If your AdvanceTrac is malfunctioning, you should:
1. Check the owner's manual: Your owner's manual should list all fuses and their corresponding circuits. While there isn't a single "AdvanceTrac" fuse, some fuses related to power distribution (like those for the Body Control Module (BCM) or power distribution boxes) could affect its operation if blown. Inspect these carefully.
2. Have it diagnosed by a professional: A mechanic with access to diagnostic equipment can pinpoint the exact cause of the malfunction. This is far more reliable than trying to troubleshoot the system yourself based on fuse checks. They can test the various modules, sensors, and wiring related to the AdvanceTrac system.
Attempting to troubleshoot electrical systems in modern cars without proper knowledge can be dangerous and may lead to further damage. A professional diagnosis is strongly recommended.
