Causes

Faulty column adjustment switch (worn, stuck, internal short/open)
Damaged, corroded, or loose connector at switch or module
Broken/shorted wiring or chafed insulation between switch and control module
Blown fuse or related power/ground supply fault
Steering column mechanical obstruction or damaged actuator
Faulty body/control module or software fault

Symptoms

Column adjustment (tilt/telescope) inoperative or intermittent
Switch feels loose, sticky, or does not click normally
Steering column moves unexpectedly or only in one direction
Diagnostics show B2351 stored as active or intermittent
Possible other body/comfort functions affected if shared module/power supply

What to check

Read fault memory with a diagnostic scan tool and note freeze-frame/live-data when available
Check for additional related DTCs (power/ground, module communication)
Visually inspect column trim, switch mounting and harness for damage or water ingress
Check relevant fuses and relays for column adjustment circuit
Operate the column adjust switch while monitoring live data or actuation; note response and any intermittent behavior
Wiggle test wiring and connector while observing live data to reproduce fault

Signal parameters

Reference supply typically 5 V or vehicle battery voltage to the switch — verify with wiring diagram
Switch output expected to change between near 0 V (off) and reference voltage (on) OR produce a varying signal (PWM) depending on design
Ground continuity should be near 0 Ω between switch ground pin and chassis ground
Expected current draw for switch circuit is low (
Consult vehicle-specific wiring diagram for exact pin assignments, voltages, and expected resistance values

Diagnostic algorithm

Connect a diagnostic scan tool, record DTC details (status, freeze frame, occurrence count) and clear codes to confirm repeatability.
Perform a visual inspection of the steering column trim, switch assembly and harness for damage, corrosion or water ingress. Repair any physical damage.
Check fuses and relays related to column adjustment power. Replace if blown and retest.
With ignition ON (but engine off unless manufacturer directs otherwise), probe the switch connector: verify reference voltage, ground, and switch output while operating the switch. Compare results to vehicle wiring diagram specs.
If switch output is missing or erratic, disconnect connector and measure switch continuity/resistance while actuating. Replace the switch if internal contacts are open/unstable.
If switch tests OK, perform continuity and resistance checks on wiring between switch and the controlling module; repair any shorts/opens and secure connectors.
If wiring and switch are good but fault persists, check module inputs and communication lines. Reflash or replace the module only after confirming upstream components are good and following manufacturer procedures.
After repairs, clear codes and perform multiple test cycles of column adjustment to confirm the fault does not return. Document repairs and retained codes if intermittent.

Likely causes

Faulty column adjustment switch
Damaged/poor connector or wiring to the switch
Blown fuse or missing reference/ground
Mechanical jam in column adjustment mechanism
Control module fault or software issue

Fault status

⚠️ Status

Control module recorded a fault in the steering column adjustment switch circuit (active or intermittent). May disable column adjustment until repaired.
