DTC P1720 VSSPFP:31036
DescriptionEBS018LQ
NOTE:
If DTC P1720 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
EC-132, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
ECM receives two vehicle speed sensor signals via CAN communication line. One is sent from ESP/TCS/ABS
control unit (models with ESP) or “ABS actuator and electric unit (control unit)”(models without ESP), and the
other is from TCM (Transmission control module). ECM uses these two signals for engine control.
CONSULT-II Reference Value in Data Monitor ModeEBS018LR
Specification data are reference values.
On Board Diagnosis LogicEBS018LS
The MI will not light up for this diagnosis.
DTC Confirmation ProcedureEBS018LT
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine.
4. Drive vehicle at a speed of 20 km/h (12 MPH) or more for at least 5 seconds without brake pedal depress-
ing.
5. If 1st trip DTC is detected, go to EC-379, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.

DTC P1805 BRAKE SWITCHPFP:25320
DescriptionEBS010U2
Brake switch signal is applied to the ECM through the stop lamp switch when the brake pedal is depressed.
This signal is used mainly to decrease the engine speed when the vehicle is driving.
CONSULT-II Reference Value in Data Monitor ModeEBS010U3
Specification data are reference values.
On Board Diagnosis LogicEBS010U4
The MI will not light up for this self-diagnosis.
FAIL-SAFE MODEEBS010U5
When the malfunction is detected, the ECM enters in fail-safe mode.
DTC Confirmation ProcedureEBS010U6
WITH CONSULT-II
1. Turn ignition switch ON.
2. Fully depress the brake pedal for at least 5 seconds.
3. Erase the DTC with CONSULT-II.
4. Select “DATA MONITOR” mode with CONSULT-II.
5. If 1st trip DTC is detected, go to EC-382, "

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.
