SMART KEY SYSTEM CHECK
DURING PDS
Models:
'08 Avalon
July 2, 2007
Introduction
Some 2008 model year Avalon vehicles are equipped with a Smart Key system, which allows the customer to enter and start the vehicle without using a mechanical key. To ensure the system is operating properly, the Smart Key functions (Smart Entry and Smart Start) should be inspected during Pre-Delivery Service (PDS). The following inspection procedure has been developed to confirm the proper operation of the Smart Key system prior to vehicle delivery.
NOTE:
Check all of the Smart Keys using this TSB.
Applicable Vehicles
^ 2008 model year Avalon vehicles equipped with the Smart Key System.

Warranty Information
Inspection Procedure
1. Remove ALL Smart Keys from the vehicle.
The remaining keys need to be a minimum of 1 meter (3 feet) away from the vehicle.
2. Check Smart Entry function at all the doors.

NOTE:
Registered Smart Key MUST be in actuation area No.1 for this check (see illustrations).
A. Locking operation:
Push the lock button on the outside door handle. All the doors should lock simultaneously. At this time, one beep will be heard and the turn signal lights will flash once.
B. Unlocking operation:

After checking the lock function, wait at least 3 seconds before checking the unlock function.
Grasp the outside door handle (sensors are located on the underside of the door handles). At this time, two beeps will be heard and the turn signal lights will flash twice.
NOTE:
Only the driver's door unlocks when the driver's door handle is grasped. All the doors unlock when any door handle other than the driver's door handle is grasped.
3. Check the Wireless Door Lock function.
Using the remote outside of the vehicle, confirm that all doors can be locked and unlocked using the wireless remote.
4. Check Smart Start function from inside the vehicle.

NOTE:
Registered Smart Key must be in actuation area No.2 for this check (see illustrations below).

A. Check for proper activation of the "ENGINE START/STOP" switch.
a. Make sure the gear selector lever is in the "P" position.
b. Without depressing the brake pedal, press the "ENGINE START/STOP" switch and confirm the mode changes properly.
From the "OFF" mode:
^ Press once. The power supply mode is in the "ACC" mode.

b. When depressing the brake pedal, check that the green engine switch illuminator comes on, and push the "ENGINE START/STOP" switch to start the engine.
c. Push the switch again to stop the engine.
NOTE:
When the "ENGINE START/STOP" switch is turned OFF with the gear selector lever in a position other than "P" the vehicle electrical system will be in the "ACC" mode. When the door is opened the Smart Key System Warning Buzzer will sound indicating that the electrical system is not "OFF" when exiting the vehicle. This may result in a discharged battery. Be sure to turn OFF the engine AFTER shifting the gear selector lever to the "P" position.
