[SOLVED] P1A07 Code: Fixing Battery Energy Control Module Reference Circuit

The P1A07 fault code in automobiles indicates a problem with the Battery Energy Control Module (BECM). The most common symptom is the illumination of the engine light or service engine soon warning light.

The cause of this fault code could be a faulty BECM, an open or shorted BECM harness, or a poor electrical connection in the BECM circuit. It is important to address this issue promptly as it can lead to reduced fuel efficiency and even damage to the battery. The repair process involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector pins.

The repair time for this issue is estimated to be around 1.0 hour. It is crucial to interpret the fault code correctly to ensure the proper repair is performed.
