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
