Perhaps the most celebrated feature of Diagnostic Tool V1.028b is Ghost Capture. When a system intermittently glitches (e.g., a PLC resets once every 8 hours), the tool enters a low-power ring buffer mode, continuously recording the last 10 minutes of bus traffic and power rail voltage. The moment a glitch is detected, it freezes and saves the pre- and post-event data. No more "it worked fine when I was watching."
Engineers can write simple Lua scripts to automate complex test routines:
-- Example: Cycle power and check boot-up handshake
power_cycle(3000) -- 3 second off, then on
wait_for_heartbeat(500, 2000) -- expect 500ms period, timeout 2s
assert(can_check_node(0x42), "ECU not responding")
log_result("Boot test passed at " .. timestamp())
These scripts can be saved, version-controlled, and deployed across multiple identical assets. Diagnostic Tool V1.028b

Exit code summary:
A Tier-1 supplier noticed that their electronic control unit (ECU) reset every 6 to 9 hours on the test track but never in the lab. Using Diagnostic Tool V1.028b in Ghost Capture mode, they discovered a 200mV droop on the 5V rail occurring exactly 14ms before every watchdog reset. The culprit: a shared ground path with the HVAC blower motor. The tool’s voltage trend graph made the culprit visible within two drive cycles.

Connect the tool to your CAN, I²C, SPI, or LIN bus, and you’ll see:
The development team has confirmed that Diagnostic Tool V1.028b will remain supported through at least 2027. However, work has begun on V1.029, which will add: These scripts can be saved, version-controlled, and deployed
Current users of V1.028b will receive a free upgrade.
