IGNITION SWITCH EXPRESSIONS
The type of ignition switch used on this model differs according to the specifications of the vehicle. The expressions listed in the table below are used in this section.
| Expression | Ignition Switch (Position) |
Engine Switch (Condition) |
|---|---|---|
| Ignition Switch off | LOCK | Off |
| Ignition Switch ON | ON | On (IG) |
| Ignition Switch ACC | ACC | On (ACC) |
| Engine Start | START | Start |
PRECAUTION REGARDING ON-VEHICLE INSPECTION
When racing the engine, make sure that the gear is in neutral.
PRECAUTION REGARDING PARTS REMOVAL
Before removing the clutch actuator or transaxle assembly from the vehicle, perform the Active Test to set the clutch actuator to the "Clamp" position Click here.
Note
If the actuator is not set to the "Clamp" position, the clutch fluid may be sprayed out.
Tech Tips
If the clutch actuator cannot be set to the "Clamp" position due to a malfunction (sticking, etc.), then the clutch fluid pressure should be released from the bleeder plug to prevent the fluid from spraying.
PRECAUTION REGARDING PARTS INSTALLATION
Before installing the clutch actuator or transaxle assembly onto the vehicle, perform the Active Test to set the clutch actuator to the "Clamp" position Click here
If clutch fluid line parts are installed, bleed the air from the lines before performing initialization Click here.
When installing parts related to the multi-mode manual transmission system, perform [Initialization and Learning] and/or [Synchronization Position Calibration]. In addition, the required operations differ according to the parts to be installed. Proceed with the operation in the order shown in the table below.
| Part Installed | Operation Order | See Procedure |
|---|---|---|
|
1. Initialization of Multi-Mode Manual Transaxle System [Initialization of ECU] |

1. Initialization of Multi-Mode Manual Transaxle System [Initialization of clutch] |
|
| 2. Learning of Multi-Mode Manual Transaxle System |
Note
If the transaxle assembly is removed from the vehicle, a new clutch release with bearing cylinder assembly must be used when it is reinstalled.
After replacing any system components, perform initialization and learning of related components (refer to the operations listed above). If initialization and learning are not performed, the transaxle system will not function properly.
Before proceeding with learning of the multi-mode manual transaxle system, clear (initialize) the previously stored learning values. Since the multi-mode manual transaxle system does not have an overwrite function, clearing (initializing) stored data is necessary to allow the system to learn.
Do not clear (initialize) parts other than those specified in the "Part installed" column in the table above.

PRECAUTIONS REGARDING USE OF SHIFT LOCK RELEASE BUTTON
When the vehicle is parked with the shift lever in any position other than N:
The engine cannot be started if the shift lever is moved to a position other than N by operating the shift lock release button.
The shift lever should be moved back to N to start the engine.
The engine cannot be started if the shift lever is in the position it was in when the vehicle was parked.
The shift lever should be moved back to N to start the engine.
If the shift lever is returned to N by operating the shift lock release button, turning the ignition switch to ON with the brake pedal depressed will shift the gear to neutral, so that the engine can be started.
When the vehicle is parked with the shift lever in the N:
The engine can be started even if the shift lever is moved to a position other than N by operating the shift lock release button. In this case, the gear is shifted to the position in accordance with the shift lever position after the engine starts.
| Shift Lever Position when Vehicle Parked | Current Shift Lever Position | Engine Cranking Operation | Note |
|---|---|---|---|
| Other than N | Other than N* | Impossible | - |
| Other than N | Same position as when vehicle parked | Impossible | - |
| Other than N | N* | Possible | Gear shifted to neutral when ignition switch is ON with brake pedal depressed |

Possible | - |
*: The shift lever was moved with the shift lock release button operation.
PRECAUTION REGARDING USE OF INTELLIGENT TESTER
Note
Observe the following items for safety reasons:
Read its instruction books before using the tester.
Prevent the tester cable from being caught on the pedals, shift lever and steering wheel when driving with the tester connected to the vehicle.
When driving the vehicle for testing purposes using the tester, two people are required. One drives the vehicle, and the other operates the tester.
MALFUNCTION RECORD
Even if a system error occurs, the TCM may stop the system and store the history record without outputting a DTC and without illuminating the multi-mode transaxle warning light. This historical data can be seen under "Protection Hist" (Protection History) on the data monitor. If the DTC is cleared, the historical data will also be cleared Click here.
