Component Function Check

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 System Description .

1. CHECK ASCD BRAKE SWITCH FUNCTION 

   With CONSULT

   1. Turn ignition switch ON.
   2. Select "BRAKE SW1" in "DATA MONITOR" mode with CONSULT.
   3. Check "BRAKE SW1" indication under the following conditions.

      Monitor item	Condition		Indication
      BRAKE SW1	Brake pedal (A/T or M/T models and synchrorev match mode) Brake pedal and clutch pedal (M/T models without synchrorev match mode)	Slightly depressed	OFF
