The remote function receiver module receives a signal from the keyless entry transmitters when a button is pressed; it then sends the request to the BCM.
The BCM detects an invalid message from the remote function receiver module; a message with a parity error. This indicates an internal fault within the remote function receiver module.
No action is taken.
| • | A current DTC will clear when the fault is no longer present and the ignition switch is cycled. | 
| • | The history DTC will clear after 100 consecutive ignition cycles without a fault present. | 
| • | A scan tool may be used to clear history and current DTCs. |
