Introduction
This brochure describes the checking of the Anti - lock Brake System ABS - 2 SH with TECH 1 and the newly developed Program Module Opel / Vauxhall Omega - B 1994 ECU.
The Checking System
A checking concept has been developed which has pointed the way for the diagnosis of electronic systems in vehicles.
The electronics of all vehicles can be checked using TECH 80, TECH 1, Universal Checking Adapters, Checking Leads and Electronic - Kit 1.
With TECH 1 and the appropriate Program Module, it is possible to read out streams of data from electronic control units via diagnostic plugs. A precondition for this is the use of electronic systems with
- microprocessor techniques - self - diagnosis - serial data line
General Instructions / Safety Measures
Readout of data using TECH 1 takes place with ignition ON and / or with engine operating. Trouble codes are deleted by pressing the "F4" key. Important: During diagnosis using TECH 1, the ABS is not functional (except in F3: SNAPSHOT MODE or F6: WHEEL SENSORS).
Safety Measures:
- Allow at least 20 seconds after switching off engine before disconnecting / reconnecting plugs of electric / electronic modules. - Never disconnect battery from vehicle electrical system with engine running. - During electric welding work, always disconnect the plug from the control unit. - At temperatures above +80° C / +176° F (drying oven), control units must be removed. - Before charging or quick - charging, disconnect the battery from the vehicle electrical system. - Never use the quick - charger for starting. - Caution when touching voltage - bearing parts of the ignition system. - Use only high - resistance voltage tester for checking.
IMPORTANT: After disconnecting the battery, volatile memories must be reprogrammed. In the case of radio coding and radio station programming, the customer should be informed about the decoding and deleted station programming.
