DTC P0500 VEHICLE SPEED SENYD22DDTI
Diagnostic Procedure
EC-1176

SEF751Z
DescriptionNLEC0738The 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 ValueNLEC0739Specification 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 result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
