What Does B2328 Mean?
This code indicates that the Body Control Module (BCM) has detected an electrical fault in the feedback potentiometer circuit for the steering column reach adjustment system. The potentiometer provides position feedback to the control module during powered telescoping adjustment of the steering column. The BCM has identified that the voltage signal from this sensor is out of range, erratic, or absent entirely.
Common Causes
45%
Faulty steering column reach potentiometer with worn resistive track or internal failure
30%
Damaged wiring harness or corroded connector at the reach potentiometer
15%
Poor ground connection in the steering column adjustment circuit
10%
Failed Body Control Module (BCM) with internal circuit damage
Diagnostic Steps
1
Step 1: Perform a visual inspection of the steering column reach adjustment mechanism and wiring harness for obvious damage, chafing, or loose connections. Check connector at the reach potentiometer for corrosion, bent pins, or moisture intrusion.
2
Step 2: Using a digital multimeter, backprobe the potentiometer connector and verify reference voltage (typically 5V) and ground (0V) are present at the sensor connector with ignition on. Document actual voltage readings.
3
Step 3: Monitor the signal voltage output from the potentiometer while manually moving the steering column reach adjustment through its full range of travel. Signal should sweep smoothly between approximately 0.5V and 4.5V without dropouts or spikes.
4
Step 4: If voltage readings are erratic or absent, disconnect the potentiometer and measure its resistance across the signal and ground terminals while moving the adjustment. Resistance should change smoothly without dead spots (typically 1-10k ohms range).
5
Step 5: Check continuity and resistance of all wiring between the potentiometer connector and the BCM connector. Verify ground circuit has less than 0.5 ohms resistance to chassis ground.
6
Step 6: If all wiring and potentiometer test correctly, suspect BCM internal fault. Clear codes, perform BCM relearn/calibration procedure for steering column position, and retest system operation through multiple cycles.

The most common cause of B2328 (Column Reach Feedback Potentiometer Circuit Failure) is: Faulty steering column reach potentiometer with worn resistive track or internal failure
Typical repair costs for B2328 range from $150 to $650, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This fault does not affect steering control or vehicle safety, only the powered reach adjustment feature of the steering column. The vehicle is safe to drive, though manual adjustment may not be available until repaired. Non-urgent repair unless adjustment functionality is required for driver comfort.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2328 to identify the root cause.
