GM KEY CODES CODE
The P0513 code can actually be quite serious. In most cases, the problem has to do with the key. They may actually replace the ignition cylinder and find out that the code remains and that they have another problem. Instead, they may look at the ignition cylinder since the vehicle has trouble starting or will not start at all. Sometimes, a mechanic may overlook the fact that the error is actually caused by a problem with the immobilizer key. Common mistakes when diagnosing the P0513 code Mechanics should start at the simplest potential issues first and then work their way up. They can then start looking into the actual issues that would cause the code to appear, such as the faulty immobilizer key antenna or faulty immobilizer key. If the code does return, then they know they’re dealing with a real problem rather than a false code. After resetting the code, they will want to drive the vehicle to see if the code returns. They will check for the stored trouble codes and will then reset the code. How does a mechanic diagnose the P0513 code?ĭiagnosis of the P0513 code starts with the mechanic connecting his or her scanning device to the vehicle’s onboard computer. In addition, the engine may be more difficult to start and in severe cases it may not start at all. Those who have the P0513 trouble code stored on their vehicle will often find that their Check Engine Light is lit, as well as their security Light. Poor electrical connection for immobilizer circuit components.The following are some of the most common causes of the P0513 code. If the key identity is not the same as the programmed identity, then a trouble code will be stored and the malfunction indicator light could come on. These include the powertrain interface module, or PIM, the body control module, or BCM, and the powertrain control module, or PCM. There are three different elements that work together as a means to authenticate the identity of the vehicle immobilizer key. When the P0513 trouble code appears, it indicates that the powertrain control module has found an issue with the immobilizer key ID.
