OBD-II DRIVE CYCLE PATTERN
Start the engine, and drive at 100 km/h (62 mph) for
10 seconds. Then stop the vehicle, and turn OFF the
ignition switch. After that, restart the engine, and drive
again at 100 km/h (62 mph) for 10 seconds.

DESCRIPTIONS OF MONITOR METHODS
⦆
When the input shaft speed sensor and the output
shaft speed sensor are normal at the "D" range, the
engine speed signal is normal, and within the non-
lock-up operation range, the extremely low slip
speed of the torque converter is detected
continuously for a specified time. (P0742)

Check Conditions
⦆
Output speed: more than 1,000 r/min.
⦆
Solenoid status: 5 seconds after not plunging into
connecting condition.
⦆
Transmission range switch position: D.
⦆
Input shaft speed sensor: normality.
⦆
Output shaft speed sensor: normality.
Judgement Criteria
⦆
Calculated slip (engine speed - input shaft speed):
5 r/min or less. (5 seconds)
OBD-II DRIVE CYCLE PATTERN
Start the engine, and drive at 30 km/h (19 mph) for 30
seconds. Then stop the vehicle, and turn
"LOCK" (OFF) the ignition switch. After that, restart
the engine, and drive again at 30 km/h (19 mph) for
30 seconds.
TROUBLESHOOTING HINTS (THE MOST LIKELY
CAUSES FOR THIS CODE TO BE SET ARE:)
⦆
Malfunction of the P0743: lock-up and low-reverse
brake linear solenoid valve system circuit
⦆
Malfunction of the P0712: transmission fluid
temperature sensor system (short circuit)
⦆
Malfunction of the P0713: transmission fluid
temperature sensor system (open circuit)
⦆
Poor installation of the engine and A/T (deviation to
the axial direction)
⦆
Malfunction of the torque converter
⦆
Malfunction of the valve body assembly
DIAGNOSIS
STEP 1. Hydraulic pressure test
Refer to P.23A-21.
Q:Is the check result normal?
YES:
Go to Step 2.
NO:
Repair or replace the failure section.
STEP 2. Check the lock-up and low-reverse brake linear
solenoid.
Check for P0743 (lock-up and low-reverse brake linear
solenoid). Refer to P.23A-64.
Q:Is the check result normal?
YES:
Go to Step 3.
NO:
Repair or replace the failure section.
STEP 3. Check the transmission fluid temperature sensor,
input shaft speed sensor, and output shaft speed sensor.
Check the following DTCs: P0712 (transmission fluid
temperature sensor (short circuit)), P0713 (transmission fluid
temperature sensor (open circuit)), P0715 (input shaft speed
sensor) and P0720 (output shaft speed sensor).
Refer to P.23A-30(P0712), P.23A-34(P0713), P.23A-37
(P0715), P.23A-42(P0720).
Q:Is the check result normal?
YES:
Go to Step 4.
NO:
Repair or replace the failure section.
STEP 4. Check the malfunction of CAN communication
system.
Q:Are the DTC for CAN communication system malfunction
(U0001, U0100, U0141, P1705, P1706) set?
YES:
Repair or replace the failure section.
