Description
When the brake pedal is depressed, ASCD brake switch is turned OFF and stop lamp switch is turned ON.
ECM detects the state of the brake pedal by those two types of input (ON/OFF signal).
Refer to EC-68, "System Diagram" for the ASCD function.

Ignition signal
Description
The ignition signal from the ECM is sent to and amplified by the power
transistor. The power transistor turns
ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the
proper high voltage in the coil
secondary circuit.
