1Is this my Problem?

Here are the most common scenarios we hear from our customers experiencing the ATE Teves MK20 & MK25 ABS Repair failure and what you will notice.

ATE Teves MK20 & MK25 ABS Repair

Observable Symptoms:

  • Scanner reads 'Pump Motor Circuit Fault'
  • ABS and Traction Control lights remain constantly illuminated
  • Loss of anti-lock braking capability

A framework for being sure

  1. Pull the ABS fuse and listen. If the endless pump noise stops, the module's motor relay circuit is stuck closed.
  2. Scan for a pump motor circuit fault and clear it. A code that returns within seconds is an internal solder failure.
  3. Measure parasitic draw overnight. More than 500mA with the pump cycling confirms the module is killing the battery.

Now you know for sure you have this problem.

Guide

3Pull the Part

Tools you may need:

  • T20 Torx Bit
  • 10mm Wrench
  • 1/4" Ratchet

Parts you may need:

  • None required for removal
  1. Disconnect the negative battery terminal with a 10mm wrench.
  2. Depress the red locking tab and unplug the main controller connector.
  3. Remove the four Torx screws securing the controller to the hydraulic block.
  4. Separate the controller from the valve block and keep the solenoid pins straight.
  5. Do not open any brake line; the hydraulic unit stays sealed so the system needs no bleeding.

4Fix It

Tools you may need:

  • 60W Soldering Iron
  • Solder Sucker
  • Magnifying Lamp

Parts you may need:

  • 63/37 Leaded Solder
  • No-Clean Flux Paste
  1. Pry the metal cover off the controller to expose the through-hole pump motor pins.
  2. Look for dark rings around the two heavy pump motor pins and the valve coil pins; that ring is the fracture.
  3. Desolder each cracked joint with a solder sucker to clear out the fatigued lead-free solder.
  4. Reflow with 63/37 leaded solder, building a full fillet all the way around each pin.
  5. Reassemble, reinstall, and clear the ABS codes with a bidirectional scan tool.

Skip the headache. We'll fix it today.
