INSPECT REAR ROOF LINK LIMIT SWITCH (RH) CIRCUIT FOR SHORT TO GROUND
• Switch the ignition off.
• Disconnect the negative battery cable.
• Disconnect the retractable hardtop control module and rear roof link limit switch (RH) connectors.
• Inspect for continuity between the following terminal (wiring harness-side) and body ground:
-
― Rear roof link limit switch (RH) terminal A
• 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 4D and rear roof link limit switch (RH) terminal A
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 7.

INSPECT REAR ROOF LINK LIMIT SWITCH (RH) CIRCUIT FOR OPEN CIRCUIT
• Verify that the retractable hardtop control module and rear roof link motor (RH) connectors are disconnected.
• Inspect the wiring harness for continuity between the following terminals (wiring harness-side):
-
― Retractable hardtop control module terminal 4A and rear roof link limit switch (RH) terminal B
― Retractable hardtop control module terminal 4E and rear roof link limit switch (RH) terminal C
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
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 4A and rear roof link limit switch (RH) terminal B
• Retractable hardtop control module terminal 4E and rear roof link limit switch (RH) terminal C
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 an open circuit.
• 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 7.

|
INSPECT REAR ROOF LINK LIMIT SWITCH (LH) CIRCUIT FOR SHORT TO GROUND
• Disconnect the rear roof link limit switch (LH) connector.
• Verify that the retractable hardtop control module and rear roof link limit switch (LH) connectors are disconnected.
• Inspect for continuity between the following terminal (wiring harness-side) and body ground:
-
― Rear roof link limit switch (LH) terminal A
• 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 4I and rear roof link limit switch (LH) terminal A
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 7.

|
INSPECT REAR ROOF LINK LIMIT SWITCH (LH) CIRCUIT FOR OPEN CIRCUIT
• Verify that the retractable hardtop control module and rear roof link limit switch (LH) connectors are disconnected.
• Inspect the wiring harness for continuity between the following terminals (wiring harness-side):
-
― Retractable hardtop control module terminal 4J and rear roof link limit switch (LH) terminal B
― Retractable hardtop control module terminal 4F and rear roof link limit switch (LH) terminal C
― Retractable hardtop control module terminal 4F and rear roof link limit switch (LH) terminal D
• Is there continuity?
|
Yes
|
Go to the next step.
|
|
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 4J and rear roof link limit switch (LH) terminal B
• Retractable hardtop control module terminal 4F and rear roof link limit switch (LH) terminal C
• Retractable hardtop control module terminal 4F and rear roof link limit switch (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 an open circuit.
• 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 7.
