Get your suspension checked out. That's your automatic stability control.
Just took my car in for the ASC OFF service required! On dash board So they told me to try the brake stop switch so i paid the $140 and took it home an purchased and installed the switch didn’t solve the problem. Took it back to the dealer they called back and told me that the after market alarm that the dealer installed was wired to the ETACS brake control module and it was faulty causing brake system fuse to go out. I didn’t even know it had an alarm since I purchased the DE modle. I guess my dealer installs alarms on all its cars to make surf noone takes them off the lot. I get ready to pick up my car and they wanted me to pay another $140 for tracking down the problem. I told them that didn’t track down the right problem to begin with. So they gave me my car the second time at no charge.
I have this EXACT same issue. ASC Off Service Required and my Cruise Control is not working either.
My 07 Outlander flashed up ASC problem and went into limp mode. Unless the braking system was acting up, the engine appeared to cut power but i could crawl home since it happened just round the corner from my home. Thanks to the advice in this forum i disconnected the battery for 10 minutes or so to re-set the onboard computer. After re-connecting the battery I turned the key in the ignition half way to turn the electrics on. At this point i held the ASC button (below the steering wheel on the driver window side on my version) down for several seconds until ASC OFF came up on the dash. Then i went ahead and started the engine. Like others have discovered in this forum - the car runs totally fine apart from the large warning displayed all the time on the dash display, flashing 4WD / Lock, SERVICE REQUIRED, ABS etc, etc. It beeps a lot in the first couple of minutes of driving but then goes silent. It seems that one or more of the ABS sensors are dirty, maybe a sensor is broken. No way to know until my mechanic can do a computer / diagnostic test. Anyway if a sensor is dirty it's an easy job for a mechanic to remove, clean and replace. So it means driving the car without ASC and ABS. Neither of these are needed except for the rare occasions one has to emergency brake or swerve violenty. Changing from 2WD to 4WD seems to still be working fine from the feel of the wheels on gravel. After reading codes I found that one of my ABS sensors was bad. This guide helped a lot. https://www.youcanic.com/guide/mitsubishi-asc-system-disabled
