The P3241 code is related to the hybridEV battery interface control module.

It performs a cell overvoltage sense circuit test during every power up cycle.

The module informs the powertrain control module 2 about the diagnostics on the overvoltage sense circuit. The module then commands each of its internal sense circuits to run the check on its output. If a cell group voltage of greater than 4.5 V is detected, the Diagnostic Trouble Code (DTC) will be set.

What are the possible causes of the P3241 automobile fault code?

If you’re experiencing the P3241 fault code, your engine light may be on. This could be due to a faulty Hybrid/EV Battery Interface Control Module 2, an open or shorted harness, or poor electrical connection in the circuit. To fix the issue, inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the wiring harness and connectors related to the Hybrid/EV Battery Interface Control Module 2?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Hybrid/EV Battery Interface Control Module 2, you can visually inspect the related wiring harness and connectors to fix the issue.
