U1109 on Jeep
Lost Communication With LIN Steering Wheel Controls
U1109 on Jeep vehicles indicates lost communication with lin steering wheel controls. Au7o has documented this code across 1 Jeep model — most commonly on Wrangler. A Stellantis/FCA network code (Chrysler, Dodge, Jeep, RAM). The instrument cluster stopped receiving messages from the steering wheel control switches over the LIN bus — the low-speed single-wire network linking simple switch modules to the cluster. The vehicle drives normally, but the steering wheel buttons (radio volume, cruise control, phone, menu) stop responding, and on some models the horn is affected as well. It is an electrical/communication fault, not a mechanical one. Typical repair costs on Jeep range from $200 to $600, depending on the specific model and root cause.
Common Causes of U1109
- •Failed steering wheel switch module (left or right switch pod)
- •Damaged clockspring in the steering column — the ribbon that carries these circuits through the rotating wheel
- •Open, shorted, or chafed LIN bus wiring between the steering wheel and the cluster
- •Poor or corroded connector contact at the switch pod or clockspring
- •Failed instrument cluster (the LIN master for this circuit)
- •Low system voltage or a weak battery causing intermittent LIN dropouts

- Steering Column Clockspring Failure — Airbag Warning Light, Dead Horn / Cruise / Wheel Controls2007-2017
The clockspring (a coiled ribbon-cable assembly behind the steering wheel that maintains electrical continuity to the driver airbag, horn, cruise control, and steering-wheel radio controls while the wheel turns) is a chronic Wrangler failure point, aggravated by off-road dust intrusion and vibration. Dust contamination of the flexible conductor's grease causes it to bend abnormally and the circuits to wear open — most critically the driver-airbag squib circuit, which may not deploy in a crash. NHTSA recall 16V-288 (Safety Recall S40) covered 2011-2016 RIGHT-hand-drive Wranglers; a companion recall covered earlier RHD units, and NHTSA investigated 2007-2012 left-hand-drive Wranglers. For 2011-2016 LEFT-hand-drive Wranglers, FCA did NOT recall but issued Customer Satisfaction Notification X68 (bulletin D-17-01) extending the clockspring warranty to 15 years/unlimited miles due to the failure rate. The airbag circuit can fail while horn/cruise still work, or vice versa.
