INSPECTION
1. INSPECT WIRELESS DOOR LOCK TRANSMITTER
a. Using a screwdriver, remove the cover.
b. Remove the lithium battery (lithium battery).
c. Install a new or normal battery (lithium battery).
HINT: When a new or normal battery can not be obtained, connect 2 new 1.5 V batteries in series, connect the battery (+) to the battery receptacle side terminal and the battery (-) to the bottom terminal, then apply 3 V voltage to the transmitter.
d. In the location where transmitter is approx. 1 M away from the driver's outside handle in the right direction, check transmitter operation while pressing transmission switch on the side of the transmitter body.
Standard: Remote control of the vehicle door lock can be operated.
HINT:
- The minimum operation distance differs according to operator, the way of holding the transmitter, and location.
- As a weak wave is used, operating distance might be shortened when noise is detected in a strong wave or a used frequency.
e. Install the lithium battery (lithium battery).
f. Install the cover so that a rubber cover is not distorted or slipped off.
