Guide To P0C87 OBD Error Code Solutions

<<See All OBD Codes

The P0C87 error code usually describes the wiring issue and is generally defined as hybrid battery temperature sensor “G/H” correlation. Generally, the hybrid battery pack will use multiple sensors so that it can monitor the temperature of each battery cell. If an unlikely temperature is reported by at least one of the battery temperature sensors, then the P0C87 error code will be set in the vehicle. The failure in multiple sensors will disable the high voltage system.

The battery temperature sensor is available in 3 places of the HV battery. Depending on the thermistor’s resistance, that is inbuilt in each and every battery temperature sensor, the resistance will change according to the changes in the HV battery temperature. Lower the battery temperature means, higher the resistance of the thermistor. Similarly, lower the resistance also means higher the temperature. The temperature of the HV battery is found by the battery smart unit with the help of battery temperature sensor which finally sends the identified value to the power management control ECU. Depending on this finding, the blower fan is then controlled by the power management control ECU where the blower fan will start functioning once the temperature of the HV battery rises above a particular level.

Well, if you are looking to know about the common symptoms related to this error code P0C87, we are have worked out a small list to help you discover this error code with your vehicle.

Common Symptoms

• You will notice that the engine light is turned on.

Learn the ways with which you can correct this trouble code P0C86:

• The malfunctioning battery smart unit must be changed.
• The hybrid battery thermistor’s harness and the circuit which is defective needs a quick replacement.
• Changing the broken hybrid battery thermistor.

We are sure that now all your issues would be resolved.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• The P0B15 diagnostic trouble code is not very difficult to diagnose or carry out
• If this error code appears in your vehicle it is always best to have a qualified technician or mechanic to look at this error code, where he will use a scanner to find out the problem.
• With the help of a scanner, the mechanic will recover every of the stored codes and freeze frame data by connecting it to the diagnostic port of the vehicle.
• Initially, the mechanic will begin by checking the hybrid battery thermistor and hybrid battery thermistor harness as it can cause issues in your vehicle. Also, they can be one of the reason if the error code is stored in the vehicle.
• After this, the mechanic will look after the components like high voltage battery assembly and high voltage battery control module for any damages and defects. Necessary repairs will be carried out if they are defective.
• Finally, the battery smart unit will be inspected for any possible damages. Once every diagnosis and repairs are properly done, it is very important to retest the code and test drive the vehicle to see if the error codes, still appear and if the engine light keeps blinking.

Common Mistakes When Diagnosing The P0C87 Code

The common mistakes that are made while diagnosing the P0C87 error is that you might find the high voltage battery assembly, the electrical wires, and the high voltage battery interface control module to be defective.
