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.
Theory Of Operation
Whenever a Fob Integrated Key (FOBIK) is inserted in the Wireless Ignition Node (WIN), the WIN performs a self test and resynchronization routine. During the routine, the WIN interrogates the FOBIK for the secret key information and performs a CAN Bus message handshake with the PCM to start the vehicle. The PCM must reply to the WIN that the secret key information matches to initiate the start sequence or this code will set on the 20th attempt.
