DTC Descriptors

DTC B366E 58: Deck Lid Unlatched Right Front Sensor Circuit incorrect reaction after event

DTC B366E 59: Deck Lid Unlatched Right Front Sensor Circuit circuit/component protection time out

Circuit/System Description

S9 is part of the Rear Compartment Lid Release Switch - Front Hinge - Right assembly. The folding top control (FTC) module uses S9 to determine if the right side of the deck lid is in a reverse open position. S9 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 S9.

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
    • A short to B+ may damage S9.
    • A weak battery may cause DTC B366E 59 to set.
    • An open or high resistance on the low reference circuit may cause a DTC B366D 59 to also set.

Circuit/System Testing
  1. Disconnect S9.
  2. Use a scan tool to monitor RF RCL Unlatched Switch.
  3. The scan tool should indicate Inactive.
    4. ⇒If scan tool does not indicate Inactive, test the signal circuit of S9 for a short to ground.
    ⇒If circuit OK, replace FTC Module.
  4. Connect a fused jumper wire between the signal circuit of S9 and ground.
  5. Use a scan tool to monitor RF RCL Unlatched Switch.
  6. The scan tool should indicate Active.
    7. ⇒If scan tool does not indicate Active, Test the signal circuit of S9 for an open or high resistance.
    ⇒If circuit OK, replace FTC Module.
  7. Test the signal circuit of S9 for a short to voltage. If circuit tests OK, replace S9.
