What Does B1469 Mean?
B1469 indicates the Body Control Module (BCM) has detected an open circuit in the chime input request signal circuit. This code means the BCM is not receiving proper electrical continuity from components that request audible chime alerts (such as door ajar switches, key-in-ignition sensors, seatbelt reminders, or turn signal indicators). The open circuit prevents the BCM from knowing when to activate the warning chime, resulting in missing or non-functional audible alerts.
Common Causes
40%
Broken or damaged wiring in the chime request circuit between input devices and BCM, including corroded or loose connections at harness connectors
30%
Faulty door ajar switch or key-in-ignition switch with open internal contacts or disconnected wiring
20%
Failed Body Control Module with internal circuit damage or software corruption affecting chime input monitoring
10%
Blown fuse or open circuit breaker supplying power to chime input circuit components
Diagnostic Steps
1
Step 1: Perform visual inspection of all BCM connectors and wiring harnesses leading to door switches, ignition switch, and chime input devices for obvious damage, corrosion, or disconnected terminals
2
Step 2: Using a digital multimeter, check for continuity between the BCM chime input terminal (consult wiring diagram for specific pin) and ground with all chime-triggering switches in their activated positions (door open, key inserted)
3
Step 3: Test each individual chime input device (door ajar switches, key-in-ignition switch) by measuring resistance across terminals while cycling the switch; should show continuity when activated and infinite resistance when deactivated
4
Step 4: Check power supply to the chime input circuit by verifying voltage at the BCM connector chime input pin with ignition on; should read battery voltage when any chime condition is active
5
Step 5: If all wiring and switches test good, perform BCM voltage supply and ground tests to confirm module has proper power and ground connections on all pins
6
Step 6: Clear codes and test chime function by triggering various chime conditions (open door with key on, leave key in ignition); if chime still non-functional with good wiring, replace BCM
Estimated Repair Cost

The most common cause of B1469 (Chime Input Request Circuit Open) is: Broken or damaged wiring in the chime request circuit between input devices and BCM, including corroded or loose connections at harness connectors
Typical repair costs for B1469 range from $75 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive, but warning chimes will not function to alert driver of doors ajar, keys left in ignition, lights on, or unfastened seatbelts. This increases risk of dead battery or unsafe driving conditions due to missed warnings.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1469 to identify the root cause.
