Fuel Shutoff

Fuel Shutoff





Load signal (tq), fuel shut-off

In the case of fuel shut-off (accelerator release), the signal from the LH control module to the DI/APC control module is interrupted. The control module then retards the ignition and the return will be smoother.

The signal is sent from LH control module pin 25 (pin 24 for LH 2.2) to DI/APC control module pin 36 or EZK control module pin 8.
