DEFINITION OF TERMS
| Term | Definition |
|---|---|
| Monitor description | Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details). |
| Related DTCs | A group of diagnostic trouble codes that are output by the ECM based on the same malfunction detection logic. |
| Typical enabling condition | Preconditions that allow the ECM to detect malfunctions. With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the malfunction threshold(s). |
| Sequence of operation | The priority order that is applied to monitoring, If multiple sensors and components are used to detect the malfunction. While another sensor is being monitored, the next sensor or component will not be monitored until the previous monitoring has concluded. |
| Required sensor/components | The sensors and components that are used by the ECM to detect malfunctions. |
| Frequency of operation | The number of times that the ECM checks for malfunctions per driving cycle. "Once per driving cycle" means that the ECM detects malfunction only one time during a single driving cycle. "Continuous" means that the ECM detects malfunction every time when enabling condition is met. |
| Duration | The minimum time that the ECM must sense a continuous deviation in the monitored value(s) before setting a DTC. This timing begins after the "typical enabling conditions" are met. |
| Malfunction thresholds | Beyond this value, the ECM will conclude that there is a malfunction and set a DTC. |
| MIL operation | MIL illumination timing after a defect is detected. "Immediately" means that the ECM Illuminates MIL the Instant the ECM determines that there is a malfunction. "2 driving cycle" means that the ECM Illuminates MIL if the same malfunction is detected again in the 2nd driving cycle. |
| Component operating range | Normal operation range of sensors and solenoids under normal driving conditions. Use these ranges as a reference. They cannot be used to judge if a sensor or solenoid is defective or not. |

SYSTEM DIAGRAM
The configuration of the electronic control system in the U241E/U140F automatic transaxles is as shown in the following chart.
Scheme 249
INITIALIZATION
- RESET MEMORY
| CAUTION | Perform the RESET MEMORY (AT initialization) when replacing the automatic transaxle assy, engine assy or ECM. |
Note. Hand-held tester only
HINT
The ECM memorizes the condition that the ECT controls the automatic transaxle assy and engine assy according to those characteristics. Therefore, when the automatic transaxle assy, engine assy, or ECM has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information. Reset procedure is as follows.
- Turn the ignition switch off.
- Connect the hand-held tester to the DLC3.
- Turn the ignition switch to the ON position and push the hand-held tester main switch on.
- Select the item "DIAGNOSIS/ENHANCED OBD II".
- Perform the reset memory procedure from the ENGINE menu.
| CAUTION | After performing the RESET MEMORY, be sure to perform the ROAD TEST (See ROAD TEST ) described earlier. |
HINT
The ECM is learned by performing the ROAD TEST.
Scheme 250
LIST OF DISABLE A MONITOR
HINT
This table indicates ECM monitoring status for the items in the upper columns if the DTCs in each line on the left are being set.
As for the "X" mark, when the DTC on the left is stored, detection of the DTC in the upper column is not performed.

MONITOR DRIVE PATTERN
- MONITOR DRIVE PATTERN FOR ECT TEST
- Perform this drive pattern as one method to simulate the detection conditions of the ECT malfunctions. (The DTCs may not be detected due the actual driving conditions. And some codes may not be detected through this drive pattern).
HINT
Preparation for driving
- Warm up the engine sufficiently. (Engine coolant temperature is 60°C (140°F) or higher)
- Drive the vehicle when the atmospheric temperature is -10°C (14°F) or higher. (Malfunction is not detected when the atmospheric temperature is -10°C (14°F) or less)
Driving note
- Drive the vehicle through all gears. Stop -> 1st -> 2nd -> 3rd -> O/D -> O/D (lockup ON).
- Repeat the above driving pattern three times or more.
Note. The monitor status can be checked using the OBD II scan tool. When using the hand-held tester, monitor status can be found In the "ENHANCED OBD II/DATA LIST" or under "CARB OBD II". In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other factors) the drive pattern can be resumed and, in most cases, the monitor can be completed.
| CAUTION | Perform this drive pattern on a level road as much as possible and strictly observe the posted speed limits and traffic laws while driving. |
Scheme 257
HINT
*1: Drive at such a speed in the uppermost gear, to engage lockup. The vehicle can be driven at a speed lower than that in the above diagram under the lockup condition.
Note. It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (ATF temperature sensor malfunction).
FAIL-SAFE CHART
- FAIL-SAFE
This function minimizes the loss of the ECT functions when any malfunction occurs in each sensor or solenoid.
- ATF (Automatic Transmission Fluid) temperature sensor: When the ATF temperature sensor has a malfunction, O/D upshift is prohibited.
- Counter gear speed sensor NC (Speed sensor NC): When the counter gear speed sensor has a malfunction, O/D upshift is prohibited.
- Shift solenoid valve DSL: When the solenoid valve DSL has a malfunction, the current to the solenoid valve is stopped. This stops lockup control, then fuel economy decreases.
- Shift solenoid valve SL1, SL2 and S4
Fail safe function
If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift solenoid "ON" and "OFF" in order to shift into the gear positions shown in the table below.
Manual shifting as shown in the following table must be done (In case of a short circuit, the ECM stops sending the current to the short circuit solenoid).
Even if starting the engine in the fail-safe mode, the gear position remain in the same position.

- DATA LIST HINT: According to the DATA LIST displayed by the OBD II scan tool or hand-held tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor time. Warm up the engine. Turn the ignition switch off. Connect the OBD II scan tool or hand-held tester to the DLC3. Turn the ignition switch to the ON position. Push the "ON" button of the OBD II scan tool or the hand-held tester. When you use hand-held tester: Select the item "DIAGNOSIS/ENHANCED OBD II/DATA LIST". According to the display on tester, read the "DATA LIST".
- ACTIVE TEST
HINT
Performing the ACTIVE TEST using the hand-held tester allows the relay, VSV, actuator and so on to operate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one method to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
- Warm up the engine.
- Turn the ignition switch off.
- Connect the hand-held tester to the DLC3.
- Turn the ignition switch to the ON position.
- Push the "ON" button of the hand-held tester.
- Select the item "DIAGNOSIS/ENHANCED OBD II/ACTIVE TEST".
- According to the display on tester, perform the "ACTIVE TEST".

The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.
