Inspection Procedure
1. CHECK CONNECTOR
1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector and steer-
ing angle sensor connector. Check terminal for deformation, disconnection, looseness, and so on. If any
malfunction is found, repair or replace terminal.
2. Securely reconnect connectors and perform self-diagnosis.
Is above displayed in the self-diagnosis item?
YES >> Print out self-diagnostic results and go to LAN-49, "CAN System Specification Chart" .
NO >> Connector terminal connection is loose, damaged, open or shorted.

Precautions BCS001FT
NOTE:
If any malfunction occurs in the RE0F09A model transaxle, replace the entire transaxle assembly.

Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect the battery
cable from the negative terminal. Because battery voltage is
applied to TCM even if ignition switch is turned OFF.

When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are
not any bends or breaks on TCM pin terminal.

Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. Refer to CVT-40, "
TCM INSPECTION TABLE".

After performing each TROUBLE DIAGNOSIS, perform “DTC Confirmation Procedure”.
If the repair is completed the DTC should not be displayed in the “DTC Confirmation Procedure”.

Always use the specified brand of CVT fluid. Refer to MA-14, "Fluids and Lubricants" .

Use lint-free paper, not cloth rags, during work.

After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance,
etc.

TROUBLE DIAGNOSIS

TROUBLE DIAGNOSISPFP:00004
DTC Inspection Priority ChartBCS001GE
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 CVT-53
.
Fail-safeBCS001GF
The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is an error in a
main electronic control input/output signal circuit.
FAIL-SAFE FUNCTION
If any malfunction occurs in a sensor or solenoid, this function controls the CVT to make driving possible.
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 position and second position 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 position and second position 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”.
Manual Mode Switch
If an unexpected signal is sent from the manual mode 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 input to TCM, second-
ary pressure feedback control stops, but line pressure is controlled normally.
Pressure Control Solenoid A (Line Pressure Solenoid)
If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid A (line pressure
solenoid) is turned OFF to achieve the maximum fluid pressure.
Pressure Control Solenoid B (Secondary Pressure Solenoid)
If an unexpected signal is sent from the solenoid to the TCM, the pressure control solenoid B (secondary pres-
sure solenoid) is turned OFF to achieve the maximum fluid pressure.
Torque Converter Clutch Solenoid
If an unexpected signal is sent from the solenoid to the TCM, the torque converter clutch solenoid is turned
OFF to cancel the lock-up.

Road TestBCS001GK
DESCRIPTION

The purpose of the test is to determine overall performance of
CVT and analyze causes of problems.

The road test consists of the following three parts:
1. “Check Before Engine Is Started” CVT-37
.
2. “Check at Idle” CVT-37
.
3. “Cruise Test” CVT-38
.

Before road test, familiarize yourself with all test procedures and
items to check.

Perform tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
CONSULT-II OPERATION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.

Using CONSULT-II, 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 “SELECT DIAG MODE” screen.
2. Touch “MAIN SIGNALS” to set recording condition.
3. See “Numerical Display”, “Barchart Display” or “Line Graph Dis-
play”.
4. Touch “START”.
