Circuit Description

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