Diagnostic Fault Information
Circuit/System Description
The folding top uses electronically controlled valves to control the flow of hydraulic fluid. The folding top control (FTC) module controls Valve 2 (V2) by supplying voltage to the valve. The FTC Module also monitors the control circuit of V2 for proper operation.
Conditions for Running the DTC
The FTC module is active.
Conditions for Setting the DTC
B3675 01
A short to voltage on the control circuit of V2.
B3675 02
A short to ground on the control circuit of V2.
B3675 04
An open on the control circuit or low reference circuit of V2.
Action Taken When the DTC Sets
The top is disabled.
Conditions for Clearing the DTC
The fault is no longer present and the top completes one cycle.

Circuit/System Testing
B3675 01
Test the control circuit of V2 for a short to voltage. If the circuit test is normal, replace the FTC module.
B3675 02
Test the control circuit of V2 for a short to ground. If the circuit test is normal, replace the FTC module.
B3675 04
1. Ignition OFF, disconnect the harness connector at V2.
2. Test for less than 5.0 ohm between the low reference circuit terminal 2 and ground.
• If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the FTC module.
3. Connect a test lamp between the control circuit terminal 1 and ground.
4. Ignition ON, command V2 on with a scan tool. The test lamp should illuminate.
• If the test lamp does not illuminate, test the control circuit for an open/high resistance. If the circuit tests normal, replace the FTC module.
5. If all circuits test normal, replace V2.
