Lost All Electronics

In answer to my previous thread, I picked the car up from the Cadillac dealer today.

My car essentially died at speed, and threw a code for ignition switch and possible stall ... I cleared the codes, and probably shouldn't have.

The dealer scan showed clear codes, but badly carboned up MAF, MAP, IAC, and EGR.

I agreed to have them re and re the MAF sensor and IAC, and to clean the throttle body, MAF, and IAC. They also did a re and re on the EGR valve and cleaned out carbon deposits. The hope was that the car had stalled at speed due to heavy carbon buildup, as it idled quite poorly.

The car was driven, no codes, and fuel pressure was ok. At my request, the car was tested a second time, and it turned off while the technician was in traffic. Codes were pulled, and DIMB1805 ignition switch turned up again.

Basically, the old switch had an intermittant failure on one circuit, so it was removed and a new switch installed.

The car idles much smoother than before, and no shut downs while driving ... not a cheap visit to the dealer, but necessary. Tomorrow, I'm changing the Dexcool, tablets, oil and filter ... something I can do myself.

ted tcb,

Some thngs are best left for the dealer.

I wouldnt want to take any chances with such an unsafe problem as that.

Could have been a lot worse if it had happened at highway speeds,
