The Opel Checking System
The "Opel Checking System", a technical testing concept developed by Opel, has pointed the way for the checking of electronic systems in vehicles.
At the heart of the Opel Checking System are TECH 1 and the Opel Tester. Together with the Universal Checking Adapter, the relevant checking cables and Electronic Kit I, all Opel vehicles of the new generation can be checked using the most modern electronic methods.
Since only electronic components are checked, only statements about electrical, electronic components can be made when checking with KM-640 and/or TECH 1.
A new phase in Opel diagnosis has been introduced with TECH 1. With this Hand Tester it is possible to read out streams of data from electronic systems. A precondition for this is the use of electronic systems with
· Microprocessor techniques · Self-diagnosis · Serial data line
TECH 1 is connected via the diagnostic plug in the vehicle. TECH 1 is a hand tester, constructed using module techniques. This concept ensures that modern electronic systems can be checked now and in the future. 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.
