2. Remove the following parts:
(1) Rear package tray (See REAR PACKAGE TRAY REMOVAL/INSTALLATION.)
(2) Trunk covering (See TRUNK COVERING REMOVAL/INSTALLATION.)
(3) Trunk board (See TRUNK BOARD REMOVAL/INSTALLATION.)
(4) Trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)
3. Partially peel back the trunk side trim (RH) to the position allowing removal of the keyless receiver.(See TRUNK
SIDE TRIM REMOVAL/INSTALLATION.)
4. Disconnect the connector from the keyless receiver.
5. Remove the keyless receiver. (See KEYLESS RECEIVER REMOVAL/INSTALLATION.)
6. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)
7. Reconnect the connector.
8. Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).
• If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection
item(s) and related wiring harnesses.
― If the system does not operate normally even though the parts under Inspection Item(s) and related wiring
harnesses do not have any malfunction, replace the keyless receiver. (See KEYLESS RECEIVER

(2) Trunk covering (See TRUNK COVERING REMOVAL/INSTALLATION.)
(3) Trunk board (See TRUNK BOARD REMOVAL/INSTALLATION.)
(4) Trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)
2. Partially peel back the trunk side trim (LH) to the position allowing removal of the theft-deterrent siren.(See
TRUNK SIDE TRIM REMOVAL/INSTALLATION.)
3. Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).
• If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection
item(s) and related wiring harnesses.
― If the system does not work normally even though the parts or related wiring harnesses do not have any
malfunction, replace the theft-deterrent siren. (See THEFT-DETERRENT SIREN REMOVAL/
