DTC P1715 INPUT SPEED SENSOR (T
URBINE REVOLUTION SENSOR)
DescriptionINFOID:0000000001326352
ECM receives turbine revolution sensor signal from TCM through CAN communication line. ECM uses this
signal for engine control.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001326353
Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001326354
NOTE:
If DTC P1715 is displayed with DTC U1000 or U 1001 first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-146
.
 If DTC P1715 is displayed with DTC U1010, first pe rform the trouble diagnosis for DTC U1010. Refer
to EC-148
.
 If DTC P1715 is displayed with DT C P0605, first perform the trouble diagnosis for DTC P0605. Refer
to EC-422
.
 If DTC P1715 is displayed with DT C P0335, first perform the trouble diagnosis for DTC P0335. Refer
to EC-319
.
 If DTC P1715 is displayed with DTC P0340 or P 0345 first perform the trouble diagnosis for DTC
P0340 or P0345. Refer to EC-324
.
The MIL will not lights up for this self-diagnosis.

Therefore, when electrical controlled throttle and part
of ECM related diagnoses are continuously detected as
NG for 5 trips, ECM warns the driver that engine c ontrol system malfunctions and MIL circuit is open by means
of operating fail-safe function.
The fail-safe function also operates when above diagnos es except MIL circuit are detected and demands the
driver to repair the malfunction.

DTC U1000, U1001 CAN COMMUNICATION LINE
DTC U1000, U1001 CAN COMMUNICATION LINE
DescriptionINFOID:0000000001326545
CAN (Controller Area Network) is a serial communication
line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
On Board Diagn osis LogicINFOID:0000000001326546
*1: This self-diagnosis has the one trip detection logic.
*2: The MIL will not light up for this diagnosis.

DTC Confirmation ProcedureINFOID:0000000001326547
1. Turn ignition switch ON and wait at least 3 seconds.
2. Check 1st trip DTC.
3. If 1st trip DTC is detected, go to EC-725, "
