Mbmaring Posted April 23, 2008 Share Posted April 23, 2008 (edited) I have the engine malfunction light on and I figured out hoe to check the code and it is a 4 2 code and according to the owners manual it is fan clutch output fault. What does that mean?It is a ch 613 1999 model with a e7 400 hpOne thing I noticed to is that the AC clutch is not getting any power to engage.

Mackpro Posted April 23, 2008 Share Posted April 23, 2008 If this an E-TECH engine ( most 99 engines are), check fuse 41 in fuse box under hood ( on firewall,above drivers side front tire) If its good, unplug fan clutch solenoid and turn key on and you should have 12 volts at on of the 2 pin on the harness side plug.

I unpluged the fan clutch solonoid and it still blew the fuse. I wonder how I could trace down the wiring short? could it be a sender causing the problem?

I have had this problem before. I'll look at the wiring diagram in the morning and let you know. Quote Link to comment Share on other sites More sharing options...

I'll look at the wiring diagram in the morning and let you know.I enclosed a wiring diagram for fuse 41. We had some problems with wires rubbing and shorting to ground on to of trans. There are 2 plugs onto of trans, 1 says pto and the other is torque limit, make sure those wires are not shorted to ground. Quote Link to comment Share on other sites More sharing options...
