No Cruise!

Its an 01 DBW 5.3 I have power in all places but the Resume\Accel wire. The TCC and brake signal also check out. I checked at the TAC module plugg and the PCM plug. Any ideas or do I have a fragged TAC? Jay

Re: No Cruise!

What is this in? You said that the brake switch checked out, but did you check the brake light bulbs? The cruise has to see the resistance of at least one bulb at start up for it to work, which is usually the third brake light, but in conversions will be the regular brake lights, which is why you can't run just LED brake lights. Are you using LEDbrake lights?

Re: No Cruise!

Its in my 87 Gitmo. The bulbs are good. Although the feed is wired through a relay. So it may not be seeing ground. I will check it.. Jay
