Diagnostic ProcedureECS004S8
1.CHECK DTC WITH ECM
Perform diagnostic test mode II (self-diagnostic results) for engine control.
Refer to EC-58, "
Malfunction Indicator (MI)" (QR25DE) or EC-790, "Malfunction Indicator (MI)" (QR20DE).
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.
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.

3. CHECK INPUT SIGNAL (WITHOUT CONSULT-II)
Without CONSULT-II
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 >> GO TO 4.
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit.
4. CHECK DTC
Perform Diagnostic Trouble Code (DTC) confirmation procedure. Refer to AT- 1 8 1 , "
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. Voltage:
Fully-closed throttle valve: Approximately 0.5V
Fully-open throttle valve: Approximately 4V

DTC P1760 OVERRUN CLUTCH SOLENOID VALVEPFP: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. Accelerate vehicle to a speed of more than 10 km/h (6 MPH)
with “D” position (OD “ON”).
4. Release accelerator pedal completely with “D” position (OD “OFF”).
With GST
Follow the procedure “With CONSULT-II”.

Diagnostic Procedure
ECS004SB
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 to AT- 4 1 4 ,
"REMOVAL" .
2. Check the following items:
–Overrun clutch solenoid valve
Refer to AT-189, "
Component 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.
4. Reinstall any part removed.

DTC U1000 CAN COMMUNICATION LINE
DTC U1000 CAN COMMUNICATION LINE
PFP:31940
DescriptionECS008CZ
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. 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 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.
