Using the engine load (throttle position), the primary pulley revolution speed, and the secondary pulley revolu-
tion speed as input signal, TCM changes the operating pr essure of the primary pulley and the secondary pul-
ley and changes the groove width of the pulley to control the gear ratio.
CONSULT-III Reference Val ue in Data Monitor ModeINFOID:0000000005397908
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005397909
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0841” with CONSULT-III is detected when secondary fluid pressure is too high
compared with the commanded value while driving.
Possible CauseINFOID:0000000005397910
• Secondary pressure sensor
• Harness or connectors (Sensor circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005397911
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Start engine and maintain the following conditions for at least 12 consecutive seconds. VEHICLE SPEED: 40 km/h (25 MPH) More than
RANGE: “D” position
3. If DTC is detected, go to CVT-109, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005397912
1.CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis. Refer to CVT-48, "
CONSULT-III Function (TRANSMISSION)".
Is any malfunction of the
“U1000” indicated?
YES >> Check CAN communication line. Refer to CVT-56.
NO >> GO TO 2.
2.CHECK INPUT SIGNALS
With CONSULT-III
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONITO R” mode for “TRANSMISSION” with CONSULT-III.
3. Start vehicle and read out the value of “SEC HYDR SEN” and “PRI HYDR SEN”.
Item nameCondition Display value (Approx.)
PRI HYDR SEN “N” position idle 0.7 V
SEC HYDR SEN 1.0 V

DTC Confirmation ProcedureINFOID:0000000005397917
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Make sure that output voltage of CVT fluid temperature sensor is within the range below.
ATF TEMP SEN: 1.0 - 2.0 V
If out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to
increase the voltage (c ool down the fluid)
3. Start engine and maintain the following conditions for at least 10 consecutive seconds. VEHICLE SPEED (accelerate slowly): 0 → 50 km/h (31 MPH)
ACC PEDAL OPEN: 0.5/8 - 1.0/8
RANGE: “D” position
4. If DTC is detected, go to CVT-111, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005397918
