PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003901480
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for On Board Diagnosis (OBD) System of CVT and EngineINFOID:0000000003806496
The ECM has an on board diagnostic system. It will light up the Malfunction Indicator Lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
 Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid
valves, etc. will cause the MIL to light up.
 Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
 Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
 Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system, etc.
 Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precaution for TCM and CVT Assembly ReplacementINFOID:0000000003806497
CAUTION:
 Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-III, and then turn ignition switch OFF.)
 When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.

Replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state. (CVT assembly must be replaced
first.)
Not replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state.

Rotate bayonet ring (1) counterclockwise. Pull out CVT unit harness
connector (2) upward and remove it.
INSTALLATION
1. Align ∆ marking on CVT unit harness connector terminal body
with o marking on bayonet ring. Insert CVT unit harness connec-
tor. Then rotate bayonet ring clockwise.
2. Rotate bayonet ring clockwise until ∆ marking on CVT unit har-
ness connector terminal body is aligned with the slit on bayonet
ring as shown in the figure (correctly fitting condition). Install
CVT unit harness connector to CVT unit harness connector ter-
minal body.
CAUTION:
 Securely align ∆ marking on CVT unit harness connector
terminal body with bayonet ring slit. Then, be careful not
to make a half fit condition as shown in the figure.
 Never mistake the slit of bayonet ring for other dent por-
tion.

NOTE:
If any malfunction occurs in the RE0F10A model transaxle, replace the entire transaxle assembly.

< PRECAUTION >[CVT: RE0F10A]
PRECAUTIONS
Turn ignition switch OFF and disconnect negative battery
cable before connecting or disconnecting the TCM harness
connector. Because battery voltage is applied to TCM even if
ignition switch is turned OFF.
When connecting or disconnecting pin connectors into or
from TCM, do not damage pin terminals (bend or break).
Check that there are not any bends or breaks on TCM pin ter-
minal, when connecting pin connectors.
Perform TCM input/output signal inspection and check
whether TCM functions normally or not before replacing TCM.
Refer to TM-275, "
Reference Value".
Perform “DTC Confirmation Procedure” after performing each
TROUBLE DIAGNOSIS.
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-11, "
Flu-
ids and Lubricants".
 Use lint-free paper, not cloth rags, during work.
 Dispose of the waste oil using the methods prescribed by law, ordi-
nance, etc. after replacing the CVT fluid.
Service Notice or PrecautionINFOID:0000000003806500
OBD SELF-DIAGNOSIS
 CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the Malfunction Indicator (MI). Refer to the table on TM-204, "
CONSULT-III Function
(TRANSMISSION)" for the indicator used to display each self-diagnostic result.
 The self-diagnostic results indicated by the MI are automatically stored in both the ECM and TCM memories.
Always perform the procedure on TM-202, "
Diagnosis Description" to complete the repair and avoid
unnecessary blinking of the MIL.
For details of OBD, refer to EC-102, "
Diagnosis Description".

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.

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".

INSPECTION
1. Place selector lever in “P” position, and turn ignition switch ON (engine stop).
2. Check that selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
check that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Check that selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check that the actual position of the selector lever matches the position shown by the shift
position indicator and the manual lever on the transaxle.
5. The method of operating the selector lever to individual posi-
tions correctly should be as shown.
6. When selector button is pressed in “P”, “R”, “N”, “D” or “L” posi-
tion without applying forward/backward force to selector lever,
check button operation for sticking.
7. Check that back-up lamps illuminate only when selector lever is
placed in the “R” position.
8. When in “R” position, check that back-up lamps illuminate even
when the selector lever is pushed toward the “P” position.
CAUTION:
Check the lighting without pressing shift button.
9. Check that the back-up lamps do not illuminate when selector lever is pushed toward the “R” position
when in the “P” or “N” position.
CAUTION:
Check the lighting without pressing shift button.
10. Check that the engine can only be started with the selector lever in the “P” and “N” positions.
11. Check that transaxle is locked completely in “P” position.
ADJUSTMENT
1. Place selector lever in “ P” position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park lock.
2. Loosen nut (A) and place manual lever (B) in “P” position.
CAUTION:
Never apply any force to the manual lever.
3. Tighten nut. Refer to TM-319, "
Exploded View".
