This code means there's a problem with the part of the car that disconnects the high voltage battery for safety. It's like a switch that isn't working right.
The P0B36 code is triggered when the vehicle's control module detects a high voltage condition in the service disconnect circuit.
The high voltage service disconnect is a safety feature in hybrid and electric vehicles that allows for the safe disconnection of the high voltage battery from the vehicle's electrical system. A 'Circuit High' condition indicates that the voltage reading is higher than expected, which could be due to a faulty sensor, wiring issue, or malfunctioning disconnect switch.
• Check Engine Light illuminated
• Vehicle may not start
• Reduced performance or power
• Faulty high voltage service disconnect switch
• Wiring issues or damaged connectors
• Faulty control module
High Voltage: Electrical systems that operate at voltages higher than standard vehicle systems.
Service Disconnect: A switch that safely disconnects the high voltage battery from the vehicle.
• Use an OBD-II scanner to confirm the P0B36 code.
• Inspect the high voltage service disconnect switch and related wiring for damage.
• Test the voltage levels in the circuit to ensure they are within specifications.
• Replace the high voltage service disconnect switch if faulty.
• Repair or replace damaged wiring or connectors.
• Update or replace the control module if necessary.
• OBD-II scanner
• Multimeter
• Wiring repair tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks on high voltage components
• Avoid exposure of electrical components to moisture
• Ensure proper handling during repairs
Electrical Circuit Issue
• Do not attempt to repair high voltage systems without proper training.
• Consult a professional technician for diagnosis and repair.
Repairs may be covered under the vehicle's powertrain or emissions warranty.
This code has become more common with the increase in hybrid and electric vehicles, highlighting the importance of maintaining high voltage systems.
High – This issue can affect vehicle safety and performance.
Handling high voltage systems can be dangerous. Always follow safety guidelines and consult a professional.
• Vehicle in 'ON' position
• Battery fully charged
The high voltage service disconnect is typically located near the vehicle's battery pack, often accessible through a panel or compartment.
Q: Can I drive with a P0B36 code?
A: It's not recommended to drive with this code as it can affect vehicle safety and performance.
Q: Is a P0B36 code serious?
A: Yes, it indicates a potential safety issue with the high voltage system.
