The Opel/Vauxhall Checking System
The Opel/Vauxhall checking system "TECHLINE" is based on a technical checking concept developed by Opel/Vauxhall for fault recognition and localisation in electronic vehicle systems.
Vehicle systems whose control units feature self-diagnosis and a serial data lead to the diagnostic plug can be checked with TECH 1 in conjunction with the relevant program module. Communication is possible not only from the control unit to TECH 1 (e.g. F2:TROUBLE CODES, F0:DATA LIST) but also in the opposite direction (e.g. F5:ACTUATOR TEST, F7:PROGRAMMING, F8:ECU CONTROL).
There is a detailed description of all the functions supported by TECH 1 in the TECH 1 Operating Instructions, which are supplied along with the Opel/Vauxhall Omega-B 1994 ECU program module.
Vehicle systems without self-diagnosis and serial data leads are also covered by the TECHLINE concept. Trouble-shooting starts here via the trouble-shooting table, on recognition of a malfunction.
The target of each check is rapid localisation of the fault (e.g. switch, lead, servo motor, control unit). The specified sequence for the individual test steps is an important element of the diagnosis concept and must therefore always be observed precisely. Deviations can lead to incorrect diagnosis.
