What is the C0265 error code

The ABS EBCM anti-lock brake module is failing causing problems with the ABS pump running constantly, also will drain your battery.
  1. Remove the ABS fuse to prevent ABS motor burn out.
  2. You can still drive your vehicle with the module removed.
  3. We recommend covering the exposed surface of the hydraulic control unit with aluminum foil to keep out water and dirt.
Common Failures:
  • ABS Pump Always Running
  • Codes: C0265, C0267, C0268
  • Pump Motor Circuit trouble code
  • Power Relay trouble code
  • Valve Relay Trouble code
  • Dump Valves (solenoids) trouble codes
  • No Communication
  • Intermediate power loss

Abs light on on the dash and a motor under van stays on when key is off

the motor you are hearing could be the abs pump. abs light will not come up on a code reader for engine as its classed as body part. if it is this pump then the system is faulty and the pump running can mean that it has a broken fin inside you cannot fix this part and another abs pump will be need to fix this.

I have a dodge caravan that has the ABS and the BRAKE light on the pedal is rally hard but it goes away once in a while for like a day and all over again

Dodge used an ABS system for 2 years that didn't have a vacuum booster. Instead it used ABS pressure from the pump motor for the power brakes. This is the system you have. The ABS pump is mounted on top of the transmission. Is the pump running when the pedal is hard to push? Sometimes the pressure sensor in the ABS module will go bad and the pump won't run. You will get a hard pedal and the ABS light and the BRAKE lights will be on. The code in the ABS control module will be LOW BRAKE ACCUMULATOR PRESSURE.

Can you explain a scan code of c1218 and code c1243

C1218 - Pump Motor Circuit Shorted to Voltage or Motor Ground Open
C1243 - BPMV Pump Motor Stalled /These are codes relating to your ABS system(antilock braking). It looks as though you may have a ABS system pump that has burned out. Replace the pump, not the module.

DTC trouble code 28 TCS C 1214 HC

The C1214 error is related to the electronic brake traction control module (EBTCM) BPMV pump motor relay contact circuit open. Check the 40A ABS Maxifuse in the underhood electrical center. if blown change it, clear the DTC and if it blows again check for a short in the 1642 line or internal short in the BPMV.
When an ABS/TCS operation is required, the EBTCM activates the pump motor relay and battery power is provided to the pump motor. DTC errors are either H (history) or C (current) I usually clear the history and see if it sets again later.

Abs light is on

Locate and pull the ABS pump fuse located in the power distribution center under the hood and CHECK IT TO SEE IF THE FUSE IS BAD. Basically you are looking for a fuse box with large amperage fuses and some relays. Look along the fender well in the engine compartment relatively close to the battery. It is a 60 amp fuse in most instances and should be clearly labeled "ABS" in the large fuse box with other similarly oversize fuses used for other high power subsystems. 
 All ABS systems are designed so that the solenoid valves in the ABS brake manifold are in safety "bypass" mode when powered down or when the ABS control module has been removed. You will have standard everyday power brakes no different than brakes built without the ABS system.

The ABS system will perform a self check once you exceed 5 MPH and the "ABS" and "brake" lamps should turn off. During this test, the controller runs the pump motor and briefly operates all of the valves. This ABS "self-test" is performed every time you start and drive.

EBCM is short for "Electronic Brake Control Module" It is the advanced computer than controls the electric motor pump and valves of your ABS system.  Burnout of the motor is very rare however. A MOSFET transistor in the EBCM (Electronic Brake Control Module) has failed, can cause the pump not to perform.

Pump motors generally do not fail, but when they do, the culprit is usually worn-out brushes or corroded electrical connections. In a worst-case scenario, your motor is beyond repair. It is bolted directly to the hydraulic assembly- a cast aluminum brake fluid distribution hub with 5 or 6 brake lines branching off of it and wiring harness.

I hope this helps before you get your hands to dirty. In short check all the electrical connections first. Try running a hot wire to the pump motor first to see if it runs and if it does, then it's not the motor and could be a easier fix by changing the (EBCM).
