Functions that might be considered "timing" are handled by different modules, including but not limited to:
* Powertrain Control Module (PCM): This is the main computer and handles most engine timing, including fuel injection, ignition timing, and various other engine control functions. It's usually located under the hood, often near the firewall.
* Body Control Module (BCM): This module controls many electrical functions, and some of those have timing aspects (like lighting sequences, door lock timing, etc.). Its location varies depending on the specific trim level but is often under the dash.
* Other Modules: Depending on options (like sunroof, power seats, etc.), other control modules might have their own timing functions.
If you are experiencing a timing-related problem (e.g., intermittent electrical issues, malfunctioning accessories), you'll need to use a scan tool to diagnose the problem and determine which module is at fault. A mechanic or experienced auto electrician will have the tools and knowledge to perform this diagnosis. Simply trying to find a "central timer module" will likely be fruitless.
