The Autodiagnos Multi‑Tester Pro is a handheld serial diagnostic tool used for fault finding on automotive Electronic Control Units (ECUs). Common failure points in this class of equipment include worn or corroded connectors, degraded internal power supply components, and firmware corruption that can cause communication timeouts. Begin troubleshooting by verifying the unit’s battery voltage and ensuring the power‑on LED functions; next check all cable connections for proper seating and inspect the serial port for physical damage; finally review any stored error codes or diagnostic logs for patterns such as “ECU not responding” or “communication timeout.”[oss-gpt-20b] |
