DTC P0734 A/T 4TH GEAR FUNCTION
3. Select “4TH GR FNCTN P0734” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 55 to 65 km/h (34 to 40 MPH) under the
following condition and release the accelerator pedal com-
pletely.
THROTTLE POSI: Less than 5.5/8 (at all times during step 4)
Selector lever: D position (OD “ON”)
lCheck that “GEAR” shows “3” after releasing pedal.
5. Depress accelerator pedal steadily with 1.0/8 - 2.0/8 of “THROT-
TLE POSI” from a speed of 55 to 65 km/h (34 to 40 MPH) until
“TESTING” has turned to “STOP VEHICLE” or “COMPLETED”.
(It will take approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to “DIAGNOSTIC PROCEDURE”,AT-176,
"Diagnostic Procedure".
If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.
lCheck that “GEAR” shows “4” when depressing accelerator pedal with 1.0/8 - 2.0/8 of “THROTTLE
POSI”.
lIf “TESTING” does not appear on CONSULT-II for a long time, select “SELF-DIAGNOSIS” for
“ENGINE”. In case a 1st trip DTC other than P0734 is shown, refer to applicable “TROUBLE DIAG-
NOSIS FOR DTC”.

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.

TROUBLE DIAGNOSES FOR SYMPTOMS
21. TCM Self-diagnosis Does Not Activate (PNP & Overdrive Control Switches,
and Throttle Position Sensor Circuit Checks)
ECS0 04 T E
SYMPTOM:
O/D OFF indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit is
good.
DESCRIPTION
lPNP switch
The PNP switch assembly includes a transmission position switch. The transmission position switch
detects the selector lever position and sends a signal to the TCM.
lOverdrive control switch
Detects the overdrive control switch position (ON or OFF) and sends a signal to the TCM.
lThrottle position sensor *
*: This sensor means accelerator pedal position (APP) senror.
Electric throttle control actuator consists of throttle control motor, acceleration pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the TCM.
