SOURCE: abs system malfunction

I WOULD RECOMMEND THE ABS BE SELF TESTED BY A FORD DEALER, A FAULT CODE WILL BE PRESENT THAT WILL LEAD IN THE DIRECTION TO REPAIR THE PROBLEM.
THE 2nd PROBLEM SOUNDS LIKE WARPED FRONT BRAKE ROTORS.

A 2004 chevy tahoe instrument cluster parking brake light is red,is that due to the overlay or a bulb


If your amber ABS lamp and the red "parking brake" warning lamp illuminate together without any prior pump constantly running problem; the pump motor wires are most likely broken.
The heat shrink tubing that seals the red/black power leads to the motor may have allowed water to enter. The copper conductor turns into a powdery green copper oxide over time due to electrolysis as a small current is applied to the motor all times (even when vehicle is off). The wires will look perfectly intact on the outside even though the copper conductor has been destroyed. The associated error codes will either be C0267 or C0268.
Initial problems will be an intermittent amber ABS and red BRAKE lamp illuminating simultaneously. Over time, the lamps will stay on constantly. In any of the circumstances, you have lost your ABS at all times... even when the lamps are off during the intermittent stage of the system failure.
Dealer specifies pump assembly must be replaced. Not necessary.
The wires can be resoldered to the motor terminal block and resealed with new heat shrink tubing and sensor safe silicone. Do not remove the motor from the pump housing as it is difficult to align the eccentric cam on the motor shaft with the pump mechanism.
This is a common problem that can be solved by resoldering the pump power leads. If the pump runs all the time and the red "BRAKE" lamp has illuminated after pulling the ABS fuse or unplugging the motor; the EBCM (ABS control module) will have to be rebuilt. This can be done for $100.
Both pump motor failure and EBCM failure can be repaired without costly replacement

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

Constant running under hood after engine is shut off. It's on drivers side rear of fuse block?


That is likely your abs pump motor that is still running. The fix is to replace the abs control module in that same location(black box).

01 Suburban with abs system. abs light came on


A relay controls the ABS motor. You can trace the wires running to it. The next time you shut the engine off unplug the relay. If that shuts it off get a new relay for the old one will not open its circuit to shut off the motor to the ABS motor
