DTC DESCRIPTORS

DTC B366A 58
Deck Lid Latched Left Front Sensor Circuit incorrect reaction after event

DTC B366A 59
Deck Lid Latched Left Front Sensor Circuit circuit/component time out

CIRCUIT/SYSTEM DESCRIPTION
S12 is part of the Rear Compartment Lid Release Switch - Front Hinge - Left assembly. The folding top control (FTC) module uses S12 to determine it the left front corner of the rear deck lid is latched. S12 is closed and pulls the signal circuit low when the left front corner of the rear deck lid is latched.

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 S12.

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 B366B 59 to set.
- A weak battery may cause DTC B366A 59 to set.
- A short to B+ may damage S12.

CIRCUIT/SYSTEM TESTING
1. Disconnect S12.
2. Use a scan tool to monitor LF RCL Latched Switch.
3. The scan tool should indicate Inactive.
- If scan tool does not indicate Inactive, test the signal circuit of S12 for a short to ground.
- If circuit OK, replace FTC Module.
4. Connect a fused jumper wire between the signal circuit of S12 and ground.
5. Use a scan tool to monitor LF RCL Latched Switch.
6. The scan tool should indicate Active.
- If scan tool does not indicate Active, Test the signal circuit of S12 for an open or high resistance.
- If circuit OK, replace FTC Module.
7. Test the signal circuit of S12 for a short to voltage. If circuit tests OK, replace S12.
