SOURCE: Dodge Gr Caravan error codes U0155, U110C, U0140

you are incorrect on your code read. u0155 is lost comm with IPC, u110c is no fuel read, u0140 lost comm with BCM and can all be fixed with a new BCM.

SOURCE: How I reset the 'check

  • Look to the right side of the hood release handle on the driver's side of the Toyota and find a port. Plug the OBD II scanner tool into this port and turn the key in the ignition to the "II" position.
  • Press the scroll buttons on the scanner to go through the items on the menu. Find a command that says "Erase," and then press it.
  • Watch for the main menu to appear, or wait until you receive a scanner message reading "Command Sent." Unplug the OBD II scanner tool and turn on the engine. Inspect the dashboard to determine if the check engine light is off.

    SOURCE: My ABS light is on

    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.

    • Base brake system
    • Brake booster vacuum hose
    • Hydraulic control unit (HCU)
    • Steering components and suspension components
    • Tire size
    • Wheel speed sensor ring
    • ABS module
    • Battery junction box (BJB) fuse(s):
      • 19 (40A)
      • 22 (40A)
    • Brake fluid level switch
    • Brake pressure transducer
    • Smart junction box (SJB) fuse(s):
      • 6 (15A)
      • 34 (5A)
    • Stoplamp switch
    • Wheel speed sensor
    • Wiring, terminals or connectors

    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.

    Check engine stay all the time 2005 mercury mariner


    There is a lot of things that cause a engine lite to stay on.

    Here is just a few things, that will have engine light stay on:

    Service is due, some cars have that automatically do this when time for regular service.

    Breaks, Some cars have a sensor that after a certain range on your pads, it triggers the service Light.

    Oil Low, or water/antifreeze low.

    Emission problem, Like fuel filter needs replacing or possible 02 sensor not working ( part of your Cadillac converter)

    Battery not fulling charging, or alternator not putting out proper amps. etc,,

    This list can go on and on, most the time if you have low oil, or break issue, there is separate warning lights for that.

    Here is what I think, sometimes when you have something wrong with your car, if you checked your oil level, water/antifreeze level, breaks seem good, and all your other fluids are good, and your car is running good and as normal, what best to do, is take it in and have them put it on there computer, this will tell you if there is something your over looking, by normally a code that comes up on there system. Sometimes the code will come up on there computer and not on your dash warning lights. Auto Zone, normally can do this for free with there hand held computer and tell you what comes up and what to check out. And all Garages if everything is ok, can with computer turn your engine light off if everything is ok. But for sure get it checked, and don't just assume it is a faulty engine light coming on, most the time there is a reason. Thanks Mike
