< ECU DIAGNOSIS >[CVT: RE0F10A]
TCM
Output Speed Sensor (Secondary Speed Sensor)
The shift pattern is changed in accordance with throttle position when an unexpected signal is sent from the
output speed sensor (secondary speed sensor) to the TCM. The manual mode is inhibited, and the transaxle
is put in “D”.
Input Speed Sensor (Primary Speed Sensor)
The shift pattern is changed in accordance with throttle position and secondary speed (vehicle speed) when
an unexpected signal is sent from the input speed sensor (primary speed sensor) to the TCM. The manual
mode is inhibited, and the transaxle is put in “D”.
PNP Switch
If an unexpected signal is sent from the PNP switch to the TCM, the transaxle is put in “D”.
CVT Fluid Temperature Sensor
If an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use before
receiving the unexpected signal is maintained or the gear ratio is controlled to keep engine speed under 5000
rpm.
Transmission Fluid Pressure Sensor A (Secondary Pressure Sensor)
If an unexpected signal is sent from the transmission fluid pressure sensor A (secondary pressure sensor) to
the TCM, the secondary pressure feedback control is stopped and the offset value obtained before the non-
standard condition occurs is used to control line pressure.
If transmission fluid pressure sensor A (secondary pressure sensor) error signal is input to TCM, secondary
pressure feedback control stops, but line pressure is controlled normally.
Pressure Control Solenoid A (Line Pressure Solenoid valve)
If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid A (line pressure
solenoid valve) is turned OFF to achieve the maximum fluid pressure.
Pressure Control Solenoid B (Secondary Pressure Solenoid valve)
If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid B (secondary pres-
sure solenoid valve) is turned OFF to achieve the maximum fluid pressure.
Torque Converter Clutch Solenoid valve
If an unexpected signal is sent from the solenoid to the TCM, the torque converter clutch solenoid valve is
turned OFF to cancel the lock-up.
Step Motor
If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are
all turned OFF to hold the gear ratio used just before the non-standard condition occurred.
CVT Lock-up Select Solenoid valve
If an unexpected signal is sent from the solenoid to the TCM, the CVT lock-up select solenoid valve is turned
OFF to cancel the lock-up.
TCM Power Supply (Memory Back-up)
Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (for
controlling) from the battery is not supplied to TCM. Normal status is restored when turning the ignition switch
OFF to ON after the normal power supply.
DTC Inspection Priority ChartINFOID:0000000003806490
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
NOTE:
If DTC “U1000 CAN COMM CIRCUIT” is displayed with other DTCs, first perform the trouble diagnosis
for “DTC U1000 CAN COMMUNICATION LINE”. Refer to TM-208

Ventilate work area before resuming service if accidental system discharge occurs. Additional health
and safety information may be obtained from refrigerant and lubricant manufacturers.
Never release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant each time an air conditioning system is discharged.
Wear always eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
Never store or heat refrigerant containers above 52°C (126°F).
Never heat a refrigerant container with an open flame; Place the bottom of the container in a warm
pail of water if container warming is required.
Never intentionally drop, puncture, or incinerate refrigerant containers.
Keep refrigerant away from open flames: poisonous gas is produced if refrigerant burns.
Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo-
cation.
Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refriger-
ant manufacturers.
Refrigerant ConnectionINFOID:0000000003802523
A new type refrigerant connection has been introduced to all refrigerant lines except the following locations.
Expansion valve to evaporator
Refrigerant pressure sensor to liquid tank
O-RING AND REFRIGERANT CONNECTION
CAUTION:
The new and former refrigerant connections use different O-ring configurations. Never confuse O-
rings since they are not interchangeable. Refrigerant may leak at the connection if a wrong O-ring is
installed.

PRECAUTIONS
Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must equip positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite to the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers do
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. The hose fitting must
be 1/2″-16 ACME if the scale controls refrigerant flow electronically.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale each three month.
To calibrate the weight scale on the ACR4:
1. Press “Shift/Reset” and “Enter” at the same time.
2. Press “8787”. “A1” is displayed.
3. Remove all weight from the scale.
4. Press “0”, then press “Enter”. “0.00” is displayed and change to “A2”.
