Question about ignition switch/column lock
From the CLB sticky:
Q What exactly causes this failure?
A When you insert your key into the ignition and turn it to the ON position, the BCM (Body Control Module) sends a command to your Column Lock Motor to "unlock" and then checks a status line to ensure that the steering column is unlocked. If it gets the wrong status, it will display an error message as mentioned above. It can be caused by ECL (Electronic Column Lock) mechanism failure and occasionally by low battery voltage, which sometimes confuses the BCM.
The DIC in my 99 gives me the Pull Key msg when I turn the key to Acc or On. No other DIC functions are active in Acc, just that one error msg.
Does that sound like an ignition switch issue?
Should the key be triggering the column lock relays in the bcm when switched to Acc? (because it is)
