The Opel Checking System
The "TECHLINE SYSTEM", a technical testing concept developed by Opel, has pointed the way for the checking of electronic systems in vehicles.
At the heart of this system are TECH 1 and TECH 80. In conjunction with the respective Checking Cables and Electronic-Kit I, all OPEL/VAUXHALL vehicles, even those of the new generation, can be checked with the most modern electronic equipment.
With TECH 1, it is possible to read out streams of data from electronic control units. A precondition for this is the use of electronic systems with
· microprocessor techniques · self-diagnosis · serial data line
Before the start of diagnosis, the program module corresponding to the Model Year of the vehicle is inserted and then TECH 1 is connected to the diagnostic plug in the vehicle. The streams of data captured on TECH 1 are presented on a 4-line, 16-character display.
The current actual values displayed are compared with the nominal values from the data list. Where there are deviations from the relevant nominal values, a trouble-shooting program is available, so that the user can make a clear diagnosis. The TECH 1 checking concept means rapid and accurate trouble-shooting.
There is a special mode, the "Snapshot Mode", that can be used during a test drive to localize misfiring in the C 12 NZ/C 14 NZ engine caused by loose connections - see also TECH 1 Operating Instructions.
