DTC 0804 ECM 11ZD30DDTi
EC-208
http://vnx.su/

Description
The stop lamp switch is installed to brake pedal bracket. The switch
senses brake pedal position and sends an ON-OFF signal 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.
