ECU Interface
The FETK-S2.1 is connected via connectors CON1 and CON2 to the ECU with
two adapter cables (refer to Fig. 4-2 on page 20). The pin definition depends on
the application and the microcontroller type. In general the ECU interface con-
sists of
• 1 ECU voltage line, which is not used for FETK power supply, but only for
detection of the ECU status, therefore the power consumption on this
line is negligible (refer to chapter 4.4 on page 22)
• 1 Reset line which allows the FETK to control the system reset of the
ECU
• 1 Reset line which allows the FETK to monitor the system reset of the
ECU
• 5 Debug line interfaces for the communication between the FETK-S2.1
and the microcontroller
• 1 Watchdog disable line
• 1 ground line
