ASCD BRAKE SWITCH
DescriptionINFOID:0000000003858142
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 two kinds of input (ON/OFF signal).
Refer to EC-51, "
System Diagram" for the ASCD function.

Reference ValueINFOID:0000000003856868
VALUES ON THE DIAGNOSIS TOOL
Remarks:
l Specification data are reference values.
l Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show
the specification data in spite of the ignition timing not being adjusted to the specification data. This IGN TIM-
ING monitors the data calculated by the ECM according to the signals input from the camshaft position sensor
and other ignition timing related sensors.
