the temperature in the converter can rise above the admissible
limit and the converter will fail. So, special attention must be
paid to the operation of the fuel system and the ignition system.
Three-cylinder operation of the engine is prohibited even for a
short period of time.
fuel injection system with microprocessor-controlled fuel
supply and ignition (fig. 9.7)
To accomplish the Integrated Microprocessor-based Engine
Control System (IMECS) control unit self-diagnostics mode,
and to connect the engine control system automated external
diagnostics and programming devices, the data link connector
is installed under the hood on the front body panel (above the
engine).
The main switch power circuit, running from the battery, is
protected against ground short circuits with 10 A harness fuse.
At the same time, IMECS ignition circuit is protected against
