Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 10.
5	INSPECT REAR ROOF LINK MOTOR (LH) CIRCUIT FOR SHORT TO GROUND Disconnect the rear roof link motor (LH) connector. Inspect for continuity between the following terminals (wiring harness-side) and body ground: Rear roof link motor (LH) terminal F Rear roof link motor (LH) terminal D Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: Retractable hardtop control module terminal 4U and rear roof link motor (LH) terminal F Retractable hardtop control module terminal 4S and rear roof link motor (LH) terminal D If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to ground. Go to Step 10.
5		No	Go to the next step.
6	INSPECT REAR ROOF LINK MOTOR (LH) CIRCUIT FOR SHORT TO POWER SUPPLY Verify that the retractable hardtop control module and rear roof link motor (LH) connectors are disconnected. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Switch the ignition ON (engine off or on). Measure the voltage at the following terminals (wiring harness-side): Rear roof link motor (LH) terminal F Rear roof link motor (LH) terminal B Is the voltage 0 V?	Yes	Go to the next step.
6		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: Retractable hardtop control module terminal 4U and rear roof link motor (LH) terminal F Retractable hardtop control module terminal 4S and rear roof link motor (LH) terminal B If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
