Dealer said I need a new ABS module

  • 70,000 MILES
When driving for awhile on and off the brakes they will not release fully. There is no check engine light on. And after awhile they seam to be OK. This doesn't happen all the time the dealer said I need a new ABS module.
Do you

Replacing the module isn't too bad. Just take your time and make sure nothing gets damaged.

First, here is a link that shows in general how it is done. You can use this as a guide.

Here are the directions specific to your vehicle for replacement. The pics below correlate with the directions.

1. Clean any debris off the mating surfaces of the HCU and ABM.

CAUTION: When installing new O-rings or solenoid valve stem seals, do not use any type of lubricant.

2. If the seals (1) on the solenoid valve stems (2) are not new, replace them all. Each of the solenoid valve stem seals must be new to keep out moisture and debris; do not reuse solenoid valve stem seals.

3. Replace the pump/motor connector O-ring (1) if it is not new. Be sure the O-ring is properly seated in the mounting groove (2).

4. Align components and install the ABM (1) on the HCU (2).

5. Install the four screws (1) attaching the ABM (2) to the HCU. Tighten the mounting screws to 2 Nm (17 in. lbs.).

CAUTION: Before installing the ABM harness connector on the ABM, be sure the seal is properly installed in the connector.

6. Insert the ABM wiring harness connector (2) into the socket of the ABM (1) and close the cover, locking the connector in place.

7. Connect the negative cable on the battery negative post.
8. Hook up the scan tool to initialize the ABM and perform the following:
a. Clear any faults.
b. Perform the ABS Verification Test and road test the vehicle. See: Brake Bleeding > Procedures

I hope this helps. Let me know if you have other questions.

Check out the diagrams (Below). Please let us know what happens.
