Circuit Description

When a program request has been selected with Driver Information Center (DIC) switches and is recognized by Central Control Module (CCM), the CCM's program request output grounds the PKE program request input for about 100 milliseconds before allowing the program request input to return to a 5-volt level. This signal is read by the PKE program request input which supplies the 5-volt pull-up for the circuit. See TRANSMITTER PROGRAMMING  for programming procedures and information.
