Circuit Description

Cruise Control (CC) brake switch is a normally closed switch. When CC brake switch is closed, PCM senses ignition voltage on CC brake switch signal circuit. DTC will set if PCM senses CC brake switch signal circuit voltage when CC brake switch should be open.

DTC will set when the following conditions are present:

• Engine speed greater than 1000 RPM.
• Engine operating more than 2 seconds.
• Wheel speed greater than 20 MPH to enable diagnostic. Diagnostic will be disabled at less than 5 MPH.
• PCM detects switch is not toggling as compared with other brake switch inputs.
• Conditions are met for 10 accel/decel cycles.
