chevy3500 Posted May 20, 2023 Report Share Posted May 20, 2023 2000 Kenworth t2000: My engine brake wont activate, switches are on steering wheel (smart wheel) and has indicator lamp on upper dash. Neither the light or actual engine brake will work, any one know where to start looking? could not find a fuse that that was labeled for it in fuse box, there is a relay labeled "ABS engine brake" but replaced that with known working relay and no change. This seemed to quit working while driving and had been working fine. Any help would be appreciated Thanks! Quote Link to comment Share on other sites More sharing options...
Darryl&Rita Posted May 21, 2023 Report Share Posted May 21, 2023 Jake needs a closed contact on the clutch pedal, a closed signal from the air brake pressure switch, a power signal from the dash On/Off switch, and a signal from the ECM that the throttle has no, zero, none pressure on it. The power signal appears to be getting through, as the dash indicator...indicates. Our T2 has problems with the air brake switch and corrosion. At least once a year, reach up under the dash from the ground. Wiggle the wires, good for another year. The first indication of corrosion is the cruise control randomly dropping out.

Case20hp Posted May 21, 2023 Report Share Posted May 21, 2023 On my 09 T660 the clutch pedal doesn’t return all the way to the top all the time. If I pull it up with my foot then my jake and cruise work. My issue is the pedal needs to be lubricated under the dash. Quote Link to comment Share on other sites More sharing options...

chevy3500 Posted May 23, 2023 Author Report Share Posted May 23, 2023 FYI the cruise seems to work fine, "The power signal appears to be getting through, as the dash indicator. indicates." quote from Daryl, but dash indicator doesn't come on.

Darryl&Rita Posted May 23, 2023 Report Share Posted May 23, 2023 My bad, I misread that the lamp was working. If the cruise is working, it has to be the switches on the steering wheel, or the connections to the ECM. The clutch switch and brake switch would also affect the cruise.

Darryl&Rita Posted May 23, 2023 Report Share Posted May 23, 2023 You might get lucky, hit all the switches over and over. KW's tend to get corrosion in the weirdest places, and that plays havoc with the controls. I'm hesitant to recommend contact cleaner around the plastic of the steering wheel, but it can be useful, if you're very careful.

chevy3500 Posted June 5, 2023 Author Report Share Posted June 5, 2023 Thanks Scrap and Darryl. I've been on vacation so haven't looked at it much, did take the switch out but didn't see any obvious issues. Its a small module with 4 micro switches, (2,4,6 cylinders and off) can hear them clicking on and off, I know that don't mean anything, but maybe with the Scraps manual I can test it. Did attempt hitting switches repeatedly, as you suggested but no luck, Darryl. Before starting to pull things apart, where is the electronics module located? under dash or on steering column. Thanks again! Quote Link to comment Share on other sites More sharing options...
