Introduction
This brochure was conceived to appear simultaneously with the availability of the new TECH 1 program module OPEL/VAUXHALL RV/LCV 92-93 ECU, and to provide workshop personnel with the latest information necessary for the most advantageous use of the new program module in troubleshooting with the 2.3L (4ZD1) engine of the Campo.
The new TECH 1 program module OPEL/VAUXHALL RV/LCV 92-93 ECU is the first module to combine all systems developed to date by Opel/Vauxhall for checking with TECH 1 in the vehicles Frontera, Monterey und Campo. Therefore it is now possible to perform diagnostic work on these systems with only one program module.
By using these checking instructions, the attached engine circuit diagram, the corresponding service manual and the operating instructions for TECH 1, it is now possible to save a considerable amount of time in diagnosis and repair work.
