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 Folding Top Control (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
