Diagnostic Fault Information






Circuit/System Description

S11 is part of the Rear Compartment Lid Release Switch - Front Hinge - Left assembly. The folding top control (FTC) module uses S11 to determine if the left side of the deck lid is in a reverse open position. S11 is closed and pulls the signal circuit low when the deck lid is in a reverse open position during top operation.

Conditions for Running the DTC

The FTC module is operational.

Conditions for Setting the DTC

An open or short to ground is detected on the signal circuit of S11.

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.

Diagnostic Aids

* An open or high resistance on the low reference circuit may also cause a DTC B366A 59 to set.
* A weak battery may cause DTC B366B 59 to set.
* A short to B+ may damage S11.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at S11.
2. Ignition ON, verify the scan tool LF RCL Unlatched Switch parameter is Inactive.

• If not the specified value, test the signal circuit terminal B for a short to ground. If the circuit tests normal, replace the FTC module.

3. Connect a fused jumper wire between the signal circuit terminal B and ground.
4. Verify the scan tool LF RCL Unlatched Switch parameter is Active.

• If not the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the FTC module.

5. Test the signal circuit of S11 for a short to voltage. If the circuit tests normal, replace S11
