Power Locks: Description and Operation
GENERAL INFORMATION
OPERATION
CENTRAL DOOR LOCKING SYSTEM
The central door locking system operates the door lock actuator to lock or unlock the doors using the operation of the door lock switch built into the front power window (main or sub) switch. The system has the following operations and features.
- All doors can be locked using the door lock switch built into the front power window (main or sub[ RH]) switch.
CENTRAL DOOR LOCKING
- All the doors can be locked/unlocked, using the driver's side door lock switch or the passenger's side door lock switch.
- The function that allows the driver's door to be opened by pulling the driver's door inside handle even when the driver's door inside lock knob is in the lock position is called "override function".
-
When the door is locked by the driver's or passenger's door lock switch, the ETACS-ECU operates its door lock relay and passes a current through the door lock actuators of all the doors for 0.25 second to lock all the doors.
When the door is unlocked by the driver's or passenger's door lock switch, the ETACS-ECU operates its door unlock relay and passes a current through the door lock actuators of all the doors for 0.25 second to unlock all the doors.
When the door is locked and unlocked by driver's or passenger's door lock switch consecutively, the ETACS-ECU operates its door lock relay and passes a current through the door lock actuators of all the doors for 0.25 second to lock all the doors. Then, the ETACS-ECU operates its door unlock relay and passes a current through the door lock actuators of all the doors for 0.25 second to unlock all the doors. Due to this, there may be a time lag between the driver's or passenger's door lock switch actuation and the time when all the doors are unlocked.
SELECTOR "P" POSITION-LINKED DOOR UNLOCKING FUNCTION[ TC-SST]
- When the selector lever is shifted to the "P" (parking) position with the ignition switch turned ON, all the doors will be unlocked automatically, improving passengers' convenience for getting out. Using a customization feature, the selector "P" position-linked door unlocking function can be switched (Refer to Programming and Relearning ).
-
When the selector lever is shifted to the P position with the ignition switch turned ON, the lever position sensor "P" turns ON, ETACS-ECU turns the unlock relay output ON for 0.25 second to unlock all the doors.
IGNITION SWITCH "LOCK (OFF)" POSITION-LINKED DOOR UNLOCKING FUNCTION[ M/T, TC-SST]
- When the ignition switch is turned to the " LOCK (OFF)" position, all the doors will be unlocked automatically, improving passengers' convenience for getting out. Using a customization function, the ignition switch " LOCK (OFF)" position-linked door unlocking function can be changed (Refer to Programming and Relearning ).
-
When the ignition switch is turned to the " LOCK (OFF)" position, ETACS-ECU turns the unlock relay output ON for 0.25 second to unlock all the doors.
POWER WINDOWS
When the power window (main or sub) switch is operated, the door windows will open or close. This system has the following operations and features.
- There is a power window lock switch featured on the power window main switch to prevent the door window glass from opening/closing with the front passenger's and rear power window sub switch.
- The power window of the door window glass can be opened/closed for 30 seconds with the timer function after the ignition switch is turned OFF (The timer expires if the driver's or front passenger's door is opened when the timer is in operation).
- The power window main switch contains a one-touch down/up switch that will automatically open/close driver's side door window only.
SAFETY MECHANISM (DRIVER'S DOOR ONLY)
- The power window with the safety mechanism has been adopted to enhance safety. If any obstacle such as a hand or a head is detected to be pinched during a door window glass closing operation, the door window glass is opened by approximately 150 mm (6.0 inches). The safety mechanism is activated when the power window switch is operated by one-touch closing operation (the status when the hand is released from the switch knob after one-touch closing operation).
- To prevent anyone from intruding into the vehicle, by performing the manual-closing operation of the power window switch, or by continuing the one-touch closing operation (keep pulling up the switch knob), the door window glass can be forcibly closed without safety mechanism activation even when the obstacle is detected to be pinched.
- When the power window switch manual-closing or one-touch closing operation is performed accidentally, and an obstacle is detected, the power window switch manual-closing and one-touch closing operations are prohibited for 3 seconds after the obstacle has been detected to be pinched, and activates the safety mechanism.
POWER WINDOW TIMER FUNCTION
Even after the ignition is switched off, the ETACS-ECU keeps the power window relay activated for approximately 30 seconds, enabling raising or lowering of the power windows by using the power window switches (timer function). After approximately 30 seconds, the power window relay is deactivated.
During this timer operation, if the driver's or front passenger's door is opened, the power window relay is deactivated from that moment.
