B1468 Chime Request Circuit Malfunction
The B1468 code indicates that the Body Control Module (BCM) or instrument cluster has detected a fault in the chime request circuit. This circuit carries input signals that trigger warning chimes for conditions like key in ignition, door ajar, seatbelt unbuckled, or lights on. The fault can be an open circuit, short to ground, or short to voltage, preventing the chimes from sounding properly.
1. Commonly Affected Makes
2. Most Common Causes
- Faulty door ajar switch or damaged wiring
- Failing key-in-ignition switch
- Defective seatbelt buckle switch
- Short to ground, short to voltage, or open circuit in wiring between switches and BCM/instrument cluster
- Internal failure of the BCM or instrument cluster
3. Symptoms You Will Notice
- No warning chimes when key is in ignition
- No chime when door is open with key in ignition
- No seatbelt reminder chime
- No lights-on reminder chime
4. Step-by-Step Diagnosis
Scan for related codes and check BCM/instrument cluster data for chime request inputs.
Inspect door ajar, key-in-ignition, and seatbelt buckle switches for proper operation.
Check wiring and connectors for shorts, opens, or corrosion between switches and BCM/cluster.
If wiring and switches are good, test BCM or instrument cluster for internal fault.
5. Frequently Asked Questions
