B1323

DTC B1323

CIRCUIT DESCRIPTION
The roof door module (RDM) monitors the folding top stowage compartment lid latch switch signal circuits at least once every 200 milliseconds. The retractable roof stowage compartment left and right lid latch switches are wired in series. The folding top stowage compartment lid latch switches are limit switches. When the stowage compartment lid is latched, the limit switches are active. When the limit switches are active, the RDM detects a switched ground signal.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B1323 Tonneau Down and Latched (single or left) Sensor Circuit

CONDITIONS FOR RUNNING THE DTC
- The battery voltage is between 9-16 volts.
- Ignition is in the Accessory or Run position or retained accessory power (RAP) is active.
- A request for folding top operation has been received by the RDM, and the RDM attempts to operate the folding top.

CONDITIONS FOR SETTING THE DTC
- If the RDM detects the folding top stowage compartment lid in the latched position and the folding top stowage compartment lid extend cylinder is fully extended.
- The RDM has performed a folding top stowage compartment lid down command for approximately 30 seconds and the RDM does not detect the folding top stowage compartment lid latched signal.
- An open or high resistance exists in the folding top stowage compartment lid latch switch signal circuit or ground circuit.
- An open, high resistance, or short to ground in the folding top valve 3 battery positive supply voltage circuit and folding top valve 3 control circuit.
- A short to ground in the IGN 0 supply voltage circuit to any valve, relay or motor on that circuit.
- An internally shorted to ground valve or pump motor relay on the IGN 0 supply voltage circuit.

ACTION TAKEN WHEN THE DTC SETS
- Stores a current and history DTC B1323 in the RDM.
- Folding top operation is suspended.
- Message displayed on the Driver Information Display-ROOF CYCLE TIMEOUT.

CONDITIONS FOR CLEARING THE DTC
- This DTC will clear on the current status after the condition for setting the fault is corrected.
- A history DTC will clear after 50 consecutive ignition cycles without a fault present.
- History and current DTC can be cleared using the scan tool.

DIAGNOSTIC AIDS
If the DTC does not reset after the code is cleared, then the switch may be the source of an intermittent fault.
