Component Tests and General Diagnostics

The most reliable, efficient, and accurate means to diagnose the remote keyless entry transmitter requires the use of a DRBIII scan tool and the proper Diagnostic Procedures manual. The DRBIII scan tool can provide confirmation that the PCI data bus is functional, and that all of the electronic modules are sending and receiving the proper messages on the PCI data bus.
