2010 Mercury Mariner won't start
I have a 2010 Mercury Mariner Premier V6. When I try to start the car, I hear a chime I haven't heard before. It is two beeps that chime 6 times. It does not happen when we're driving, only when you are starting or shutting off the car. My lights all light up on the display. The Anti-theft light is flashing. I can hear clicks coming from the engine compartment, but nothing happens.
I have already checked the fuses.
When I unplugged the PCM and plugged it back in, I did hear the throttle body engaging, so there is power to the PCM.
The battery is charged. The radio and all my accessories work as they should.
Pleas help. Any suggestions would be appreciated.
