Allure 2002 exhaust (Jake) brake

Posted on behalf of Lou Mindes:

Our 40' 2002 Allure exhaust brake worked intermittently, bad news on a big hill hauling a trailer. One shop thought it could be the relay, that was replaced but did not fix it. Another shop, could not find the problem. With the exhaust brake, the downshift would occur when the bake should engage but the exhaust brake valve would not shut. They rewired from the switch, that changed nothing. Turns out there are two computers. The first one tells the transmission to downshift then that computer tells another computer to close the brake valve. The second computer was bad, they called it a module. Once that was replaced, all worked fine. The reason for posting is to save other coach owners money as the second shop charged almost 20 hours of trouble shooting time.

Thanks Lou. Any idea where the second "module" is located?

Had the same problem with my Cummins ISL 370. Turned oit to be the engine Electronic Control Module (ECM). But he reason the ECM was bad is because the engine brake wires under the valve cover were broken, and shorting out against the engine head, which fried that protion of the ECM.

The original post concerned the exhaust brake (not a Jake brake as the subject line suggests) on a 2002 Allure. That coach typically had a ISC 350 hp Cummins. Your coach has an engine brake (Jake) as you mentioned. Two different animals.
