So on Saturday I dyno'd my car. I got the usual errors;
PSM Failure and ABS Failure. No big deal, the car gets confused with the front wheels stationary while the rear wheels are going 90+mph. These errors go away after driving a few feet. But I also got a CEL. I wasn't overly concerned since I was told this could happen, but I would have to take it in to have it cleared.
Well I was driving today, made several stops and each time when I turned the car on I got the CEL. I made an appointment with my dealer to get it cleared on Monday morning, so this annoyance will quickly be over (a reason in itself to get SNAP-FLASH; I can clear the codes myself).
Well after my last stop before I headed home, I accidentally stalled my car

.
Well when I restarted my car the CEL light was gone and didn't come back. What's up with that? Not that I'm complaining, but what could the stall had done to clear this code? Anyone else have something like this happen?
Should I keep my appointment tomorrow anyway and take my CS in?

PSM - Porsche Stability Management
|
 |
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility. |
