Will 84778359 fit my vehicle?

To be sure, match the part number on the label of your old module, or send us your VIN — we'll confirm compatibility before you order.

Does this ABS module need programming after installation?

In most cases, yes. General Motors ABS control modules usually need to be programmed or configured for your vehicle after installation using a dealer-level scan tool. The module ships unprogrammed — programming is done by your dealer or a local repair shop.

Is there a core charge?

No. There is no core charge on 84778359 — you don't need to send your old part back.

What are the symptoms of a bad ABS control module?

Common signs are an ABS or traction control warning light, stored ABS fault codes, ABS activating at low speed, or loss of communication with the module. Reading the fault codes with a scan tool is the best way to confirm the module is the cause.

Where is the ABS module located?

On most cars and pickups, the ABS control module is mounted on the brake hydraulic unit (modulator) in the engine compartment, usually near the brake master cylinder. The electronic module bolts onto the hydraulic unit and connects through one main electrical connector.

Can I drive with a bad ABS module?

Your regular brakes will still work, but anti-lock braking, traction control and stability control may be disabled, which increases stopping distance on slippery roads. We recommend repairing it as soon as possible.

How much does it cost to replace?

84778359 costs $479.00 at Parts Finder Q. Installation and programming are done by your local repair shop or dealer — ask them for a labor quote.

What warranty and shipping do you offer?

84778359 comes with a 365-day warranty. Orders placed before 7 PM EST ship the same business day, shipping is free on orders over $199, and local pickup is available at our South Carolina warehouse.
