ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Precaution for TCM
and CVT Assembly Replacement
INFOID:0000000003848916
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.
EEPROM ERASING PATTERNS
METHOD FOR ERASING THE EEPROM IN THE TCM
1. Turn ignition switch ON.
2. Move selector lever to “R” position.
3. Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.
4. Press the brake pedal and turn the brake switch ON.
5. Press the accelerator pedal (0.5/8 - 4/8 throttle) not to exceed the half, and hold it in the half or less open
position. (This will set the closed throttle position signal to OFF and the wide open throttle position signal
to OFF.)
6. Perform “ERASE”.
7. Wait 3 seconds and then release the accelerator pedal.
8. Turn ignition switch OFF.
METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSAXLE
In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the
TCM.
1. Erase the EEPROM in the TCM.
2. Move selector lever to “P” position.
3. Turn ignition switch ON.
CHECK METHOD
 Standard: About 2 seconds after the ignition switch ON, the CVT indicator lamp lights up for 2 seconds.
 Non-standard: Even after the ignition switch ON, the CVT indicator lamp does not light up after 2 seconds or
illuminates immediately.
CAUTION:
Perform in the “P” or “N” position.
Action for Non-standard
 Replace the CVT assembly.
 Replace the TCM.
CVT assembly TCM Erasing EEPROM in TCM Remarks
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.
Replaced Not replaced RequiredRequired because data has been written in the EE-
PROM in the TCM and because the TCM cannot write
data from the ROM assembly in the transmission.

TM-138
< PRECAUTION >[CVT: RE0F09B]
PRECAUTIONS
Precaution
INFOID:0000000003849071
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.
TM-111, "
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:0000000003849072
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-37, "
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.

INFOID:0000000003806346
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.
NOTE:
Old unit means that the unit has been already used for another vehicle.
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.
11. Wait approximately 10 seconds after turning the ignition switch OFF.
12. Turn the ignition switch ON while shifting the selector lever to “R” position.
CAUTION:
Never start engine.
13. Select “Special Function” mode for “TRANSMISSION”.
14. Check that the value on “CALIBRATION DATA” is the same as the data after erasing “Calibration Data”.

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, "
