves.

The twin gauge manifolds shows percentage of cylinder leakage, and cylinder pressure. Suitable for use on petrol engines with 10 | 12 | 14mm spark plugs.

For deeply recessed spark plugs, a long reach compression test adaptor may be required.

• Suitable for use with 10mm / 12mm / 14mm spark plugs.
• Readings: cylinder leakage / cylinder pressure (psi / bar)

Comprehensive set with adaptors to suit most common Asian / European / US vehicles. These connectors are not interchangeable with the ET7191 compression test kit.

• Normal operating range: 750PSI
• Gauge: 0-1,000 PSI

Tests return flow pressure from Bosch | Delphi | Siemens common rail injectors. Suitable for testing Piezo pass / fail statement.

• Gauges: 1-3 Bar & 1-15 Bar.
• Transparent body to check for air pockets / diesel fuel condition.
