Hello from the great white north in Canada's Yukon Territory...I have a 2004 Twinpeaks 700 and last weekend the 2wd/4wd ligts started flashing back and forth at two second intervals ans it won't shift out of 4wd....I realize the two second flashing means a problem with both the selectable 2wd/4wd actuator and the engine brake actuator...it just seems strange that they would both go at the same time...I could live with the flashing lights but I really want to be able to shift it into and out of 4wd so I can drift it into the corners without hooking up so much....I've taken both actuator covers off and they are clean and dry....any idea's would be greatly appreciated...Thanks for listening!!![img]i/expressions/face-icon-small-confused.gif[/img]

 

Remove the seat and locate the Controller (little black box with one large connector). Try re-plugging the connector with the ign key off. If there is no mechanical failure, that should stop the flashing and 2/4WD function should resume normal operation.
