Causes

Open or shorted solenoid coil
Poor/ corroded connector or pin contact at the solenoid
Blown fuse or faulty relay feeding the solenoid circuit
Broken/frayed wiring or chafed harness to the steering column
Mechanical binding or obstruction in the telescope mechanism
Water ingress/corrosion in the column area

Symptoms

Telescope (in/out) function inoperative or intermittent
Steering column adjustment may be stuck or not respond
Steering column warning or message on dash (model dependent)
Possible clicking noise or no sound when telescope command given
DTC stored in module and related steering/comfort functions disabled

What to check

Scan vehicle and confirm stored and pending freeze-frame data for B1C34
Attempt to command telescope function with an advanced scan tool (observe behavior)
Visually inspect solenoid connector and wiring for damage, corrosion, or loose pins
Check fuses and relays related to the steering column/telescope circuit
Back-probe connector and measure voltage while commanding the solenoid
Measure solenoid coil resistance with multimeter (connector disconnected)

Signal parameters

Command voltage: typically battery 12 V when solenoid commanded (approx. 11–14 V)
Coil resistance: typical low-voltage solenoid range (approx. 5–40 ohms) — refer to vehicle-specific spec
Current draw: typically 0.2–3 A when energized (varies by design)
Control type: direct battery feed switched/grounded or driven by module (may be PWM on some models)
Activation behavior: audible click or movement when energized if solenoid and mechanism free

Diagnostic algorithm

Retrieve freeze-frame and related codes. Note conditions when code set (ignition state, battery voltage, attempts to adjust).
Visual inspection: inspect solenoid connector, wiring harness through steering column, and nearby grounds for corrosion, damage, or pin push-out.
Check fuses/relays: verify any fuse or relay for steering column adjustment circuits; replace if blown/faulty.
Functional test with scan tool: command the telescope solenoid while an assistant observes connector voltage and listens for actuation.
Electrical test: with connector disconnected measure coil resistance to ground/positive according to wiring design; compare to spec. Back-probe when commanded to confirm proper supply and switching ground.
Continuity test: check continuity and insulation between module connector and solenoid connector; wiggle harness to try to reproduce intermittent faults.
Mechanical check: manually inspect and move the telescope mechanism (with ignition off and battery disconnected where required) to ensure it is not jammed or obstructed.
Repair/replace: repair damaged wiring or connector, replace solenoid if coil out of spec or fails to actuate, replace or service mechanical components if binding. If electrical and mechanical tests are normal, investigate control module and software updates or module replacement as appropriate.
Clear codes and verify repair: erase DTCs, retest telescope operation through multiple cycles, and monitor for reappearance of B1C34 and related codes.

Likely causes

Poor connector contact or corrosion at the solenoid connector
Open/shorted solenoid coil (failed solenoid)
Wiring fault between control module and solenoid (open/short)
Mechanical binding in telescope mechanism preventing movement
Blown fuse or fault in relay supplying the solenoid

Fault status

⚠️ Status

Telescope direction column solenoid fault detected — electrical or functional issue preventing correct operation of the steering column telescope actuator.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-2.5 hours
