System Description [03/2017 - ]
- UNLOCK OPERATION CONDITIONS FOR STEERING LOCK
- When any of the following condition are met, the unlock operation is performed:
- Vehicle is stopped.
- Matching code is detected in vehicle interior.
- The engine switch pressed: off → on (ACC) or on (IG)
- When any of the following conditions are met, key verification is performed.
- 30 seconds elapse after opening and closing a door.
- The engine switch is pressed.
- The brake pedal*1 or clutch pedal*2 is depressed so that the engine can be started.
- *1: for Automatic Transmission
- *2: for Manual Transmission
HINT:
- Key verification occurs when the code emitted from the key and the code calculated by the certification ECU (smart key ECU assembly) are compared to check that they match.
- Certification ECU (smart key ECU assembly) verification occurs when the S code and L code are verified while the engine is being started or the engine switch is being pushed. The S code is used for certification between the ID code box (immobiliser code ECU) and the certification ECU (smart key ECU assembly). The L code is used for certification between the ID code box (immobiliser code ECU) and the steering lock actuator assembly (steering lock ECU).*1
- Certification ECU (smart key ECU assembly) verification occurs when the L code is verified while the engine is being started or the engine switch is being pushed. The L code is used for certification between the certification ECU (smart key ECU assembly) and the steering lock actuator assembly (steering lock ECU).*2
- *1: w/ ID Code Box
- *2: w/o ID Code Box
- When any of the following condition are met, the unlock operation is performed:
- LOCK OPERATION CONDITIONS FOR STEERING LOCK
- When all of the following conditions are met and the certification ECU (smart key ECU assembly) has been verified, the lock operation is performed.
- The engine switch is off.
- The shift lever is in P*.
*: for Automatic Transmission
- Any door is closed and then opened or a door lock operation (entry door lock or wireless door lock) is performed.
- When all of the following conditions are met and the certification ECU (smart key ECU assembly) has been verified, the lock operation is performed.
- INDICATOR FUNCTION
- The entry key indicator blinks in yellow indicating a malfunction is present when one of the following occurs: 1) A vehicle speed information malfunction (vehicle speed mismatch) is detected, 2) a malfunction which may result in the steering lock not operating correctly is detected (however, the steering lock operates properly), or 3) a malfunction in the IG control circuit (hold circuit) is detected. If a malfunction which results in the indicator blinking in yellow occurs, the engine cannot be started once it is turned off.
HINT:
DTCs are stored in all cases listed above.
- The entry key indicator blinks in yellow indicating a malfunction is present when one of the following occurs: 1) A vehicle speed information malfunction (vehicle speed mismatch) is detected, 2) a malfunction which may result in the steering lock not operating correctly is detected (however, the steering lock operates properly), or 3) a malfunction in the IG control circuit (hold circuit) is detected. If a malfunction which results in the indicator blinking in yellow occurs, the engine cannot be started once it is turned off.
- STEERING LOCK ACTUATOR ASSEMBLY (STEERING LOCK ECU) DESCRIPTION
- The steering lock ECU is built into the steering lock actuator assembly of the steering column assembly.
- The steering lock actuator assembly (steering lock ECU) is not connected to the CAN communication system. However, the steering lock actuator assembly (steering lock ECU) is connected to the certification ECU (smart key ECU assembly) via LIN communication and communicates with other components via CAN communication through the certification ECU (smart key ECU assembly).
