The estimated repair time for this fault code is 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p0ade fault code.

The P0ADE fault code refers to the Hybrid Battery Negative Contactor Control Circuit RangePerformance. This code is related to the operation of the System Main Relays (SMRs) in the high-voltage power supply circuit.

The SMRs are responsible for connecting and disconnecting the high-voltage power supply circuit as requested by the HV control ECU.

There are a total of 3 relays, with 1 for the negative side and 2 for the positive side. During the connection process, SMR1 and SMR3 initially turn ON, followed by SMR2. This sequence helps protect the circuit from high-voltage surge current by allowing the limit current to flow through a resistor.

When disconnecting, SMR2 and SMR3 turn OFF in that order.

The HV control ECU verifies that the relays have turned OFF properly to ensure proper operation.

The P0ADE fault code indicates that there may be a malfunction in the Hybrid Battery Negative Contactor Control Circuit.

It is important to address this issue promptly to maintain the reliable operation of the high-voltage power supply circuit.

What are the possible causes of the automobile fault code P0ADE?

If you see the engine light or service engine soon warning light on, it could be due to the fault code P0ADE. This code is often caused by a faulty system main relay, an open or shorted relay harness, a poor electrical connection in the relay circuit, or a faulty HV control ECU. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the P0ADE fault code?

To fix the P0ADE fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify any issues with the System Main Relay or its circuit. Don’t forget to also check for poor electrical connections. By addressing these possible causes, you can resolve the issue and turn off the Engine Light or Service Engine Soon Warning Light.

What should I look for when checking for damaged components and connector’s pins to resolve the P0ADE fault code?

When resolving the P0ADE fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. By doing so, you can identify any issues that may be causing the fault code and take the necessary steps to fix them.
