Error Code P0512: What It Means & What To Do?

<<See All OBD Codes

OBD Code P0512? Alarmed? Don’t worry, Parts Avatar is here at your service! The code P0512 is a generic trouble diagnostic code signalling a malfunction in the starter request. The starter relay gets a signal from the engine control module (PCM) and further informs the starter to crank the engine. If the PCM notices an incorrect signal to the starter relay or the starter, it sets the code P0512.

First step: starting a car which is no sweat at all, just put the key in the ignition and with a turn you’re ready! But the procedures that follow may be much harder than apparent. The mechanical keys are bunched along with the resistors and radio transponders with unique codes. The last part being true with today’s push-button ignition systems. Only in these types of vehicles the code P0512 triggers. Also, the E-Engine immobilizer system in the vehicle should be programmed in a way to detect the transponder. Most importantly, it should be noted that the transponder sends off a signal that is identified by the immobilizer with the help of a tiny antenna. Once the signals are identified and observed, the driver only needs to step on the brake pedal and press the start button in order to bring the vehicle back to life.

What causes this problem with Starter Request Circuit?

• A poor electrical connection obstructing the Immobilizer’ ability to detect the accurate signal
• Defective or disconnected Immobilizer antenna
• An open or short circuit holding up the ability of the immobilizer from recognizing the correct signal
• A possible fault in the transponder inside the owner’s fob.
• An insufficient voltage received due to a weak battery (the engine demands higher energy while starting up)

1. Powertrain Control Module - Abbreviated PCM; this is an integral control unit. So, a defective one should be changed immediately. Tune into Parts Avatar for excellent quality PCMs at the process you have always been looking for.
2. Scanner - Having problems with the scanner? Don’t you worry, Parts Avatar has it all. A faulty scanner could end up being the root cause behind the error code P0512.
3. Connectors - Weary and damage connectors can often be problematic. So, to add some spark to your ride you definitely need the perfect quality connectors offered at Parts Avatar. Isn’t that just the perfect deal?

Curious to know the symptoms of the Error Code P0512? If yes, then you have checked into the right place. We have listed here a few common symptoms that should e taken care of.

Common Symptoms

• The engine may not start
• Longer starter engagement (the start may require multiple key cycles)
• A possible failure in the PCM power circuit or ignition system circuit codes may accompany this code
• Also, one should be cautious as there are times with no symptoms at all

Here’s how you can correct the Starter Request Circuit error with Parts Avatar:

• The disconnected, broken, burnt or shortened connectors, wirings or parts should be replaced or repaired
• The Immobilizer Antenna should be mended or changed
• Restoring or replacing the fob
• Lack of sufficient voltage should be addressed and taken care of

There is no need to be stressed if your OBD Code is still popping up as we are here at your service.

To start with the diagnosis, the mechanic should start by using an OBD-II scanner to confirm the P0512 code has been stored and see if other codes have been stored as well (like P0513 and P0633, both of which deal with the issues of the Immobilizer). Next, the mechanic should move on to investigate the fob for a broken or an unsound antenna ring or damage that maybe keeping it from working. If those parts seem fine, they will next examine all the wirings and electrical connectors connected to the Immobilizer to make sure they are all working in order.

Common Mistakes When Diagnosing the P0512 Code

Tensed about a misdiagnose? Well, here listed are a few common mistakes that should be paid attention to.

When the vehicle fails to answer to the owner’s fob, most mechanics look at the issue early on. Sadly, if there is an audible cranking, most of the times it is assumed that the issue deals with the fuel and ignition system. So, they start looking at the ignition coils, fuel injectors and fuel pumps for the hints of the malfunction.
