Audible Warnings Description and Operation
The audible warnings alert the driver of a system concern or a critical vehicle condition. The instrument panel cluster (IPC) generates audible warnings through an internal acoustic speaker. The IPC receives audible warning requests via the serial data circuit. If the IPC receives multiple audible warning requests, the warning with the highest priority sounds first. The following lists the audible warning priority and the pulse rate:
Fast rate chime (200 pulses per minute)
Medium rate chime (150 pulses per minute)
Slow rate chime (50 pulses per minute)
Single chime
Door Ajar Warning
The IPC activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The door ajar warning sounds and the appropriate DOOR AJAR indicator illuminates in the driver information center (DIC) when the following occurs:
• The body control module (BCM) determines that a door, driver door, passenger door. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The vehicle is not in park. The IPC receives a serial data message from the BCM indicating the gear position.
• The vehicle speed is greater than 8.05 km/h (5 MPH). The IPC uses the vehicle speed information from the ECM to calculate the vehicle speed.
Fasten Safety Belt Warning
The IPC activates the fasten safety belt audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The fasten safety belt warning sounds and the fasten safety belt indicator illuminates when the following occurs:
• The ignition switch transitions to ON.
• The inflatable restraint sensing and diagnostic module (SDM) detects that the driver's seat belt is not buckled. The IPC receives a serial data message from the SDM indicating the drivers seat belt status.
If the seat belt is buckled when the ignition is turned ON, the chime will not sound. If the seat belt is buckled while the chime is sounding, the chime will stop. If the seat belt is unbuckled after the initial transition to ON, the chime will not sound.
Key-In-Ignition Warning
The IPC activates the key-in-ignition audible warning as requested by the BCM. The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The key-in-ignition warning sounds when the following occurs:
• The ignition switch is OFF.
• The body control module (BCM) determines that the driver's door is open. The IPC receives a serial data message from the BCM indicating the door ajar status.
• The BCM determines that the key-in-ignition switch is closed and the signal circuit is low. The IPC receives a serial data message from the BCM indicating the key-in-ignition status.
Lights On Warning
The IPC activates the lights on warning as requested by the body control module (BCM). The BCM sends a serial data message to the IPC indicating the chime frequency and duration. The lights on warning sounds when the following occurs:
• The ignition is OFF.
• The BCM determines that the drivers door is open and the signal circuit is low.
• The BCM determines that the headlamp switch is in the park or head position.
Park Brake Warning

Warning you to turn off the lights and save your battery

Some vehicles have just a standard ignition chime indicating the key is in the ignition. If the sound doesn't turn off in about five chimes you may have a problem with the Chimer of that is if you have no lights on indicating anything.

Sounds like a problem with the sensor in the driver's door latch.

Disconnecting the battery erases stored memory,after you connect the battery put the key in the ignition cylinder and turn the driver door switch on(open) and off (closed), on (open),the entry,exist function then becomes complete, and the return operation can be operated,

Audible Warnings
The body control module (BCM) will provide an audible warning for various events relating to the vehicle. The functions that provide an audible warning are the key in ignition, the lights on, the occupant restraint (seat belt) and the park brake.
Key in the Ignition Audible Chime
The BCM will provide an audible chime if the key is left in the ignition in either OFF or the accessory position with the driver's door open. The chime rate for this is 150 chimes per minute. The key in the ignition chime has a higher priority than the lights on chime.
Lights on Audible Chime
The BCM will provide an audible chime if the park lights are on and the driver's door is open. In addition, 1 or 2 other conditions exist. The key is out of the ignition, or the key is in the ignition in the OFF position, and has not been turned. The BCM will chime at a rate of 200 chimes per minute until the conditions are removed.
Occupant Restraint Audible Chime
The BCM will provide an audible chime based on the class II message received from the SDM if the driver's seat belt is not buckled when the ignition is turned to run or crank. The chime rate for this feature is 50 chimes per minute.
Park Brake Audible Chime
The BCM will provide an audible chime for park brake when the park brake is applied and the vehicle speed is higher that 3 mph. The chime rate for this feature is 200 chimes per minute.

You can't disconnect anything . The problem has to be fixed .

The BCM will provide an audible chime for park brake when the park brake is applied and the vehicle speed is higher that 3 mph. The chime rate for this feature is 200 chimes per minute.

Telltale Chimes
The body control module (BCM) will provide 4 chimes for each telltale activation per ignition cycle, at a rate of 150 or 200 chimes per minute. The chimes are limited to 1 chime event per telltale for each ignition cycle. The power up telltale function will not activate the telltale chime function. If the telltale becomes active during a cycle then the chime will sound.
The following telltales will activate the chime function:
• Low Washer Fluid
• Change Oil Soon Indicator
• Brake Fluid Low
• Oil Pressure Low
• Coolant Temperature Hot
• Low Coolant Level
• Low Fuel Level
• Antilock Brake System
• Volts Light (Generator)
• Supplemental Inflatable Restraint System (Air Bag)
• Trunk or Hatch Ajar

Having the vehicle checked for DTC'S - diagnostic trouble code's in the BCM would be the first step in the diagnostic procedure .
DTC B2965
When the ignition key is seated in the ignition switch, the key-in-ignition switch contacts the close, grounding circuit 80. The body control module (BCM) monitors the state of the key-in-ignition switch, the state of the ignition switch (OFF, ACC, or RUN) and the driver's door to control the key-in-ignition chime.

on some vehicles the chime for the headlights is the same as the chime for the doors, if you have your interior light turned off via switch or just a bad door jamb switch then the headlight chime may not work. at least that's why my dodge quit chiming.
