No

Repair or replace the wiring harness.

5

• Turn the ignition switch to the LOCK position.

• Disconnect the negative battery cable.

• Disconnect the power retractable hardtop control module connector.

• Inspect for continuity between power retractable hardtop control module terminal 2E and body ground, and terminal 2F and body ground.

• Is there continuity?

Yes

Go to the next step.

No

Repair or replace the wiring harness.

6

• Disconnect the roof/deck panel motor connector.

• Disconnect the power retractable hardtop control module connector.

• Inspect the following wiring harnesses for an open or short circuit.

• Between power retractable hardtop control module connector terminal 3A and roof motor connector (RH) terminal E, and between power retractable hardtop control module connector terminal 3I and roof motor connector (RH) terminal A

• Between power retractable hardtop control module connector terminal 3H and deck panel motor connector (LH) terminal A, and between power retractable hardtop control module connector terminal 3P and deck panel motor connector (LH) terminal E

• Between power retractable hardtop control module connector terminal 3M and deck panel motor connector (RH) terminal A, and between power retractable hardtop control module connector terminal 3E and deck panel motor connector (RH) terminal E

• Is the wiring harness normal?

Yes

Go to the next step.

No

Repair or replace the wiring harness.

7

• Disconnect the roof/deck panel motor connector.

• Disconnect the power retractable hardtop control module connector.

• Inspect the sensor power supply wiring harness for an open or short circuit.

• Power retractable hardtop control module connector terminal 1G—Roof motor connector (RH) terminal B

• Power retractable hardtop control module connector terminal 1G—Roof motor connector (LH) terminal B
