DTC 0804 ECM 11YD25DDTi
EC-3584

Description
The stop lamp switch is installed to brake pedal bracket. The
switch senses brake pedal position and sends an ON-OFF sig-
nal to the ECM. The ECM uses the signal to control the fuel
injection control system.
ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.
