CharlieK Posted June 17, 2016 Share Posted June 17, 2016 2000 Mack CH613, Vin last 6, 126398 Have the 7-2 Code, Parking Brake Switch. Dealer told me it could be one of two switches, sent me both. One is above the clutch, easy to see and get at, the other is above the throttle. This one is interesting, as there are 4 of them exactly alike. His suggestion was to unplug wires and see which one turned on the brake lights... But... My problem did not turn on the brake lights (had someone to follow me to watch while moving). When the electronic malfunction light comes on, the cruise control stops working (like the brake pedal is activated) but the brake lights do NOT come on. When I come to a stop, no moving at all, the light goes out. Start moving again, and get up to 15 mph, the light comes back on again. Its not guaranteed to come on right away either... It often comes on as soon as I hit 15 mph, but sometimes, its an hour later. Anyone have an easy way to narrow down which of the 4 switches it is? The malfunction does not occur at an idle...

CharlieK Posted June 17, 2016 Author Share Posted June 17, 2016 okay, and as soon as I posted that, the thought occurred to me to set the cruise with a bumped up idle, and unplug wires to see which one shuts it off.... Any ideas other than that? Quote Link to comment https://www.bigmacktrucks.com/topic/45711-7-2-code-2000-mack-ch613/#findComment-336999 Share on other sites More sharing options...

Joey Mack Posted Monday at 10:41 PM Share Posted Monday at 10:41 PM Oh.. well sir, i didnt take in to consideration that you are outside if the U.S. please forgive me... I have zero experience on your truck, i would just be probing and testing the switches to understand which one does what.

Joey Mack Posted Monday at 10:42 PM Share Posted Monday at 10:42 PM Maybe your name Redeyedog would give it away. I watched a movie called Red Dog, from your homeland.. 🍻 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45711-7-2-code-2000-mack-ch613/#findComment-569604 Share on other sites More sharing options...
RedEyeDog Posted Wednesday at 02:54 AM Share Posted Wednesday at 02:54 AM Thanks Joey, Yes about the red dog, but, the eyes on my Bulldog on the hood of my CH has Red LED lights in it, so when lights are on, so are his eyes 👍 I was hopeing CharleK had an answer to his problem. Like it was such n such switch, then I could find that switch in this Quantum. Being French, they put things in all different places than the CH. I don't know if I should copy CharlieKs post and start a new convo about this problem. What ya think mate !
