These later versions included a better instruction manual some had instructional video tapes, Technical Service Bulletin manuals, and PROM ID manuals.

#Aldl scan tool update
The later versions 2000, 4000, 4000E and the Enhanced obd scan tools were equipped with the ability to update or add functions via a software cartridge, different cables, and cable inserts. The Monitor 85 can service vehicles until about 1988, but you must ‘lie to the tool’ or purposely misidentify the vehicle and engine. All require the mechanic to input the information to properly identify the vehicle. Monitor 85 included an adapter to access the 1980 and early 1981 5 pin ALDL connector, a small operations instruction manual, and 3 specifications cards. This tool had the cables hard wired and the software was permanently programmed into the tool. This version had most of the sensors / switches (PIDs) cross referenced on the face of the tool. The early version was called Monitor 85, which was introduced with 1982 model year GM vehicles. Later OTC added the capabilities to scan Japanese made vehicles.
They were made specifically for the domestic vehicles of the time GM, Ford, and Chrysler. Later versions include a rubber protective wrapper to protect the units more. They were built for the rough work environment of the service areas. Development ceased in 2002 but the later model scan tools have the capability to perform OBD2 diagnostics until the 2006 model year on some vehicle brands. Development continued by OTC until GM started switching the standard corporate protocol to Controller Area Network (CAN). The retail version and the dealer versions differ only by cosmetics. It was GM’s dealer essential scan tool until 1995 when the Vetronix unit replaced it. This scan tool series was the dealer essential (required) tool for General Motors and Ford during OBD I. All of the OTC monitor obd scan tools are what we now refer to as enhanced or manufacturer level data tools.
