For a complete wiring diagram Refer to Section 8W.When Monitored:ContinuouslySet Condition:When the Cluster senses the Horn Switch input for over 30 seconds, this code will set.Possible CausesHORN SWITCHCLOCKSPRING(X3) HORN SWITCH SENSE CIRCUIT SHORTED TO GROUND(X3) HORN SWITCH SENSE CIRCUIT SHORTED TO (Y13) RADIO CONTROL RETURNINSTRUMENT CLUSTER1. TEST FOR INTERMITTENT CONDITIONWith the scan tool, record and erase DTC'sOperate the Horn Switch several times.Cycle the ignition from on to off 3 times.Turn the ignition on.With the scan tool, read DTC's.Does the scan tool display HORN SWITCH STUCK?YesGo To 2NoThe conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)2. HORN SWITCH SHORTED

To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Disconnect the Horn switch connector.With the scan tool, erase DTC'sCycle the ignition from on to off 3 times.Turn the ignition on.With the scan tool, read DTC's.Does the scan tool display HORN SWITCH STUCK?YesGo To 3NoReplace the Horn Switch.Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)3. STEERING WHEEL HARNESS SHORTED

Disconnect the Steering Control Module C5 connector.With the scan tool, erase DTC'sCycle the ignition from on to off 3 times.Turn the ignition on.With the scan tool, read DTC's.Does the scan tool display HORN SWITCH STUCK?YesGo To 4NoRepair/replace the steering wheel jumper harness.Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)4. CLOCKSPRING SHORTED

Disconnect the Steering Control Module C2 connector.With the scan tool, erase DTC'sCycle the ignition from on to off 3 times.Turn the ignition on.With the scan tool, read DTC's.Does the scan tool display HORN SWITCH STUCK?YesGo To 5NoReplace the clockspring.Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)5. (X3) HORN SWITCH SENSE SHORTED TO GROUND

Turn the ignition off.Disconnect the Cluster C2 and C3 connector.Measure the resistance between (X3) Horn Switch Sense and the (X13) Radio Control Return circuit.Is the resistance below 1000.0 ohms?YesRepair the (X3) Horn Switch Sense circuit for a short to (X13) Radio Control Return circuit.Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)NoGo To 66. (X3) HORN SWITCH SENSE SHORTED TO GROUND

Measure the (X3) Horn Switch Sense circuit to ground.Is the resistance below 1000.0 ohms?YesRepair the Horn Switch Sense circuit for a short to ground.Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)NoReplace the Cluster.Perform BODY VERIFICATION TEST - VER 1.
