Diagnostic Procedure
ECS004S8
1.CHECK DTC WITH ECM
Perform diagnostic test mode II (self-diagnostic results) for engine control.
Refer to EC-´´, “Malfunction Indicator Lamp (MIL)”.
OK or NG
OK (With CONSULT-II)>>GO TO 2
OK (Without CONSULT-II)>>GO TO 3
NG >> Check throttle position sensor circuit for engine control. Refer toEC-154, "
DTC P0121 APP SEN-
SOR".
2.CHECK INPUT SIGNAL (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “THRTL POS SEN”.
OK or NG
OK >> GO TO 4
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit. (Main
harness)

Wi th ou t C O N S U LT-I I
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 41 and 42 while accelerator pedal is depressed slowly.
(Voltage rises gradually in response to throttle position)
OK or NG
OK >> GOTO4
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit. (Main
harness)
4.CHECK DTC
Perform Diagnostic Trouble Code (DTC) confirmation procedure,AT-204, "
DIAGNOSTIC TROUBLE CODE
(DTC) CONFIRMATION PROCEDURE".
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Vo l ta g e :
Fully-closed throttle valve : Approximately 0.5V
Fully-open throttle valve : Approximately 4V

DTC P1760 OVERRUN CLUTCH SOLENOID VALVE
DTCP1760OVERRUNCLUTCHSOLENOIDVALVE
PFP:31940
DescriptionECS004S9
The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the inhibitor switch, overdrive control
switch, vehicle speed and throttle position sensors. The overrun
clutch operation will then be controlled.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting the
next test.
TESTING CONDITION:
Always drive vehicle on a level road to improve accuracy of
test.
After the repair, perform the following procedure to confirm the mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
2. Start engine.
3. Acceleratevehicletoaspeedofmorethan10km/h(6MPH)
with “D” position (OD “ON”).
4. Release accelerator pedal completely with “D” position (OD “OFF”).
With GST
Follow the procedure “With CONSULT-II”.

Diagnostic ProcedureECS004SB
1.CHECK VALVE RESISTANCE
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminal 3 and ground.
OK or NG
OK >> GO TO 2
NG >> 1. Remove control valve assembly. Refer toAT-454,
"REMOVAL".
2. Check the following items:
–Overrun clutch solenoid valve
Refer to “Component Inspection”,AT-212, "
Compo-
nent Inspection".
–Harness of terminal cord assembly for short or open
2.CHECK POWER SOURCE CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check continuity between terminal 3 and TCM harness connector terminal 20.
If OK, check harness for short to ground and short to power.

DTC U1000 CAN COMMUNICATION LINEPFP:31940
DescriptionECS004SD
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 speed and excellent error detection ability. MaDiag-
nosticny electonic control units are equipped onto a vehicle, and each control unit shares information and links
with oter control units during operation (not independent). In CAN 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.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
*: This terminal is connected to the ECM.

After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode for “ENGINE” with CONSULT-II.
3. Wait at least 6 seconds or start engine and wait for at least 6
seconds.
WITHOUT CONSULT-II
1. Turn ignition switch “ON”.
2. Wait at least 6 seconds or start engine and wait at least 6 sec-
onds.
3. Perform self-diagnosis.
