Compass: Testing and Inspection

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.

For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector
repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness
connectors, splices and grounds.

Refer to the appropriate diagnostic information.
