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
.

ROAD TEST
ROAD TEST
DescriptionINFOID:0000000003806508
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-310
.
2. “Check at Idle” TM-311
.
3. “Cruise Test” TM-312
.
 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.
CONSULT-III SETTING PROCEDURE
 Using CONSULT-III, perform a cruise test and record the result.
 Print the result and ensure that shifts and lock-ups take place as per Shift Schedule.
1. Touch “Data Monitor” on “Direct Diagnostic Mode” screen.
2. Touch “MAIN SIGNALS” to set recording condition.
3. See “Numerical Display”, “Barchart Display” or “Line Graph Display”.
4. Touch “START”.
5. When performing cruise test. Refer to TM-312, "
Cruise Test".
6. After finishing cruise test part, touch “RECORD”.
7. Touch “STORE”.
8. Touch “BACK”.
9. Touch “DISPLAY”.
10. Touch “PRINT”.
11. Check the monitor data printed out.
Check before Engine Is StartedINFOID:0000000003806509
1.CHECK SHIFT POSITION INDICATOR
1. Park vehicle on flat surface.
2. Move selector lever to “P” position.
3. Turn ignition switch OFF. Wait at least 5 seconds.
4. Turn ignition switch ON. (Never start engine.)
Has shift position indicator been turned ON for about 2 seconds?
YES >> 1. Turn ignition switch OFF.
2. Perform self-diagnosis and note NG items.

SELF-DIAGNOSIS MODE
 Information display LCD segment operation can be checked in self-diagnosis mode.
 Meters/gauges can be checked in self-diagnosis mode.
OPERATION PROCEDURE
1. Turn ignition switch ON, and switch the trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” is reset to “0000.0”.
(The same way for “trip B”.)
2. Turn ignition switch OFF.
3. While pressing the trip reset switch (1), turn ignition switch ON
again.
4. Make sure that the trip meter displays “0000.0”.
5. Press the trip reset switch at least 3 times. (Within 7 seconds
after the ignition switch is turned ON.)
6. The unified meter control unit is turned to self-diagnosis mode.
 The segment dots of the information display LCD (1) blink
alternately.
 Water temperature gauge and fuel gauge return to zero, simul-
taneously.
NOTE:
 Check combination meter power supply and ground circuit when the self-diagnosis mode of the combi-
nation meter does not start. Replace combination meter if abnormal.
 If any of the segments are not displayed, replace combination meter.
