The P1A94 fault code indicates that the 14-Volt Power Module is stuck ON.

The Accessory Power Module (APM) controls the energy flow between the 42 V DC and 14 V DC buses. The APM power is bidirectional, with negative current representing 14-42 direction, and positive current representing the 42-14 direction.

When the APM Power Conversion direction is set to Off, the APM will not consume or transfer any power.

The P1A94 fault code may cause issues with the Service Charge or jump start.

What are the possible causes of the P1A94 automobile fault code?

The P1A94 fault code in automobiles is indicated by the engine light turning on.
