If you're experiencing problems that you suspect might be related to the PCM, you'll need to look at the fuse box diagrams in your owner's manual. Specifically, look for fuses related to the power distribution system, ignition system, and fuel injection system. These all support the PCM's operation. Blown fuses in *these* circuits could indicate a problem indirectly related to the PCM, but a blown fuse is unlikely to be the *direct* cause of a PCM failure.
Instead of focusing on a "computer module fuse," troubleshooting should begin by:
1. Checking the owner's manual: This is crucial. It contains diagrams of the underhood and interior fuse boxes, showing which circuits each fuse protects.
2. Inspecting all relevant fuses: Don't just look for blown fuses; carefully inspect them for corrosion or loose connections.
3. Inspecting relays: Relays often work in conjunction with fuses. Check their condition and connections.
4. Testing the PCM: A proper diagnosis needs a scan tool to check for diagnostic trouble codes (DTCs) stored in the PCM's memory. This will pinpoint the actual problem.
In short, there's no single "computer module fuse". A faulty PCM is usually diagnosed through other means. A mechanic with a scan tool is likely necessary for proper diagnosis and repair.
