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 result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic ProcedureEBS010TE
1. INSPECTION START
Do you have CONSULT-II?
Ye s o r N o
Ye s > > G O T O 2 .
No >> GO TO 4.
2. CHECK COOLING FAN LOW SPEED OPERATION
With CONSULT-II
1. Turn ignition switch ON.
2. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II and touch “LOW” on the CONSULT-II screen.
3. Make sure that cooling fans-1 and -2 operates at low speed.
OK or NG
OK >> GO TO 3.
NG >> Check cooling fan low speed control circuit. (Go to EC-
359, "PROCEDURE A" .)
3. CHECK COOLING FAN HIGH SPEED OPERATION
With CONSULT-II
1. Touch “HIGH”on the CONSULT-II screen.
2. Make sure that cooling fan-2 operate at higher speed than low
speed.
OK or NG
OK >> GO TO 6.
NG >> Check cooling fan high speed control circuit. (Go to EC-
361, "PROCEDURE B" .)

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for 1 second.
4. If DTC is detected, go to EC-370, "

Component DescriptionEBS010TV
When the shift lever position is P or N (A/T), Neutral (M/T), park/neutral position (PNP) switch is ON.
ECM detects the position because the continuity of the line (the ON signal) exists.

On Board Diagnosis LogicEBS010TX
DTC Confirmation ProcedureEBS010TY
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 “P/N POSI SW” in “DATA MONITOR” mode with CON-
SULT-II. Then check the “P/N POSI SW” signal under the follow-
ing conditions.
If NG, go to EC-376, "
Diagnostic Procedure" .
If OK, go to following step.
3. Select “DATA MONITOR” mode with CONSULT-II.
4. Start engine and warm it up to normal operating temperature.
5. Maintain the following conditions for at least 60 consecutive sec-
onds.
6. If 1st trip DTC is detected, go to EC-376, "

DTC P1720 VSS

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, "
