The P0A96: Hybrid Battery Pack Cooling Fan 2 Control Circuit/Open fault code indicates that the control circuit for cooling fan 2 is either open or malfunctioning. This may be due to an open circuit, a faulty cooling fan, or wiring problems.
P0A96 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0A96: Hybrid Battery Pack Cooling Fan 2 Control Circuit/Open |
| Is it serious? | Yes, as a non-functional cooling fan can lead to battery overheating, reducing the battery’s lifespan or performance. |
| Possible causes | – Open circuit in cooling fan 2 control – Faulty cooling fan 2 – Wiring issue |
| How to diagnose? | – Inspect cooling fan 2 control circuit – Test cooling fan 2 functionality – Check wiring for open circuits |
P0A96 Meaning
The P0A96: Hybrid Battery Pack Cooling Fan 2 Control Circuit/Open code indicates that the control circuit responsible for operating cooling fan 2 is open, meaning that electrical signals are not reaching the fan. This may prevent the fan from working, leading to inadequate cooling for the hybrid battery pack. The issue could be a fault in the fan, the control circuit, or wiring between components.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional fault codes related to the cooling system or electrical circuits that could provide more details. | OBD-II Scanner |
| Inspect Cooling Fan 2 Control Circuit | Visually inspect the control circuit for cooling fan 2. Check for signs of damage, wear, or disconnection in the wiring and connectors that may be causing an open circuit. | Flashlight, Multimeter |
| Test Cooling Fan 2 Functionality | Use a diagnostic tool to test cooling fan 2’s operation. Ensure that the fan turns on when commanded by the control system and that it runs at the correct speed. | Diagnostic Tool, Multimeter |
| Check Wiring for Open Circuits | Use a multimeter to test the wiring connected to cooling fan 2 for continuity. An open circuit will show no continuity and may indicate a break in the wiring or a faulty connector. | Multimeter |
| Test Fan Relay and Fuse | Inspect the relay and fuses associated with cooling fan 2. A blown fuse or faulty relay could result in an open circuit. Replace them as necessary. | Fuse Tester, Relay Tester |
| Replace Cooling Fan if Faulty | If the cooling fan is not functioning and shows signs of failure, replace it with a new or OEM-compatible fan to restore cooling performance. | Replacement Cooling Fan |
| Clear the Code and Test Drive | After repairs, clear the fault code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0A96 code does not return. | OBD-II Scanner |
