What Does B2369 Mean?
This code indicates the Body Control Module (BCM) has detected a short to ground in the chime output circuit. The BCM sends signals to the chime module to produce audible warnings for various vehicle functions (seat belt, key-in-ignition, door ajar, lights on, etc.), and has identified that the output circuit voltage is being pulled to ground when it should not be. This fault prevents proper chime operation and audible safety warnings from functioning correctly.
Common Causes
45%
Damaged or chafed wiring harness causing chime output wire to contact ground or vehicle chassis
30%
Failed chime module with internal short to ground
15%
Corroded or moisture-damaged connector at chime module causing short circuit
10%
Faulty Body Control Module with shorted output driver circuit
Diagnostic Steps
1
Step 1: Perform visual inspection of the chime module and all associated wiring, checking for obvious damage, chafing, pinched wires, or corrosion at connectors. Pay special attention to areas where harnesses pass through firewalls or contact metal body panels.
2
Step 2: Disconnect the chime module connector and use a digital multimeter to measure resistance between the chime output circuit terminal (at the BCM side harness connector) and chassis ground. Reading should be infinite/open circuit; any continuity indicates a short to ground in the wiring harness.
3
Step 3: If wiring tests good, measure resistance across the chime module itself between the input signal terminal and ground terminal with module disconnected. Compare to manufacturer specifications (typically should show high resistance or open circuit when not activated).
4
Step 4: Reconnect chime module and use multimeter in voltage mode to monitor the BCM output signal wire while commanding chime activation via scan tool (if supported). Should see switching voltage (typically 5-12V); constant 0V confirms short to ground.
5
Step 5: If all wiring and chime module test good, suspect BCM internal fault. Check BCM connector for corrosion, moisture, or bent pins. Verify BCM ground connections are clean and tight with less than 0.1 ohm resistance to chassis ground.
6
Step 6: After repairs, clear codes, cycle ignition, and test all chime functions (door ajar, key-in-ignition, seat belt, lights-on) to verify proper operation and confirm code does not return.

The most common cause of B2369 (Chime OUTPUT Request Ckt Short to Ground) is: Damaged or chafed wiring harness causing chime output wire to contact ground or vehicle chassis
Typical repair costs for B2369 range from $100 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive, but important audible safety warnings (seat belt reminder, key-in-ignition, door ajar, lights-on reminder) will not function. This could lead to missed warnings about important vehicle conditions, particularly leaving keys in ignition or headlights on, so repair should be completed promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2369 to identify the root cause.
