P Output Speed Sensor (Secondary Speed Sensor)
The shift pattern is changed in accordance with the throttle position when an unexpected signal is sent from
the output speed sensor (secondary speed sensor) to the TCM. The sport mode is inhibited, and the transaxle
is put in “D”.
Input Speed Sensor (Primary Speed Sensor)
The shift pattern is changed in accordance with the 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 sport
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 5,000
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 inputted to the TCM, sec-
ondary 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 valve to the TCM, the pressure control solenoid A (line pres-
sure 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 valve to the TCM, the pressure control solenoid B (secondary
pressure 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 valve to the TCM, the torque converter clutch solenoid valve
is turned OFF to cancel the lock-up.
Ste p M oto r
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 valve 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 the TCM. Normal status is restored when turning the ignition
switch OFF to ON after the normal power supply.
DTC Inspection Priority ChartINFOID:0000000003849062
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 indicated with other DTCs, start from a diagnosis for “DTC
U1000 CAN COMMUNICATION LINE”. Refer to TM-41

ROAD TEST
ROAD TEST
DescriptionINFOID:0000000003849080
DESCRIPTION
 The purpose of the test is to determine the overall performance of
CVT and analyze causes of problems.
 The road test consists of the following three parts:
1. “Check Before Engine Is Started” TM-148

.
 Before the road test, familiarize yourself with all test procedures
and items to check.
 Perform tests for all the check items until a malfunction phenome-
non is detected. Perform diagnosis for NG items after the comple-
tion of road tests.

SERVICE AFTER REPLACING TCM AND TRANSAXLE ASSEMBLY
Perform the applicable service according to the following sheet when replacing TCM or transaxle assembly.
CAUTION:
 Never start the engine until the service is completed.
 “TCM-POWER SUPPLY [P1701]” may be indicated soon after replacing TCM or transaxle assembly
(after erasing the memory at the pattern B). Restart the self-diagnosis after erasing the self-diagnosis
result. Check that no error is detected.

PATTERN A
1. Shift the selector lever to “P” position after replacing TCM. Turn the ignition switch ON.
2. Check that the shift position indicator in the combination meter turns ON (It indicates approximately 1 or 2
seconds after turning the ignition switch ON.)
 Check the following items if the shift position indicator does not turn ON. Repair or replace the shift posi-
tion indicator if necessary.
- The harness between TCM and ROM ASSY in the transaxle assembly is open or shorted.
- Cable disconnected, loosen, or bent from the connector housing.
PATTERN B
1. Turn the ignition switch ON after replacing each part.
2. Start engine.
CAUTION:
Never start driving.
3. Select “Data Monitor” mode for “TRANSMISSION”.
4. Warm up the transaxle assembly until “ATFTEMP COUNT” indicates 47 [approximately 20°C (68°F)] or
more. Turn the ignition switch OFF.
5. Turn the ignition switch ON.
CAUTION:
Never start engine.
6. Select “Self Diagnostic Results” mode for “TRANSMISSION”.
7. Shift the selector lever to “R” position.
8. Depress slightly the accelerator pedal (Pedal angle: 2/8) while depressing the brake pedal.
9. Perform “Erase”.
10. Shift the selector lever to “R” position after replacing TCM. Turn the ignition switch OFF.

HYDRAULIC CONTROL SYSTEM
Normal Control
Optimize the line pressure and secondary pressure, depending on driving conditions, on the basis of the throt-
tle position, the engine speed, the primary pulley (input) revolution speed, the secondary pulley (output) revo-
lution speed, the brake signal, the PNP switch signal, the lock-up signal, the voltage, the target gear ratio, the
fluid temperature, and the fluid pressure.
Feedback Control
For the normal fluid control and the select fluid control, secondary pressure is detected for feedback control by
using a secondary pressure sensor to set a high-precision secondary pressure.
