ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Service After Replac-
ing TCM and Transaxle Assembly
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”.

Only one set of freeze frame data (either 1st trip freeze frame data or freeze frame data) can be stored in the
ECM. 1st trip freeze frame data is stored in the ECM memory along with the 1st trip DTC. There is no priority
for 1st trip freeze frame data, and it is updated each time a different 1st trip DTC is detected. However, once
freeze frame data (2nd trip detection/MI on) is stored in the ECM memory, 1st trip freeze frame data is no
longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-
lowing priorities to update the data.
Both 1st trip freeze frame data and freeze frame data (along with the DTC) are cleared when the ECM mem-
ory is erased.
How to Erase DTC
 The diagnostic trouble code can be erased by CONSULT-III, GST or ECM DIAGNOSTIC TEST MODE as
described below.
-If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.
-When erasing the DTC, using CONSULT-III or GST is easier and quicker than switching the mode
selector on the ECM.
 The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC
related to OBD. For details, refer to EC-389, "
DTCIndex".
-Diagnostic trouble codes (DTC)
-1st trip diagnostic trouble codes (1st trip DTC)
-Freeze frame data
-1st trip freeze frame data
-System readiness test (SRT) codes
-Test values
How to Erase DTC (With CONSULT-III)
The emission related diagnostic information in the TCM and ECM can be erased by selecting “All Erase” in the
“Description” of “FINAL CHECK” mode with CONSULT-III.
How to Erase DTC (With GST)
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2. Select Mode 4 with GST (Generic Scan Tool). For details, refer to EC-122, "
DiagnosisToolFunction".
MALFUNCTION INDICATOR (MI)
Description
The MI is located on the instrument panel.
1. The MI is turned ON when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
 If the MI is not turned ON, refer to EC-346, "
Component Func-
tion Check".
2. The MI is turned OFF when the engine is started. If the MI
remains ON, the on board diagnostic system has detected an
engine system malfunction.

COMPONENT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003806376
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.
