Police / Special Vehicle Options: Description and Operation
DESCRIPTION
The Police/Taxi Interface Module (PTIM) (1) serves as an interface between the "aftermarket module" and various control modules of the vehicle. It is
located in the instrument panel center stack (2) where the ash receiver is normally located on non-fleet equipped vehicles. Depending on the request from
the "aftermarket module", the PTIM retrieves information from the Front Control Module (FCM), Wireless Ignition Node (WIN) Occupant restraint
controller (ORC), Cabin Compartment Node (CCN), and Steering Column Module (SCM) via the Controller Area Network (CAN)-B data bus and
makes them available for specific applications that the "aftermarket module" may apply. This microprocessor based module shall be in "sleep mode" or
"wake-up mode" based on the status of the CAN BUS. The PTIM is operational when battery power is supplied independent of the ignition switch
power.
