Hello, my name is Jordi and I write from Barcelona (Spain). In 2012 I purchased a 2005 Corvette C6, automatic transmission (34.000 miles). The car runs great until 2014, where appeared a malfunction when starting the car, with the message "Service Column Lock". I read on the internet that is a generic problem in these models 2005 C6, caused by a module at the steering column, causing the inhibition of engine starting.
It seems that the cause of the problem is a module composed of a low quality plastic, ignoring at current date if GM has replaced this part of better manufacturing material. I add an entry to an owner of the same model that explains the problem: The lock is mostly made of poor quality plastic and the actual pin that engages the locking ring is moved in and out via a worm screw that passes thru a block that trips a microswitch. The plastic worm screw binds in the plastic block, the drive motor current starts to rise and the computer detects the overcurrent and stops the process and issues a "Service Column Lock" DTC.
Anyway, I read it that there is a “bypass” module that inhibits the signal sent by the defective part and allows starting the engine without problems.
But I have my doubts and questions: This so-called "bypass" module is a definitive solution to the problem? It can cause undesirable effects on the electronics of the car or even affect active safety? Is there another solution of this problem by GM for 2005 C6 Corvettes ?
Thank you very much,
JORDI
