neely76 Posted November 23, 2009 Share Posted November 23, 2009 I've got an '05 Legacy, the cruise hasn't worked since I bought it (Approx. a month). A friend said to reset the computer by disconnecting the negative battery cable and pressing the brake for 30 seconds. To let the power drain and reset the computer. I did this, and the cruise started working....for a little while. Was going down the interstate and it stopped again. Did the same thing (reset the computer) and this again fixed it for a while and again it stopped.... Any ideas? I've checked fuses, no error codes or check engine lights. Just stops working.. HELP!

blicraft Posted November 23, 2009 Share Posted November 23, 2009 Yeah I had the same issue. Eventually it just started working again I didn't really do anything to it. If anybody else knows what the issue is I'd like to know what was causing it. Link to comment Share on other sites More sharing options...
Alicia Posted November 23, 2009 Share Posted November 23, 2009 You know, I just picked mine up a couple nights ago and the cruise control is kinda weird on it. Had a 2+ hour drive home and it worked fine for half the trip then I could set it and it seemed to not hold after varying amounts of time. Hmmm...

Guest PeteAWD Posted November 29, 2009 Share Posted November 29, 2009 I worked in dealerships for many years, not any longer. The techs always told me to NEVER disconnect the battery to reset check engine codes or to correct other issues. In effect, you might be just masking the underlying problem more. In my opinion, just an opinion, the ECM or TCM may need to be reflashed by an authorized dealer. Link to comment Share on other sites More sharing options...
ehsnils Posted November 29, 2009 Share Posted November 29, 2009 The cruise control gets disabled whenever a CEL is displayed, but it may under some circumstances be enough to get a code that doesn't trigger the CEL. If the problem persists I would suggest reading the codes. It may be that a sensor is erratic. Link to comment Share on other sites More sharing options...

NORULZleggy Posted November 30, 2009 Share Posted November 30, 2009 I had this happen to my STI and it is a know cause with the subaru's, there is a switch or plug somewhere under or by the clutch pedal that get busted. Link to comment Share on other sites More sharing options...
rtp Posted January 6, 2010 Share Posted January 6, 2010 This recently began happening in my '05. I have a manual and I have narrowed the issue down to a sensor related to the stick shift. I first noticed it when I went to change the radio station cruise would shut off... a bump or pressure on the stick shift ultimately was the cause. It has gotten worse as of late and I sometimes have to beat the crap out of the shifter to get it to work again. I haven't had the time to dig into it, but there is a sensor in there somewhere that assumes I'm trying to shift even with the lightest of bumps.

ehsnils Posted January 6, 2010 Share Posted January 6, 2010 At least you have processed the hard part of the fault search - which darn sensor is now screwing with me! So the easy way is left - to get a new sensor and replace it. Link to comment Share on other sites More sharing options...
