DescriptionNJEC0654The vehicle speed sensor is installed in the transaxle. It contains a
pulse generator which provides a vehicle speed signal to the
speedometer. The speedometer then sends a signal to the ECM.
ECM Terminals and Reference ValueNJEC0655Specification 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.

Overall Function CheckNJEC0657Use this procedure to check the overall function of the vehicle
speed sensor circuit. During this check, a DTC might not be con-
firmed.
WITH CONSULT-IINJEC0657S011) Lift up the vehicle.
2) Start engine.
3) Read vehicle speed sensor signal in ªDATA MONITORº mode
with CONSULT-II.
The vehicle speed on CONSULT-II should be able to

able gear position.
4) If NG, go to ªDiagnostic Procedureº, EC-705.
WITHOUT CONSULT-IINJEC0657S021) Lift up the vehicle.
2) Start engine.
3) Read the voltage signal for the vehicle speed sensor with an
oscilloscope. Refer to ªECM Terminals and Reference Valueº,
EC-701.
4) Verify that the oscilloscope screen shows the signal wave as
shown at ªECM Terminals and Reference Valueº, EC-701.
5) If NG, go to ªDiagnostic Procedureº, EC-705.

DescriptionNJEC0738The 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 ValueNJEC0739Specification 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.
