1. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2. Remove the following parts:

(1) Trunk board (See TRUNK BOARD REMOVAL/INSTALLATION.)

(2) Bass-box (with Bose®) (See BASS-BOX REMOVAL/INSTALLATION.)

(3) Sub-trunk (See SUB-TRUNK REMOVAL/INSTALLATION.)

(4) Trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)

3. Remove the keyless receiver with the connector still connected. (See KEYLESS RECEIVER REMOVAL/INSTALLATION.)

4. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

5. 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.
