Toyota Highlander Ignition Switch

The Ignition Switch of the Toyota Highlander directs the flow of battery power depending on the position of the key or button. The positions enable starting the engine, using components, and locking out shifting. With the Ignition Switch in start, current is sent to the starter, ignition, and fuel circuits so that the Highlander runs. When the switch is on, current maintains the engine and component power. When the key is switched to acc, the operation of the radio or windows can be performed, and when off is turned, the power supply is stopped. When the key is removed and the steering column is locked, automatic transmission shift interlock mechanisms hold the transmission in park position. A coded key or fob must talk to the Toyota computer before starting the car, reducing the risk of theft. Worn Ignition Switch keys, tumblers, or internal contacts can create a switch that is hard to turn, prevent cranking, or cut off the engine. Proper performance of the Ignition Switch preserves Toyota pathways and keeps the Highlander responsive at every key position. The Ignition Switch has a consistent flow that enables security codes to pass through. As such, a Highlander will not start when a key does not belong or if there is no key.
