What Does B2330 Mean?
This code indicates the Body Control Module (BCM) has detected a short to battery voltage in the steering column reach adjustment feedback potentiometer circuit. The potentiometer is used to provide position feedback for the power telescoping steering column feature. The BCM detected an abnormally high voltage on the signal wire, indicating it is being exposed to battery voltage when it should read a lower reference voltage.
Common Causes
45%
Damaged or chafed wiring harness causing short to power wire in steering column area
30%
Failed reach adjustment potentiometer with internal short to power
15%
Corroded or damaged connector at potentiometer causing cross-circuit short
10%
BCM internal fault with voltage sensing circuit malfunction
Diagnostic Steps
1
Step 1: Perform visual inspection of steering column wiring harness for visible damage, chafing, pinch points, or signs of wire insulation damage near moving components and tilt/telescoping mechanisms
2
Step 2: Disconnect the reach adjustment potentiometer connector and measure voltage on the signal wire at the BCM side using a digital multimeter - should read 0V with ignition on if wire is shorted to battery, or appropriate reference voltage (typically 5V) if circuit is intact
3
Step 3: With potentiometer disconnected, check resistance between signal wire and battery positive using multimeter in ohms mode - reading less than 10k ohms confirms short to battery in wiring harness
4
Step 4: If wiring tests normal, connect ohmmeter to potentiometer component terminals and check for proper resistance sweep (typically 1k-10k ohms) while manually moving reach mechanism - erratic readings or direct short indicates failed potentiometer
5
Step 5: Inspect potentiometer connector terminals for corrosion, pushed-back pins, or moisture intrusion that could cause cross-circuit contact between signal and power pins
6
Step 6: After repairs, clear codes, cycle steering column reach adjustment through full range of motion multiple times, and verify code does not return and position feedback operates correctly

The most common cause of B2330 (Column Reach Feedback Potentiometer Circuit Short to Battery) is: Damaged or chafed wiring harness causing short to power wire in steering column area
Typical repair costs for B2330 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving as this only affects power telescoping steering column adjustment feature, not steering function itself. Repair at convenience to restore comfort adjustment functionality.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2330 to identify the root cause.
