CONSTRUCTION
Key
The key consists of a mechanical key, transmitter for the wireless door lock control, transceiver for the entry function, and transponder chip for the engine immobiliser function.
This mechanical key operates the driver door lock cylinder, but cannot be used to start the hybrid control system. When the mechanical key is used, the cap of the driver door lock cylinder must be removed.
The transmitter for the wireless door lock control has a LOCK button, UNLOCK button and PANIC button.
The transmitter for the remote air conditioning system control has a remote air conditioning button.
The transceiver of the key receives the signals from the oscillators and returns the ID code to the door control receiver.
The transponder chip for the engine immobiliser function returns a signal to the power switch as a response to the radio wave it received from the power switch.

| *5 | Mechanical Key | - | - |
Power Switch
The power switch consists of a momentary type switch, indicator light (amber and green color LEDs), illumination, antenna coil, and transponder key amplifier.
The driver can determine the present power source and check whether the hybrid control system can start or not in accordance with the illumination state of the indicator light.
When the power management control ECU detects an abnormality with the start system, it makes the amber indicator light flash. If the hybrid control system is stopped in this state, it might not be possible to restart it.
| Power Source Condition | Indicator Light Condition | |
|---|---|---|
| Brake pedal not depressed | Shift position is in P while the brake pedal is being depressed | |
| OFF | OFF | ON (Green) |
| ACC, IG-ON | ON (Amber) | ON (Green) |
| Hybrid control system Running | OFF | |
| Start System Malfunction | Flashes (Green) for 15 seconds | |
DIAGNOSIS
Start Function
The power management control ECU and Certification ECU can detect malfunction in the start system when the power source is in the on (IG).
When the ECUs detect a malfunction, the amber indicator light of the power switch flashes to warn the driver. At the same time, the ECUs store 5-digit Diagnostic Trouble Code (DTC) in their memories.
The indicator light warning continues for 15 seconds even after the power switch is switched to off.
The 5-digit DTCs can be read after connecting an intelligent tester to DLC3.
The entry and start system may not operate successfully if a malfunction occurs.
