My 2007 Dodge Magnum SRT8 has multiple failures of electrical equipment and 64 ODB codes. It appears that the d55 circuit has an issue.
Is this circuit fused in any way other than the number three circuit breaker?-
The D55 circuit in your 2007 Dodge Magnum SRT8 is part of the CAN system, which handles data signals between control modules rather than powering solenoids or motors. It isn't fused beyond the #3 circuit breaker, but issues like multiple codes and equipment failures often stem from CAN communication faults, such as wiring, connectors, or ground issues.
Possible Solution:
Inspect the CAN wiring harness and connections for damage or corrosion, especially at common ground points and near the Power Distribution Center (PDC). Ensure the #3 circuit breaker is functioning properly, and test continuity and resistance in the D55 circuit to identify any shorts or open circuits.
