Component Tests and General Diagnostics

POWER LOCKS
The most reliable, efficient, and accurate means to diagnose the power lock system requires the use of a scan tool. The scan tool can provide confirmation that the PCI data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the PCI data bus, and that the power lock motors are being sent the proper hard wired outputs by the relays for them to perform their power lock system functions.
