I have a 2006 outback 2.5I and the cruise control will not come on. The cruise light on the dash does not come on when the key is turned on. I have checked all the fuses i could find and all are good. anybody have any ideas?

That's a strange one; first time I can recall a fault where the indicator lights, which are LEDs and driven by the combination meter microcomputer, don't come on.

I have checked all the fuses i could find and all are good.
Do you mean you checked all the fuses in both the engine and dashboard fuse panels, or do you mean you checked those fuses you could find that you believe are related to the cruise control?

If the latter, which fuses did you find and check (they're identified in the Owners Manual, by number)?

How did you check the fuses?

Did you try running the cruise control even though the indicator lights aren't on? (E.g., get up to a safe cruise speed, press the button to turn on the cruise control, and then flip the lever down momentarily to "set" the speed.) Did it work even though the lights indicator didn't come on?

Is the trip meter (in the odometer area) showing the current trip mileage, or is it showing what looks like an "Er" followed by two letters.

I checked all the fuses in both panels. none of the fuses are labled for the cruise control. I checked the fuses with a test light, and all had power on both sides. I did try to set the cruise without the light being on and at several different speeds but could not get it to work. The trip meter is is showing the correct trip mileage and reset to zero when the reset was pushed.

That's a very good possibility.

Did you also not have any cruise warning lights come on when the ignition key was set to On but the engine was not started? (They should come on for a few seconds, and then go out.)

It would be interesting to know if when there's a break in the clockspring that opens the circuit through that remaining path, the instrument panel cruise control lights don't come even when the ignition switch is turned to ON.

I also thought it could be the contacts in the steering column causing an open circuit but with the airbag I am not comfortable taking it apart. My dealer has agreed to fix the problem, i will take it in next monday and suggest they check the clock spring. Since they are not a subaru dealer i hope they have a good mechanic.

Interesting diagnosis. All the switches in the cruise control switch are "normally open", so they're not likely the problem. There is a connection that goes through the clockspring and a string of resistors inside the switch housing. Perhaps if there's break in that circuit the CC won't work AND the instrument panel lights won't come on when the key is at On (but before the engine is started).

Will be looking forward to your update . . .

No power measured at the switch itself could be caused by a bad roll (clockspring) connector, which is "upstream" of the switch.

This is an interesting situation, especially the fact that Cruise lights don't come on when the ignition is turned to ON for the warning light check, which I thought would work even if the connections to the switch were defective. I don't recall any cases like this before, so please do continue to keep up informed.

Great news. Your cruise is back in operation, and we have confirmation that the "lights out" symptom (when the key is set to ON and other warning lights are on) was related to the broken connection (clock spring) between the cruise control module (ECM) and the control switch at the steering wheel. Something new learned, again.

Thanks.
