New command code system

New command code system

With the new EPROM that has been developed for the ISAT for model year 1994 cars, a completely new system of command codes has been introduced.

To obtain a readout or activate signals and functions, a three-digit code has previously been used. This has been superseded with effect from M94 by a system in which clear text messages under a number of menu choices make it easy to select the desired command directly from the keyboard.

The structure of the TCS system's command menu will be evident from the following schematic diagram.

Here we see that there are seven main menus, four of which have a varying number of commands or functions.

These are:


• OBTAIN READOUTS

• ACTIVATE

• READ SYSTEM INFO

• PROGRAM
