Causes

Failed/shorted/open steering tilt solenoid (coil or actuator)
Broken, chafed or corroded wiring or terminals at the solenoid connector
Poor ground or lost 12 V supply (blown fuse, faulty relay, poor contact)
Connector corrosion, water ingress or loose terminal
Mechanical binding or obstruction in the tilt mechanism
Faulty Body/Steering control module or software anomaly

Symptoms

Steering tilt does not move when command is given
Steering tilt moves intermittently or slowly
Clicking or humming noise from steering column area
One or more related DTCs stored and possible steering/system warning
Tilt position not stored or cannot be adjusted

What to check

Read and record all stored DTCs and freeze frame data; note any related codes
Visually inspect steering column trim, solenoid connector, wiring harness and grounding points for damage or corrosion
Check fuses and relays for the tilt/steering circuit
Measure battery voltage at the vehicle (should be ~11–14 V with key on and engine off)
Backprobe solenoid connector to verify presence of 12 V supply and ground while commanding tilt
Measure solenoid coil resistance at the connector with harness disconnected

Signal parameters

Battery supply voltage to solenoid: ≈ 11–14 V (key on/engine running as applicable)
Solenoid coil resistance: typically low ohms; commonly in the range 1–50 Ω (consult vehicle service data for exact value)
Control signal: either switched 12 V or PWM from control module; duty cycle varies when commanding movement
Expected current draw: can be up to several amps during actuation (depends on design)
PWM frequency (if used): commonly tens to a few hundred Hz (refer to manufacturer data)

Diagnostic algorithm

Retrieve DTC B1C32 and any related codes; record freeze-frame and attempt to reproduce the fault by commanding tilt.
Visually inspect connector and wiring for corrosion, pin damage, chafing or moisture. Repair any obvious damage.
With ignition off, disconnect solenoid harness and measure coil resistance across the solenoid terminals; compare to service spec. Replace solenoid if open/shorted or out of spec.
Reconnect harness. With a DVOM or scope, backprobe the connector and verify battery voltage is present at the supply pin with key on. Check ground continuity to chassis ground.
With diagnostic tool, command the tilt solenoid while monitoring supply voltage and control output. Observe for PWM or switched voltage and check for voltage drop or excessive current draw.
If power/ground are good and module commands are present but solenoid does not operate, remove and bench-test or replace the solenoid. Inspect the mechanical tilt mechanism for binding and clear any obstruction.
If no command from control module or inconsistent control signal, verify wiring continuity between module and solenoid. Repair open/short/poor connections as needed.
After repairs, clear codes, re-test multiple cycles and road test. If fault returns and wiring/solenoid are confirmed good, consider control module diagnosis or reprogramming per manufacturer procedures.

Likely causes

Damaged or corroded connector at the tilt solenoid
Open or high-resistance solenoid coil
Blown fuse or poor power/ground to the solenoid
Mechanical jam preventing movement
Intermittent wiring fault between module and solenoid
