Abs light, traction control light, and service stability lights have come on in my 2004 Escalade. hooked up to scanner and it pulls a CO110. Valve stuck


C0110 is abs pump circut problem. The pump is located on the frame rail under drivers seat area. The abs pump comes on to apply brakes as needed for the stability and abs systems. There is a fuse as well as a relay in the relay-fuse center under the hood on the drivers side. please check the fuse and switch the relay with another one that looks the same.

Service stability warning light is on


Thay means that your Stability Control System is malfunctioning. Your vehicle may be equipped with Continuously Variable Road Sensing Suspension (CVRSS) this system controls the ride height (Air Springs) and the stiffness (electronic shocks) of your suspension. Your computer data must be collected and used to help determine the cause of the failure before any repair can begin.

My ABS light is on and off on a 2006 Mercury Mariner. Do I need to do something to get this light to stay off


SECTION 206-09: Vehicle Dynamic Systems 2006 Escape/Mariner/Escape Hybrid/Mariner Hybrid Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 03/29/2005 Anti-Lock Control adobe.gif Printable View (63 KB) The ABS consists of the following components:
  • Hydraulic control unit (HCU)
  • Anti-lock brake control module
  • Front and rear wheel speed sensors
  • Front and rear wheel speed sensor rings
  • Stability control sensor cluster
  • Stability/traction control switch
The ABS prevents wheel lock-up by monitoring the wheel speed sensors and actuating the HCU modulating the brake pressure to prevent wheel lockup. By preventing the wheels from locking up, the driver is able to maintain steering control and stop in the shortest possible distance under most conditions. The traction control system utilizes the same components as the ABS to prevent wheel spin and help maintain vehicle control during acceleration. The roll stability control (RSC) system utilizes the same components as the ABS and the traction control systems and also monitors the steering wheel position sensor and the stability control sensor cluster to assist in stabilizing the vehicle during abrupt maneuvers.
--------------------------------------------------------------------------------------------------------------------------------------
The ABS module is self monitoring. The module will carry out a preliminary electrical check of the hydraulic pump motor by turning the pump ON for approximately 1/2 second either when the ignition switch is turned to the RUN position and the brake pedal is not pressed or when the vehicle is in motion and at vehicle speeds above 20 km/h (12 mph). The ABS module will also carry out a wheel speed sensor self-test by sending a reference voltage to all of the wheel speed sensors through their circuitry when the ignition switch is turned to the RUN position, with or without brake pedal application. If a malfunction is detected in the pump or wheel speed sensors, the ABS module will shut down and disable the anti-lock system. Normal power assisted braking, however, remains.

You may need to have the dealer run a scan test to determine the DTC fault codes. Then go from there. Autozone can't read these codes as tehy are chassis codes. They only can read powertrain codes.

Good luck. please rate.

My car stability system isn't working correctly. how do i go about resetting the car system so it doesn't keep showing up on the car information system. i had an air ride struts installed about 6 months...


Hello: You need a GM or equivalent to scan the system and find out the(s) in the system. After getting the code you have to diagnosis and repair it and then clear the code. The message will go away. There isn't any way to reset the system. IT HAS TO BE FIXED.

Service stability system message appears


i believe your vehicle has air ride suspension in addition to coil springs. i would check the lines that run from the air pump to the air bags. they will black lines that are located near each strut and will go to a pump that is located somewhere iether underneath the vehicle or inside a fender.

97 range rover air suspension problem


Yes, I have worked on these for years, the airshocks get old and seep,weather cracks and wear when they get bad they will burn up the pump, there are several solutions, I have removed the air valves and put stop leak in them and been able to get an extra year out of them, your best bet is to replace the air shocks before they burn your pump up. In my opinion.
