The fault code P1A56 indicates an issue with the hybrid battery system.

The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour. Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the availability of replacement parts.

It is important to address this issue promptly to avoid further damage to the vehicle and ensure its safe operation.

The P1A56 code is related to the hybridEV system voltage.

The power inverter module contains DC high voltage capacitors and a resistor circuit.

The hybridEV powertrain control module 1 monitors the high voltage level before and after the resistor circuit is connected.

If the voltage level remains high for too long, the P1A56 code is set and the motor control modules are commanded to discharge the capacitors.

What are the possible causes of the P1A56 automobile fault code?

If your engine light is on and you’re seeing the P1A56 fault code, it could be due to a faulty Power Inverter Module, an open or shorted harness, or poor electrical connection in the circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P1A56 fault code?

If you’re experiencing the P1A56 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, there are a few possible causes. One of them is a faulty Power Inverter Module, an open or shorted harness, or a poor electrical connection in the Power Inverter Module circuit. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

What are the consequences of ignoring the P1A56 fault code and not fixing it in a timely manner?
