Causes

Corroded or loose connector at the switchpack
Broken or chafed wiring in the steering column harness or multi-plug
Faulty switchpack module (steering-column switch unit)
Damaged or worn clock spring (spiral cable) causing intermittent contact
Low or intermittent supply/ground voltage to the switchpack
CAN/CAN-FD bus wiring fault, short or high resistance connection

Symptoms

Steering wheel switches non-functional or intermittent (audio, cruise, phone, voice)
Warning or message on dash related to steering controls or communication fault
Loss of associated systems that rely on switchpack inputs (cruise control, audio controls)
DTC U2013 stored in one or more control modules and may reappear after code clear
Intermittent faults that occur when steering is turned or vehicle crosses bumps

What to check

Read all stored DTCs and freeze-frame data from all modules using a capable diagnostic tool
Check battery voltage and charging system; record voltage while operating switches
Inspect steering column area for damaged harness, chafed wires, or connector corrosion
Visually inspect and reseat switchpack connector(s) and any intermediate junctions
Perform a wiggle test on steering column wiring while monitoring live data for loss of messages
Check for other network U-codes that indicate a wider CAN bus problem

Signal parameters

Expected CAN bus idle voltages: CAN_H ≈ 2.5 V, CAN_L ≈ 2.5 V (approx. half Vbatt with both terminated)
Dominant CAN state: CAN_H ~3.5 V, CAN_L ~1.5 V (during transmission)
Supply voltage to switchpack: nominal battery voltage (approx. 12–14 V)
Ground continuity from switchpack housing to chassis ground: near 0 ohms
Message presence: switchpack-related CAN message IDs and data bytes present/absent in module datastream (compare to known-good if available)
Resistance/continuity of clock spring contacts when rotating steering wheel (if accessible)

Diagnostic algorithm

Connect a diagnostic scan tool and record U2013 with all related codes and freeze-frame data. Note occurrence conditions and ignition cycle behaviour.
Verify battery and charging system voltage; charge or replace battery if low. Repeat the test with stable voltage.
With ignition on, monitor live CAN messages and switchpack-related parameters. Attempt to operate steering wheel switches and watch for message loss or errors.
Visually inspect the switchpack connector(s) for corrosion, bent pins, or water ingress. Repair or clean as required, then retest.
Perform wiggle tests on the steering column harness and connectors while monitoring live data to reproduce the fault. Pay attention while turning the steering wheel through full travel.
If intermittent communication coincides with steering movement, inspect and test the clock spring/spiral cable. Replace clock spring if contacts are open or intermittent.
Measure CAN_H and CAN_L voltages and check termination resistances (approx. 60 ohms across CAN_H and CAN_L when network powered). Repair any short/open/poor terminations.
Check power and ground circuits to the switchpack for correct voltage and solid ground. Repair wiring as needed.
If wiring and connectors are good but fault persists, consider switchpack module replacement or reflashing to correct software mismatch. Follow manufacturer procedures for module coding/programming.
After repairs, clear codes and road-test to confirm fault does not return. If intermittent and persists, consult manufacturer technical bulletins and wiring diagrams for module-specific tests.

Likely causes

Connector corrosion or poor pin contact in steering column harness
Wiring damage due to steering movement (pinched/abraded wires)
Failed clock spring causing intermittent signals to the switchpack
Defective switchpack module internal electronics
System voltage irregularities (low battery or poor ground)

Fault status

⚠️ Status

Module reports invalid or missing communication from the switchpack (steering-column switch unit). Event logged as U2013 — intermittent or permanent loss of expected data from the switchpack.

🟡 Repair difficulty: Medium
