What Does B1514 Mean?
B1514 indicates the Body Control Module (BCM) has detected a fault in the Driver Information Center (DIC) switch circuit. This code is triggered when the BCM detects an open circuit, short circuit, or abnormal resistance in the wiring or switch assembly that allows the driver to navigate menus and settings on the instrument cluster display. The fault prevents proper communication between the DIC control switches and the BCM, potentially disabling user interface functions.
Common Causes
45%
Faulty DIC control switch assembly with worn contacts or internal failure
30%
Open or short circuit in wiring harness between DIC switch and BCM
15%
Corroded or loose electrical connectors at switch or BCM
10%
Failed Body Control Module with internal circuit fault
Diagnostic Steps
1
Step 1: Perform visual inspection of DIC switch assembly and steering wheel controls for physical damage, loose mounting, or signs of moisture intrusion. Check all accessible connectors for corrosion, pushed-back pins, or loose connections.
2
Step 2: Using a digital multimeter, backprobe the DIC switch connector and verify proper ground circuit continuity (should read less than 0.5 ohms to chassis ground) and check for battery voltage on power supply wire with ignition on.
3
Step 3: Test DIC switch operation by measuring resistance across switch terminals while pressing each button. Compare readings to manufacturer specifications (typically varies from 0 ohms to several thousand ohms depending on button pressed).
4
Step 4: Check continuity of signal wires between DIC switch connector and BCM connector with harness disconnected at both ends. Resistance should be less than 1 ohm. Also check for shorts to ground or power (should read infinite resistance).
5
Step 5: If all wiring and grounds are intact, substitute a known-good DIC switch assembly and clear codes. Test operation through all menu functions to verify repair.
6
Step 6: If fault persists after switch replacement, perform BCM voltage and ground verification, then suspect internal BCM failure requiring module replacement and programming.

The most common cause of B1514 (Driver Information Center (DIC) Switch Circuit) is: Faulty DIC control switch assembly with worn contacts or internal failure
Typical repair costs for B1514 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive as this code only affects convenience features like menu navigation and display settings. Repair is not urgent but should be addressed to restore full functionality of the driver information system.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B1514 to identify the root cause.
