P1A31: Decoding The Elusive Hybrid Battery System Fault
The P1A31 code is related to the Hybrid Battery 3 Circuit High Voltage. Battery voltage sensors are used to monitor the voltage of the batteries in the Energy Storage Box (ESB).
The ESCM monitors the voltage drop across the battery voltage sensors and uses the inputs for hybrid calculations.
When the battery voltage is high, the resistances of the sensors are high and the voltage signals are high. When the battery voltage is low, the resistances of the sensors are low and the voltage signals are low.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P1A31 fault code. This code is usually caused by a faulty Energy Storage Box (ESB) battery, a faulty Battery Energy Control Module (BECM), an open or shorted BECM harness, or a poor electrical connection in the BECM circuit. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector pins.
If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P1A31 fault code, there are a few things you can do to fix it. First, check for a faulty Energy Storage Box (ESB) Battery or Battery Energy Control Module (BECM). If those are not the issue, visually inspect the related wiring harness and connectors.
