Switches Function Intermittently Or Not At All
This bulletin involves inspecting and replacing the right side steering wheel mounted speed
control switch if necessary.
2011 (JK) Wrangler
2011 (MK) Compass
NOTE: This bulletin applies to vehicles built prior to June 1, 2011 (MDH 0601XX).
Both of the following symptom/Conditions must be exhibited:
1. The steering wheel mounted audio and/or EVIC switches may function intermittently
or not at all. It may be noticed that the switch works properly after using the horn,
unplugging and reconnecting the steering wheel switches or a battery disconnect.
2. The speed control switches function properly.
NOTE: The Audio/EVIC switches are hard wired (MUX) to the Speed control switch
and then the Speed control switch communicates over a LIN bus to the
cluster. This concern was caused by the Speed control switch not properly
communicating with the Cabin Compartment Node (CCN). This concern only
affected the Audio/EVIC switch inputs not the Speed control inputs.
NOTE: DTC U1109 - Lost Communication with LIN Steering Wheel Controls may, or
may not, be stored in the (CCN).
