A DRB-III Scan Tool is an expensive device that, in conjunction with the electronics on a number of automobiles, may be able to diagnose a variety of problems that may be plaguing your vehicle.
Electronic Diagnostics
All cars produced after Jan. 1, 1996 have been required to utilize OBD-II (On-board Diagnostics) to electronically report vehicle problems upon being scanned. Different vehicle manufacturers require unique tools to be able to scan and diagnose error codes.
DRB-III
When associated with vehicles, DRB stands for Diagnostic Readout Box. The DRB-III Scan Tool is a device supported by Chrysler, Jeep and Dodge brand vehicles to interface with the car's electronics and interpret errors. As of January 2011, it is the newest incarnation of the device, with DRB and DRB-II preceding it.
Use
The DRB-III Scan Tool is able to read OBD-II error codes, including those for various engine parts and parts focused on emissions. Using a DRB-III Scan Tool when a "Check Engine" light is on may prevent your vehicle from enduring further damage. As of January 2011, DRB-III Scan Tools may cost approximately $6,000 to $7,000.
