Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Key Capture Solenoid
The key capture solenoid allows the ignition control knob to be rotated through its various positions: OFF, ACCY, CRANK and RUN. The key capture solenoid is controlled by the RCDLR. Ground is applied to key capture solenoid through the park switch. If the vehicle is not in park, the solenoid will not be activated and the ignition control knob cannot be turned to the off position.
When the ignition control knob is pushed in or the brake pedal is pressed, the RCDLR looks for a valid transmitter on the interior of the vehicle. If a valid transmitter is detected, the RCDLR applies voltage to the key capture solenoid control circuit, which then allows the ignition control knob to be turned to the RUN position.
