DIAGNOSTIC INFORMATION AND PROCEDURES
SYMPTOMS - STEERING WHEEL AND COLUMN
Review the system description and operation in order to familiarize yourself with the system functions. Refer to
Steering Wheel and Column Description and Operation.
Visual/Physical Inspection



Inspect for aftermarket devices which could affect the operation of the steering wheel and column.
Inspect the easily accessible or visible system components for obvious damage or conditions which could
cause the symptom.

Symptoms List

Refer to a symptom diagnostic procedure from the following list in order to diagnose the symptom:







Steering Column Tilt Function Inoperative
Ignition Key Cannot Be Removed from the Ignition Lock Cylinder
Ignition Key Cannot Turn or Sticks in Any Position
Noise in Steering Column
High Shift Effort
Looseness in Steering Column

HEATED STEERING WHEEL INDICATOR MALFUNCTION
Diagnostic Aids


If the cruise control indicator works but the heated steering wheel indicator does not, then the problem
does not lie with the BCM or with the LED signal circuit.
