TCM FunctionINFOID:0000000001327135
The function of the TCM is to:
 Receive input signals sent from various switches and sensors.
 Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
 Send required output signals to the respective solenoids.
CONTROL SYSTEM OUTLINE
The automatic transmission senses vehicle operating condi tions through various sensors or signals. It always
controls the optimum shift position and reduces shifting and lock-up shocks.

LINE PRESSURE TEST
Line Pressure Test Port
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the ATF reaches in range of 50 to 80°C (122 to
176 °F), then inspect the amount of ATF and replenish if necessary.
NOTE:
The A/T fluid temperature rises in range of 50 to 80°C (122 to 176 °F) during 10 minutes of driving.
3. Remove the front propeller shaft from vehicle (with AWD models). Refer to PR-4, "
Removal and Installa-
tion".
4. After warming up remove the oil pressure detection plug and install the oil pressure gauge [ST2505S001(J-34301-C)].
CAUTION:
When using the oil pressure ga uge, be sure to use the O-
ring attached to the oil pressure detection plug.

DTC P0717 TURBINE REVOLUTION SENSOR
DTC P0717 TURBINE REVOLUTION SENSOR
DescriptionINFOID:0000000001327190
The turbine revolution sensor detects input shaft rpm (revolutions per minute). It is located on the input side of
the automatic transmission. Monitors revolution of sensor 1 and sensor 2 for non-standard conditions.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001327191
On Board Diagnosis LogicINFOID:0000000001327192
Diagnostic trouble code “P0717 TURBINE REV S/CIRC” with CONSULT-III or 11th judgement flicker without
CONSULT-III is detected under the following conditions.
 When TCM does not receive the proper voltage signal from the sensor.
 When TCM detects an irregularity only at position of 4th gear for turbine revolution sensor 2.
Possible CauseINFOID:0000000001327193
 Harness or connectors
(Sensor circuit is open or shorted.)
 Turbine revolution sensor 1 and/or 2
DTC Confirmation ProcedureINFOID:0000000001327194
CAUTION:
 Always drive vehicle at a safe speed.
 Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “SELECTION FROM MENU” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “VHCL/S SE-A/T”, “ENGINE SPE ED”, “ACCELE POSI”, “SLCT LVR POSI” and
“GEAR”.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds. VHCL/S SE-A/T: 40 km/h (25 MPH) or more
ENGINE SPEED: 1,500 rpm or more
ACCELE POSI: More than 0.5/8
SLCT LVR POSI: “D” position
GEAR (Turbine revolution sensor 1): “4” or “5” position
GEAR (Turbine revolution sensor 2): All positions
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If DTC is detected, go to AT-106, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
Diagnosis ProcedureINFOID:0000000001327195
1.CHECK INPUT SIGNAL
With CONSULT-III
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
Item name Condition Display value
