B3667
DTC B3667
CIRCUIT DESCRIPTION
The left and right folding top stowage compartment latch cylinder position sensors are hall effect sensors mounted on the folding top stowage compartment latch cylinders. The sensors are supplied with a 12-volt reference signal from the roof door module (RDM). When the folding top stowage compartment latch cylinders are fully retracted, the left and right folding top stowage compartment latch cylinder position sensors will be active sending a voltage signal between 0.35 and 1.33 volts to the RDM. When the folding top stowage compartment lid is in the latched position with the cylinder in the fully extended position, the left and right folding top stowage compartment latch cylinder position sensors will be inactive sending a voltage signal between 2.39 and 4.04 volts to the RDM. The RDM monitors the left and right folding top stowage compartment latch cylinder position sensors at least once every 200 milliseconds.
DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC B3667 Tonneau Release 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 a folding top stowage compartment latch cylinder position sensor signal circuit shorted to power.
- If the RDM detects a folding top stowage compartment latch cylinder position sensor signal circuit shorted to ground or open.
- If the RDM detects the folding top stowage compartment latch cylinder position sensor 12-volt reference is open or shorted to ground.
- If the RDM detects the folding top stowage compartment latch cylinder position sensor signal circuit active and the folding top cylinder retracted signal circuit are active simultaneously.
- If the RDM detects the folding top stowage compartment latch cylinder position sensor signal circuit inactive when the folding top up command has timed out.
ACTION TAKEN WHEN THE DTC SETS
- Stores a current DTC B3667 in the RDM.
- The folding top operation is suspended.
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 sensor may be the source of an intermittent fault.
