First of all, I must remark that the Porsche is a far better driving vehicle in terms of both the car itself and the way it handles.
In the two months that I’ve had the car, I’ve already experienced two distinct PCM buggy problems.
Last month, when I started the car, it wouldn’t recognize that my seat belt was fastened. Instead, it beeped for the occupant to fasten their seatbelt. I tried buckling and unbuckling my seatbelt several times, parking the car, turning the ignition on and off, and fastening all the seatbelts throughout the vehicle, but this did not stop the beeping. Eventually, the error persisted.
When I wrote my sales representative to ask how to reset the PCM, he replied that the only way to do so was to turn the car off, lock it, and remove the key; after 45 minutes, it will reset on its own. It is evident that waiting 45 minutes is not the best situation. The car operated as intended the following time I used it.
Today, my PCM screen did not function at all; all I could see was a blue circle rotating throughout the 45 minutes I spent traveling. I tried turning the car on and off, but it was ineffective. I’ve included a photo of it.
It makes sense that every car has software bugs, but there needs to be a mechanism to reset the computer system. On the Tesla, all I had to do to restart it was press and hold two buttons on the steering wheel for six seconds. Does the Taycan offer an alternative to locking the doors and shutting off the engine for 45 minutes to restart the computer system?
If anyone else has this and needs to use the screen momentarily, I’ve found a short cure that lasts for about 30 seconds.
Start the park assist from the lower screen, then press the settings button from there, followed by the home button. Don’t X it out because that would return you to the spinning circle. It will function for roughly 30 seconds before returning to the spinning circle.
How do I locate my Porsche PCM?
Versions of the firmware and navigation vary amongst Porsche PCMs. Finding the most recent firmware and potential upgrades would be made easier if you knew this.
Step 1: Start your car so that your PCM can start. Your car doesn’t need to be started.
Step 2: At this point, concurrently tap the Source and Info buttons. This will give information about your PCM system.
Note: You may also accomplish it by selecting Info>Option > System Version.
The meaning of Porsche PCM
The central control module for all audio, communication, navigation, and basic vehicle operations in your Porsche is called the Porsche Communication Management, or PCM. The PCM system has a sizable touchscreen display with high resolution for simple and practical usage.
Porsche PCM Connect: What is it?
Volkswagen PCM Apps Porsche Car Connect lets you retrieve car data and remotely handle a few vehicle features when you pair your Apple Watch(r) or smartphone with the PCM system.
How does the Porsche PSM operate?
PSM is an automatic control system that stabilizes the vehicle at the limits of dynamic driving performance and is included as standard. Driving direction, speed, yaw velocity, and lateral acceleration are all continuously monitored by sensors. PSM determines the true direction of motion using this data.
What is a PCM in a car?
The PCM, often known as the powertrain control module, is the brain of your car. Based on the data it receives from different sensors located throughout the car, it controls the engine, gearbox, and other components.
How can I break the Porsche connect?
Please take the following steps to turn off the data connection on your PCM: 7th generation 911, 718, Macan, and 2nd generation Cayenne (all until 2018): Choose PHONE > OPT > SET PHONE > OFF > DATA CONNECTION > DATA CONNECTION
Why is the screen on my Porsche red?
That is the “Red Mist” Porsche Exclusive option. I think it keeps track of blood pressure and pupil size to identify when the mode is on. This is an excellent illustration of how touch screen, fully digital equipment may malfunction severely.
How long does it take an automobile computer to restart?
Until the car has been driven far enough for the computer to analyze the different systems and sensors, the readiness monitors will be in place. Depending on the vehicle, the length of time may change. For all of the computer monitors to entirely reset, it can occasionally take up to 100 miles.
Porsche Car Connect: Is it free?
The majority of the Porsche Connect services have a monthly fee. Depending on the model of your car and the plan you select, the cost of your Porsche Car Connect membership will change; however, the majority of packages are free for the first year or longer. Prices begin at $230 annually.
Will removing the battery reset the PCM?
Will Resetting the Computer After Disconnecting the Car Battery? The response is perhaps. Due to the fact that the car’s computer, or ECU, still has some electricity flowing through it, briefly disconnecting the battery could not solve the problem. After turning off the engine, you should let the equipment more than 15 minutes to reset.
What is the price of reprogramming a PCM?
Do Windows updates annoy you to no end? If so, we’re sorry to break the news to you. The computer in your automobile might need to be updated for optimal performance.
The PCM employs software to manage the car’s systems. It understands, for instance, that you need extra power when driving up a steep hill.
Every potential issue will be considered by the programmers, and solutions will be built in. But just like Windows programmers, they are subject to error or may overlook a specific problem.
Maintaining the performance of your car requires downloading the updates. Most frequently, a manufacturer will publish an update or recall and notify the registered owner of the vehicle that a software upgrade is required.
Almost always, these updates are provided without charge. Simply bring your car to the dealership and schedule some time for the changes to be made.
However, in order for it to function with your car if you bought a secondhand PCM as a replacement (often from a car that was totaled in an accident), it will need to be reprogrammed.
Where you go for the upgrades will determine the cost. Since there are no parts needed, the cost will be normal labor. Depending on the service location you select, costs could range from $80 to $150.
The procedure takes roughly 30 minutes, but you should be aware that most car electricians charge for at least an hour of labor. One of the few instances we’ll suggest a dealership over a mobile mechanic is for PCM reprogramming.
Why is it necessary to reprogram a PCM?
PCM In essence, reprogramming or reflashing is a software upgrade that may be necessary to fix problems with hot or cold starting, rough idle, stalling, or emissions failure.
On a Porsche, what does the exclamation point signify?
Flat tire with an exclamation point inside is the symbol for the tire pressure light. Meaning: You need to check the air pressure in one or more of your tires. Pullover and fill to the proper level, being cautious to look for any damage or leaks

Before the driver even notices them, the sophisticated Night Vision Assist recognizes animals and pedestrians.
Something hides on the side of the road, far beyond the range the motorist can see. In the shadows, it’s impossible to tell if it’s a pedestrian or an animal. The new Porsche Night Vision Assist can be the deciding factor in such circumstances.
The Porsche Panamera’s LED matrix headlights illuminate rural roads at night with light that is as bright as day. The Porsche Dynamic Light System Plus active continuous main beam headlights are standard on the Gran Turismo. The lights are intelligently controlled and may illuminate up to 200 yards into the night. The Night Vision Assist can even see an incredible 100 yards farther into the night, recognizing individuals and larger animals that are not yet visible in the headlights and providing the driver with enough time to react. The Porsche can then brake in time and pass the dangerous location slowly because of the assist system.
The Night Vision Assist operates as follows: The Panamera’s front thermal imaging camera detects the infrared radiation that all live things release. A control unit creates a differential thermal image and transmits it to the instrument cluster’s right “Car & Info” display. When a person or animal is spotted, the thermal imaging camera immediately highlights them in a yellow frame within the normally black and white image. The driver is alerted by instinctively seeing the hue changes. The marking turns red if the circumstance is deemed to be hazardous. In the event of danger, the Porsche Communication Management (PCM) system instantly displays the image from the Night Vision Assist, even if another PCM function is currently in use in the relevant display. The brakes are primed so that, if necessary, the Porsche can stop as rapidly as possible without the driver noticing. The “Speed & Assist” instrument also shows a symbol with a pedestrian or an animal warning to the left of the tachometer at the same time.
As a result, the system is able to discern between people and animals, which is a crucial ability given how unpredictable wild creatures may be. A simultaneous audible caution is given. As soon as the Night Vision Assist recognizes a pedestrian as being in danger, the PDLS Plus briefly flashes the lights three times in their direction (matrix beam function). Although they hardly see the flashes, the driver can see them far better. However, the PDLS Plus avoids flashing the lights at animals because doing so could frighten them and make them a larger threat.
When it is dark, the Night Vision Assist automatically activates and is functional up to 155 mph. In metropolitan areas, the animal warning function is automatically turned off to avoid erroneous alerts brought on by dogs on leashes and similar objects. The Night Vision Assist is constantly left cold by technological heat sources, such as a recently ridden motorcycle.
What exactly does the exclamation point on a Porsche Cayenne signify?
This exclamation point is actually a frontal image of a tire with extremely low pressure, hidden inside of what appears to be a “lampshade.” This light could mean that you need to inflate your tires, but it could also mean that one of many various sensors, including your spare tire, is broken.
How can you tell if your PCM is damaged?
The powertrain control module (PCM), which collaborates with the engine control module (ECM) and transmission control module (TCM) to alter engine timing, the air-to-fuel ratio, and other systems, is in charge of managing a number of your car’s operations.
Here are some typical signs of a PCM failure before we discuss how to test a PCM.
- You have a check engine light on.
- Additionally, the traction control and ABS warning lights can be illuminated.
- For no obvious reason, your fuel economy declines.
- Your automobile struggles to start, needs several tries, or won’t start at all.
- stalling or stuttering while idle
- Your transmission frequently skips gears, shifts erratically, or doesn’t shift at all.
- poor acceleration and performance
These symptoms could also be brought on by other reasons. For instance, low tire pressure can reduce fuel efficiency, and a faulty starter or weak battery can result in difficult starting. But it’s a good idea to visit your PCM if you have two or more symptoms without any other clear cause.
