AUTOOL Diagnostic Scanners

AUTOOL diagnostic scanners

AUTOOL diagnostic products focus on the protocol and bench side of diagnosis rather than general code reading. Tools such as the MMT580 OBD II protocol detector and breakout box let you verify pin assignment, check power and ground at the diagnostic connector, and supply ECU power on the bench.

This is the equipment you reach for when a scan tool will not connect at all, and you need to establish whether the fault is in the vehicle wiring, the connector or the module.
