Introduction
This brochure describes the checking of the Ecotronic system from the E 18 NVR engine with TECH 1 and Program Module OPEL/VAUXHALL 89-90 ECU. A description of the checking of Ecotronic without TECH 1 is available in the "Opel Ecotronic Combined Mixture and Ignition System" Checking Procedures, dated January 1989.
The Checking System
A checking concept has been developed which has pointed the way for the checking of electronic systems in vehicles.
Using TECH 80 and TECH 1, as well as universal checking adapters, checking cables and Electronic-Kit I, the electronics of all vehicles can be checked.
With TECH 1 and the appropriate Program Module, it is possible to read out streams of data from electronic control units via the Diagnostic Plug [X 13]. A precondition for this is the use of electronic systems with
· microprocessor techniques
· self-diagnosis
· serial data line
