I have a 2002 Chevy Suburban and I am having a problem with the Shift Interlock System. The problem is that I do not need to step on the brake anymore to shift the vehicle out of PARK. I know that the system is supposed to allow you to shift into gear only after depressing the brake pedal, but my vehicle does not do this anymore.
I checked all the fuses in the fuse panel and under the hood and none are blown Also, I removed the dash underpanel and checked for voltage going into the BTSI solenoid (green wire w/white stripe), and there is no voltage going into the solenoid, even with the key ON. This grn/wht wire leads into the steering column by the switch.
Please tell me what I can may check next to solve this problem, or what the problem may be?
