Tonneau Cover Sensor Faults
Refer to Wiring Diagrams Cell 103 for schematic and connector information.
Normal Operation and Fault Conditions
A tonneau cover sensor is hardwired to the Moveable Roof Control Module A (MRCMA) and a separate tonneau cover sensor is hardwired to the Moveable Roof Control Module B (MRCMB). Each module sends out a 5 volt reference signal to the respective Hall-effect switch and receives a voltage signal input from the switch when the tonneau cover is installed. When a tonneau cover sensor or circuit is faulted, the convertible top may open, but does not close. Also, depending on the nature of the fault, the message center may display the TOP DISABLED - REMOVE COVERS.
DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
B1070:12 Tonneau Lid Piston Out Sensor: Circuit Short To Battery | This DTC sets if the tonneau cover sensor voltage signal sent to the Moveable Roof Control Module A (MRCMA) or Moveable Roof Control Module B (MRCMB) is shorted to battery voltage. | |
B1070:14 Tonneau Lid Piston Out Sensor: Circuit Short To Ground or Open | This DTC sets if the tonneau cover sensor voltage signal sent to the Moveable Roof Control Module A (MRCMA) or Moveable Roof Control Module B (MRCMB) is shorted to ground or open. | |
B1070:29 Tonneau Lid Piston Out Sensor: Signal Invalid | This DTC sets if the Moveable Roof Control Module A (MRCMA) or Moveable Roof Control Module B (MRCMB) or receives an implausible signal from the tonneau cover sensor. |
