1.  Remove the following parts:

(1)  Selector lever knob (AT) (See AUTOMATIC TRANSMISSION SHIFT MECHANISM REMOVAL/INSTALLATION.)
(2)  Shift lever knob (MT)
(3)  Shift panel assembly (See SHIFT PANEL REMOVAL/INSTALLATION.)
(4)  Upper panel (See UPPER PANEL REMOVAL/INSTALLATION.)
(5)  Parking brake lever boot panel(See PARKING BRAKE LEVER BOOT PANEL REMOVAL/INSTALLATION.)
(6)  Rear console (See REAR CONSOLE REMOVAL/INSTALLATION.)
(7)  Scuff plate (See SCUFF PLATE REMOVAL/INSTALLATION.)
(8)  Wind blocker (See WIND BLOCKER REMOVAL/INSTALLATION.)
(9)  Front seat back bar garnish (See SEAT BACK BAR GARNISH REMOVAL/INSTALLATION.)
(10)  Quarter trim (See QUARTER TRIM REMOVAL/INSTALLATION.)
(11)  Tire house trim (See TIRE HOUSE TRIM REMOVAL/INSTALLATION.)
(12)  Back trim (See BACK TRIM REMOVAL/INSTALLATION.)

2.  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 inspection items are normal, replace the retractable hardtop control module.
