00:00What causes the Cessus M failure message to appear in Porsche Cayenne models?

00:05If your Porsche Cayenne is displaying PSM failure message, it simply means there is something off

00:12with its stability management system. This presentation intends to unravel the mystery

00:17behind this warning. Let's start by discussing the basics. PSM in a nutshell. It stands for

00:25Porsche Stability Management. It is an advanced electronic stability system designed for enhanced

00:31vehicle stability and safety. To perform its intended function, PSM relies on a network of

00:36sensors such as wheel speed sensor, steering angle sensor, vehicle yaw rate sensor, etc.

00:43Based on data received from these sensors, PSM detects and mitigates potential loss of traction.

00:49It does that by applying selective braking and adjusting engine power.

00:52Factors that can compromise SEM functionality and trigger the SED warning.

00:571. Sensor Malfunction

00:58To detect loss of traction, PSM relies on a network of sensors. If one of those sensors fail,

01:06PSM functionality will be disrupted. This is something that can set off the SED warning on

01:11the instrument cluster. 2. Faulty ABS Module

01:15The anti-lock braking system plays a crucial role in the overall operation of Porsche PSM.

01:21A glitch in its module can directly impact PSM functionality. This can also cause the PSM

01:28failure message to appear. 3. Low Battery Power

01:32Electricity is essential for smooth PSM operation. If power supply to some of its key components gets

01:39disrupted, the SED warning will appear. There can be many reasons why power supply to your Porsche's

01:44PSM can get disrupted. The most obvious being a weak battery. If you want to have a safe driving

01:51experience, you should ensure the upkeep of your Porsche PSM.
