How to find an electrical disturbance in 1998 ford expedition


Normally this condition is the result of a poor body ground connection. Testing for this can be deceiving. At the static(nothing on) condition, testing can show a good ground. However when a circuit is excited, it has a determined resistance and a set current flow. If the ground connection to this or a branch circuit is loose, corroded, or broken wire. This will allow just enough connection to show as being good, but not good enough to complete the circuit with the required amount of connection when energized.

Abs light stays on, after changing brakes, 1997 caddy deville


ABS light comes on with ignition then should go off when you start the car.
If abs sensor does not turn off after disconnecting the battery, then there is a real problem, a faulty sensor or ABS malfunctioning.

The abs light stays on and the brake lights stay on even when the ignition switch is off


check the brake light switch. it is located under the drivers side of the dash on the lever the brake pedal is attached to. If the switch is stuck in the on position it will cause all of the symptoms you have described.

Abs dash light stays on all the time except when ignition switch is off


ABS light means that your Anti-lock Brake Systeem is not working. A likely cause is that one of the four ABS sensors is not working or has a broken wire.
You can call an auto parts store to see if they can run a free scan to see if there is a code that may tell you which sensor is bad or some other problem.

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 2002 chevorlet trailblazer LT abs light came on and stays on and turns off if i break and when i let go it goes on it started a couple weeks ago now the light doesnt turn off at all i took the fuse out...


There is no way to turn off the abs light. The system works through the abs module, even if that fuse is pulled the light will remain on.

The brakes will work but you will not have the abs safety working for you.

Have it fixed ASAP!!

ABS brake module sounds like a motor running and won't stop unless battery is disconnected. what is fix?


I would pull the fuse for the ABS hydraulic pump and then put it back in and see what happens. Don't ever recall a pump running. Dealer may need to hook up scan tool for diagnostic fault codes, DTCs.



Principles of Operation
The ABS control module receives wheel speed readings from both front wheel speed sensors and the rear differential speed sensor, and processes this information to determine if an ABS event is necessary. The wheel speed sensor electrically senses each tooth of the ABS sensor indicators as it passes through the wheel speed sensor's magnetic field.
The ABS control module continuously monitors and compares the rotational speed of each wheel speed sensor indicator and, when it detects an impending wheel lock, modulates brake pressure to the appropriate brake caliper(s). This is accomplished by triggering the hydraulic control unit (HCU) to open and close the appropriate solenoid valves. Once the affected wheel returns to normal speed, the ABS control module returns the solenoid valves to their normal position, and normal (base) braking resumes.
The ABS control module is self-monitoring. When the ignition switch is turned to the RUN position, the ABS control module will do a preliminary electrical check, and at approximately 20 km/h (12 mph), the pump motor is turned on for approximately one-half second. Any malfunction of the ABS system will cause the ABS to shut off; normal power assisted braking, however, remains.
Inspection and Verification — Scan Tool Communications Check
  1. Verify the customer concern by carrying out the Drive Cycle Test.
  1. Visually inspect for obvious signs of mechanical and electrical damage.
