CADILLAC DEVILLE BATTERY PROBLEM

1992 Cadillac Deville • 135,000 miles

Hi I am looking at a chiltons manuel to diagnose a cruise control problem. I reposted sorry. But Is a speed sensor on the 1992 cadillac deville related to the cruise control. I have checked the fuse it was good. Their is no leak in the vacuum. I changed the cruise lever out. I checked for power it has power. I bought a servo on ebay that was supposobly in working condition. Where is the stepper motor located. From the sounds of it. It is the thing that attaches to the throttle cable and the cruise cable. What is a transducer and how do you test it. Also is their a way to test the cruise servo. Thanks.

Their is 12.2 volts going to the pink and black wire.

Hey their is 12.2 volts going to the pink wire

That means you have battery voltage. Turn switch on and test the Grey wire for battery voltage.

Ok. I tested it I put the positive wire on the grey and put the negative on the black wire. It read 0.00 voltage. I also put the red volt meter wire on the grey and it still showed 0.00

Did u check for voltage on both sides because if power is going through the connector to the lever and the yellow light doesnt light then the lever is faulty.I dont know why your not setting codes 60 to 67 to help u diagnosis the system.

No, you don't test this way. The other probe should be grounded to body, not the black wire.

I was testing the ground to the switch and voltage at the same time khlow.

Ok so I did what khlow and what cadieman said. I grounded one probe to the bady the grey wire came up with 0.01v. I put everything back together. I tested both sides like you said and their was power. I also hooked the two connectors and it was 12 volts on one side and 0.01 on the other and I flipped the connector on the other side and it wasthe same. So their is voltage going to the connector I would assume.

I know there is voltage coming to the connector because your reading voltage from the pink and black wires. This tests the voltage on the pink and it tests the ground to be good. Just test the opposite side of the connector the same. Look like blue and yellow and black stripe. Do u read voltage their going to
