Causes
- Open or broken wiring in the reach potentiometer circuit
- Disconnected, loose or corroded connector at the steering column
- Failed reach feedback potentiometer (internal open)
- Damaged wiring harness where it flexes in the column or under dash
- Poor ground or 5V reference supply fault from the steering module
- Control module input fault or internal connector fault
Symptoms
- Steering column reach (fore/aft) adjustment will not operate or is intermittent
- Steering column may be stuck in one position
- Occupant display may show column fault or service message
- Relevant steering/comfort functions disabled
- Stored B2329 fault code and possibly related steering or module codes
What to check
- Retrieve and record DTC(s) and freeze frame data with a capable scan tool
- Attempt reach adjustment while monitoring live data for reach potentiometer signal
- Visually inspect connectors at the steering column for corrosion, damage or water ingress
- Inspect wiring harness along the column and under dash for chafing, pinching or breaks
- Check fuses and power/ground circuits related to the steering module
- Perform a wiggle test on column wiring while observing live data or DTC status
Signal parameters
- Reference supply typically 5.0 V from control module (verify)
- Expected potentiometer signal ~0.5–4.5 V depending on column position; ~2.5 V mid-position
- Open-circuit: infinite resistance between signal and reference/ground or no signal voltage
- Typical potentiometer resistances vary; many are in 2–20 kΩ range (manufacturer-specific)
Diagnostic algorithm
- Connect a diagnostic scanner; confirm B2329 and note any additional codes and freeze frame data
- Using live data, observe reach potentiometer signal while operating the reach motor. Note if signal is absent or static.
- Visually inspect the potentiometer connector at the steering column for corrosion, bent pins or water entry. Repair or reseal as needed.
- Check fuses and supply/ground to the steering module. Backprobe the potentiometer connector: verify 5 V reference present, ground continuity, and signal voltage while moving the column.
- If no reference present, trace wiring back to the steering module and repair open/shorts. If reference present but signal is open, check continuity of the signal wire to the module.
- Measure resistance across the potentiometer terminals (with connector disconnected) while moving the column; look for open circuit, dead spots or erratic change.
- Perform a wiggle test of the harness while monitoring signal and DTCs to locate intermittent wiring faults.
- Repair or replace the harness, connector, or potentiometer as required. After repairs, clear codes and confirm correct operation and that the DTC does not return.
- If wiring and sensor check good and signal still absent at module input, consider module input circuit fault and refer to module diagnostics or replacement procedures.
Likely causes
- Broken/shorted/open wire between reach potentiometer and steering module
- Connector unseated or corroded at the steering column
- Failed/open potentiometer inside steering column
- Wiring damage from column movement or previous repairs
- Faulty steering column control module (less likely)
Fault status
Status
Open circuit detected in steering column reach feedback potentiometer circuit. Reach position signal missing or out of range; reach adjustment may be inoperative.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
