Autel MaxiSYS Oscilloscope Accessory Kit

Autel MaxiSYS Oscilloscope Accessory Kit (MSOAK)

The Autel MSOAK MaxiSYS Oscilloscope Accessory Kit is an add-on accessory package that expands the measurement capability of the MaxiFlash VCMI (included with the MSUltra and MS919) and the MP408 4-channel oscilloscope. If you are already running one of these tools with oscilloscope capability, the MSOAK adds professional-grade current clamps, a coil-on-plug probe, and HT leads to your kit — the accessories needed for real-world engine electrical diagnosis on most common failure scenarios.

Compatibility

• MaxiFlash VCMI — included with Autel MSUltra and MS919
• MP408 — Autel 4-channel oscilloscope (sold separately)

This kit is not a standalone tool and requires one of the above devices to operate.

What Is Included

• 65A AC/DC Current Clamp — measure current on low-amperage circuits including sensors, injectors, and small motors without breaking the circuit
• 650A AC/DC Current Clamp — measure high-amperage circuits including starter current draw, alternator output, and battery charge/discharge rates
• Coil-on-Plug Probe — inductive pickup for testing coil-on-plug ignition systems without removing the coil; essential for misfire diagnosis on modern vehicles
• HT Extension Lead x2 — high-tension extension leads for secondary ignition testing
• Battery Clip x2 — secure connection clips for stable test point connections
• Blow-molded carrying case — keeps accessories organized and protected between uses
• 1-year limited warranty

Why These Accessories Matter

Oscilloscope work in an automotive shop breaks down into a handful of common test categories, and the MSOAK covers them:

• Starter/charging diagnosis — the 650A clamp lets you capture starter current ramp patterns and alternator output waveforms without any circuit modification
• Injector testing — the 65A clamp captures injector current waveforms to verify pintle lift, driver signal, and injector balance without unplugging connectors
• COP ignition diagnosis — the coil-on-plug probe lets you check secondary ignition on individual cylinders without pulling coils or using a timing light
• General circuit testing — battery clips and HT leads provide stable connections for sensor signal testing, actuator testing, and general waveform captures

Practical Shop Use

Shops that invested in the MSUltra or MS919 for the built-in VCMI oscilloscope typically find that the base VCMI leads cover the basics but lack the current clamp capability needed for the diagnostic jobs that actually come through the door. The 65A and 650A clamps are the two accessories that get used on almost every electrical job. The COP probe is indispensable on modern vehicles where coil-on-plug ignition is nearly universal.
