Subject: Cadillac Deville Starter Disabled Message
Karl tells me: Attempted to start car one morning and the message “Starter Disabled” appeared; not kicking over the car. Car will not start. It request key to be removed and reinserted; however that did not work, nor did any suggestions from the manual work.
Karl, here is something I found on-line that may help you. Let me know if it works or not and if not I will go through a logical deduction to find the problem or contact GM for the solution.
Electrical repairs can be frustrating at times and performing a repair like you did shouldn’t have affected the VATTS/PASSKEY SYSTEM. But since it has here are my suggestions.
1) Disconnect the battery negative cable, turn on the headlamps to drain any remaining power from the computers for 5 minutes. Turn the lights off and reattach the battery cable. This can sometimes reset the computer just like control/alt/delete can with a PC. Then see if the engine will start.
2) Check that the bat 1 and bat 2 maxi fuses are good in the RH fuse block. Remove the starter enable relay and check for battery voltage from the 2 fuses in the start position. Bat 1 is a direct feed while bat 2 goes through the ignition switch and the neutral safety switch. Jumper 1 of battery terminals at the relay with the terminal that goes to the starter and it should engage with the key on. The last terminal is a ground by the instrument panel because the key is being read correctly when it is turned.
3) It could just be a coincidence but the 2 wires coming down from the ignition lock cylinder might have picked that time to go open or it has been happening for awhile and the owner forgot to tell you. So disconnect C202 where all the steering column wiring goes and place your ohmeter on the 2 small white wires coming from the lock cylinder. They are white wires with an orange protective covering and aprox. 20ga. Your meter should show a reading. Turn the key 5-10 times from lock to start and see it the reading stays constant. If the reading goes open when the key is turned you have a wiring problem and need to replace the ignition lock cylinder with keys.
Otherwise you can measure the pellet in the key to double check the value and go to Radio Shack and buy a 1/4 watt resistor as close to the reading as you can. Cut the 2 wires and install the resistor across the 2 wires. Then hopefully the engine will start. There is a 4 minute waiting period between starts if the resistance is incorrect as a theft prevention.
Hopefully one of those suggestions will help get to the bottom of the no-start.
There it is Karl, Good luck and let me know…
Dave
