The P1A29 fault code in automobiles indicates a problem with the Energy Storage Box (ESB) Battery or 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 issue could be a faulty ESB battery, BECM, or a poor electrical connection in the BECM circuit. The repair importance is high as it affects the performance of the vehicle. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors for any damage or corrosion.
The fault code can be interpreted using an OBD-II scanner.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 10.0 (Out of 10) |

P1A29: Your Car’s Battery Is In Trouble
The P1A29 code is related to the Hybrid Battery 2 Circuit Low 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 low, the resistances of the sensors are low and the voltage signals are low, triggering the P1A29 code.
