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. |
| Typical enabling condition | 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. |
| Sequence of operation | While a sensor is being monitored, a 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. |
| Frequency of operation | "Once per driving cycle" means that the ECM detects a malfunction only one time during a single driving cycle. |

- 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 to 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 less than -10°C (14°F)). Notice in driving Drive the vehicle through all gears. Stop -> 1st -> 2nd -> 3rd -> 4th -> 5th -> 5th (lock-up 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. Perform this drive pattern on a level road as much as possible and strictly observe the posted speed limits and traffic laws while driving. HINT: *1: Drive at such a speed in the uppermost gear, to engage lock-up. The vehicle can be driven at a speed lower than that in (Scheme 229) under the lock-up condition. NOTE: It is necessary to drive the vehicle for approximately 30 minutes to detect DTC P0711 (ATF temperature sensor malfunction).
NORMAL MODE AND CHECK MODE
The diagnosis system operates in "normal mode" during normal vehicle use. In normal mode, "2-trip detection logic" is used to ensure accurate detection of malfunctions. "Check mode" is also available to technicians as an option. In check mode, "1-trip detection logic" is used for simulating malfunction symptoms and increasing the system's ability to detect malfunctions, including intermittent malfunctions.
Scheme 230
2-TRIP DETECTION LOGIC
When a malfunction is first detected, the malfunction is temporarily stored in the ECM memory (1st trip). If the ignition switch is turned OFF and then ON again, and the same malfunction is detected again, the MIL will illuminate.
FREEZE FRAME DATA
Freeze frame data records the engine conditions (fuel system, calculated load, engine coolant temperature, fuel trim, engine speed, vehicle speed, etc.) when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air/fuel ratio was Lean or Rich, and other data from the time the malfunction occurred.
The hand-held tester records freeze frame data in five different instances: 1) 3 times before the DTC is set, 2) once when the DTC is set, and 3) once after the DTC is set. These data can be used to simulate the vehicle's condition around the time when the malfunction occurred. The data may help find the cause of the malfunction, or judge if the DTC is being caused by a temporary malfunction or not.
Scheme 231
DLC3 (Data Link Connector 3)
The vehicle's ECM uses the ISO 15765-4 for communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format.
HINT
Connect the cable of the hand-held tester to the DLC3, turn the ignition switch ON and attempt to use the hand-held tester. If the screen displays UNABLE TO CONNECT TO VEHICLE, a problem exists in the vehicle side or the tester side.
If the communication is normal when the tool is connected to another vehicle, inspect the DLC3 on the original vehicle.
If the communication is still impossible when the tool is connected to another vehicle, the problem is probably in the tool itself. Consult the Service Department listed in the tool's instruction manual.

CHECK BATTERY VOLTAGE
Battery voltage: 11 to 14 V
If voltage is below 11 V, replace the battery before proceeding.
CHECK MIL
- Check that the MIL illuminates when turning the ignition switch ON. If the MIL does not illuminate, there is a problem in the MIL circuit (refer to «MIL CIRCUIT»(ref-228749-S04697796732007052500000) )
- When the engine is started, the MIL should turn off.
ALL READINESS
For this vehicle, using the hand-held tester allows readiness codes corresponding to all DTCs to be read. When diagnosis (normal or malfunctioning) has been complete, readiness codes are set. Enter the following menus: ENHANCED OBD II/MONITOR STATUS on the hand-held tester.
Scheme 233
- CHECK DTC DTCs which are stored in the ECM can be displayed with the hand-held tester or generic OBD II scan tool. These scan tools can display pending DTCs and current DTCs. Some DTC aren't stored if the ECM doesn't detect a malfunction during consecutive driving. However, the detected malfunction during once driving is stored as pending DTC. Connect the hand-held tester to the Controller Area Network Vehicle Interface Module (CAN VIM). Then connect the CAN VIM to the Data Link Connector 3 (DLC3). Turn the ignition switch ON. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES (or PENDING CODE). Confirm the DTCs and freeze frame data and then write them down. See «DIAGNOSTIC TROUBLE CODE TABLE»(ref-228754-S20843591202006041100000) to confirm the details of the DTCs. NOTE: When simulating a symptom with the scan tool to check for DTCs, use normal mode. For codes on DIAGNOSTIC TROUBLE CODE TABLE subject to "2-trip detection logic", perform the following actions. Turn the ignition switch OFF after the symptom is simulated once. Then repeat the simulation process again. When the problem has been simulated twice, the MIL illuminates and the DTCs are recorded in the ECM.
- CLEAR DTC Connect the hand-held tester to the CAN VIM. Then connect the CAN VIM to the DLC3. Turn the ignition switch ON. Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CLEAR CODES and press YES.

- CHECK OTHER DTCS OUTPUT (IN ADDITION TO PTC P0781) Connect the OBD II scan tool or the hand-held tester to the DLC3. Turn the ignition switch to the ON position and push the OBD II scan tool or the hand-held tester main switch ON. When you use hand-held tester: Select the item "DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES". Read the DTCs using the OBD II scan tool or the hand-held tester. Result: OTHER DTCS OUTPUT (IN ADDITION TO PTC P0781) Display (DTC output) Proceed to Only "P0781" is output A "P0781" and other DTCs B HINT: If any other codes besides "P0781" are output, perform troubleshooting for those DTCs first. B: GO TO «DIAGNOSTIC TROUBLE CODE TABLE»(ref-228754-S20843591202006041100000) A: Go to next step.
- PERFORM ACTIVE TEST BY HAND-HELD TESTER 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 together with the CAN VIM (controller area network vehicle interface module) to the DLC3. Turn the ignition switch to the ON position. Turn on the tester. Select the item "DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST / SHIFT". According to the display on the tester, perform the "ACTIVE TEST". HINT: While driving, the shift position can be forcibly changed with the hand-held tester. Comparing the shift position commanded by the ACTIVE TEST with the actual shift position enables you to confirm the problem (See «FAIL-SAFE TABLE»(ref-228754-S01632432172006041100000) ). HINT: This test can be conducted when the vehicle speed is 50 km/h (31 mph) or less. The 4th to 5th up-shiftings must be performed with the accelerator pedal released. The 5th to 4th down-shiftings must be performed with the accelerator pedal released. Do not operate the accelerator pedal for at least 2 seconds after shifting and do not shift successively. The shift position commanded by the ECM is shown in the DATA LIST (SHIFT) display on the hand-held tester. OK: Gear position changes in accordance with the tester command. NG: REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSY (SEE «TRANSMISSION VALVE BODY ASSY»(ref-228796-S05223383022006041100000) ) OK: Go to next step.
- CLEAR THE PTC AND RUNNING TEST Clear the DTC, and check DTC again after conducting the "MONITOR DRIVE PATTERN FOR ECT TEST" (See «MONITOR DRIVE PATTERN»(ref-228754-S00981861842006041100000) ). OK: No DTC code NG: REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSY (SEE «TRANSMISSION VALVE BODY ASSY»(ref-228796-S05223383022006041100000) ) OK: END
