Causes

  • Open or short in speed control switch wiring
  • Corroded or loose connector at the steering column or BCM
  • Faulty speed control (cruise) switch assembly on the steering wheel
  • Damaged or worn clock spring (spiral cable) in steering column
  • Blown fuse or poor power/ground to module
  • Faulty BCM/PCM or internal module fault

Symptoms

  • Cruise control inoperative or will not engage
  • Cruise control warning/message on dash
  • Steering wheel speed control buttons unresponsive or intermittent
  • Possible stored or active DTC P0568
  • Occasional erratic behavior of other steering wheel controls (audio, phone)

What to check

  • Read freeze-frame and live data with an OBD-II scanner; confirm P0568 is present and note conditions (ignition state, speed, RPM).
  • Inspect fuses related to the cruise/BCM and steering column circuits.
  • Visually inspect steering column wiring, connectors and clock spring area for damage or corrosion.
  • Back-probe the speed control switch connector and measure reference voltage, switch outputs and continuity while operating switches.
  • Wiggle test wiring/clock spring while watching live data to reproduce the fault.
  • Check for related DTCs in BCM or other modules that share the same circuit.

Signal parameters

  • Reference supply typically 5 V (module dependent) to the steering wheel switch assembly
  • Switch output: varies between ~0 V (ground) and reference voltage depending on design/position — expected stable, distinct voltages for each switch press
  • Open circuit: infinite resistance; Closed switch: near 0 Ω continuity between switch terminal and return
  • No more than a few ohms resistance across a closed mechanical switch contact (exact values vary by design)
  • No rapid voltage fluctuation or intermittent losses when pressing/releasing switches

Diagnostic algorithm

  1. Connect a diagnostic scanner. Verify P0568 is stored and note any related codes or freeze-frame data. Clear code and attempt to re-create the fault.
  2. Check fuses and power/ground at the BCM and any steering-column control modules. Repair any blown fuses or poor grounds.
  3. With ignition ON, back-probe the speed control switch connector (or steering wheel module plug). Verify reference voltage (typically ~5V) is present and measure output when buttons are pressed. Compare to expected stable voltages.
  4. Perform continuity/resistance checks between the switch terminals and the BCM/steering module connector. Inspect for opens or high resistance.
  5. Inspect steering column wiring harness and connectors for chafing, pin damage, corrosion, or water ingress. Pay special attention to the clock spring/spiral cable area. Perform wiggle test while watching live data to detect intermittent faults.
  6. If wiring and connectors are OK but switch outputs are incorrect, remove and bench-test the cruise control switch assembly or steering wheel module per vehicle procedure. Replace if faulty.
  7. If switch and wiring test good, test or reflash BCM/steering module software as per manufacturer bulletins. Replace module only after confirming wiring and input devices are good.
  8. After repairs, clear codes and verify proper operation of cruise control and that the code does not return in normal driving conditions.

Likely causes

  • Broken or chafed wire in harness between steering wheel and body (clock spring area)
  • Intermittent connector contact at steering column connector
  • Failed cruise switch due to moisture or wear
  • Faulty clock spring causing intermittent continuity
  • Loss of reference or ground at the controlling module

Fault status

⚠️ Status
Malfunction in speed control switch circuit detected. Cruise control may be inoperative or intermittent; steering wheel switch signals out of expected range.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5 - 2.5 hours
