Module - Police/Taxi Interface

Any diagnosis of the Police/Taxi Interface Module (PTIM) should begin with the use of a scan tool and the proper Diagnostic Procedures Information. The scan tool can provide confirmation that the Controller Area Network (CAN) Data Bus is functional and that all of the electronic modules are sending and receiving the proper messages on the CAN Data Bus.
