Jeep Grand Cherokee ABS Control Module Relay Connectors
Jeep Grand Cherokee Abs control module relay connectors
Starting at $70.95, AutoBuffy stocks 1 ABS control module relay connectors from Standard Ignition. This connector is the wiring harness plug that delivers switched power to the ABS control module; when it corrodes, cracks, or loses a terminal lock, the module loses reliable voltage and the ABS system stops functioning safely — often without warning.
Signs your Jeep Grand Cherokee needs a new ABS control module relay connector
- ABS warning light stays on continuously even after restarting the engine
- Traction control or stability control warning lights illuminate alongside the ABS light
- Scan tool shows ABS module communication fault or 'no module response' codes (U-codes)
- ABS pump motor fails to activate during a test stop on loose gravel or wet pavement
- Visible burn marks, melted plastic, or green corrosion on the connector body or terminals
- Intermittent ABS light that flickers or clears on its own — especially after hitting a bump or during temperature changes
Which ABS control module relay connector should you buy for your Jeep Grand Cherokee?
The main decision is whether to buy an OEM-specification pigtail connector, a universal-fit repair connector, or a complete connector kit with pre-crimped terminals and weatherproofing. Matching the exact terminal count and connector housing lock style to your Jeep Grand Cherokee is critical — an ABS module that receives intermittent voltage will throw codes constantly. Check your 2012–2013 fitment guide before ordering.
OEM-Spec Pigtail Connector
Best for
Exact-fit replacement with no splicing guesswork
What you get
Correct terminal count, factory lock tab design, and pre-tinned wires matched to the Jeep Grand Cherokee connector housing
Universal Repair Connector Kit
Best for
Budget repairs when only one or two terminals are damaged
What you get
Loose terminals, heat-shrink splices, and a generic housing — requires careful pin-by-pin matching
Weatherproof Sealed Connector
Best for
High-moisture environments or vehicles with a history of corrosion-related ABS faults
What you get
Silicone-sealed housing and gold-plated terminals that resist road salt, condensation, and under-hood heat
Complete Pigtail with Relay Socket
Best for
Vehicles where both the relay socket and module connector are damaged at the same time
What you get
Combined harness segment covering the relay feed and module plug — reduces overall splice count and labor time

Disconnect the battery negative terminal before beginning, then unplug the damaged connector from the ABS module and relay, using a terminal pick to release any locked pins without breaking the housing. Splice the new pigtail wire-by-wire using color-matched heat-shrink butt connectors, ensuring each joint is fully sealed against moisture. Reconnect the battery, clear stored ABS fault codes with a scan tool, and perform a low-speed test stop to confirm normal ABS self-test behavior.
Frequently asked questions
How much does it cost to replace ABS control module relay connectors on a Jeep Grand Cherokee?
Parts start at $70.95 at AutoBuffy. A DIY repair costs only the connector price plus basic tools. Shop labor for the splice and connector swap typically runs one to two hours; combined part-and-labor cost varies by region and shop rate. Fixing the connector is almost always far cheaper than replacing the ABS module itself.
Can a bad ABS relay connector cause the ABS to fail completely on a Jeep Grand Cherokee?
Yes. The relay connector supplies switched ignition power to the ABS control module. If the connector loses continuity — due to a broken terminal, burnt pin, or corroded contact — the module cannot energize, the ABS pump stays inactive, and the system defaults to standard braking with no anti-lock function. The ABS warning light will typically stay illuminated.
Is it safe to drive a Jeep Grand Cherokee with a damaged ABS control module relay connector?
Normal braking still works through the base brake system, so the vehicle can be driven short distances. However, with ABS non-functional, wheels can lock during hard stops on wet or slippery surfaces, significantly increasing stopping distances and reducing steering control. Repair the connector promptly, especially before winter driving or towing.
How do I know if the connector is the problem and not the ABS module itself on my Jeep Grand Cherokee?
Start with a scan for U-codes indicating loss of module communication. Then inspect the connector for burnt terminals, pushed-back pins, or corrosion. Use a multimeter to verify switched 12V reaches the module power terminals with the key on. If voltage is absent or intermittent at the connector, the pigtail is the likely fault — not the module.
Do I need to reprogram the ABS module after replacing just the relay connector on a Jeep Grand Cherokee?
No. Replacing only the relay connector is a wiring repair — the ABS control module itself is not removed or replaced, so no programming or calibration is required. After the repair, clear any stored fault codes with a scan tool and confirm the ABS warning light extinguishes and the system self-tests normally on the next drive cycle.
How many ABS control module relay connector options are available for my Jeep Grand Cherokee?
AutoBuffy currently stocks 1 connectors across 1 brands including Standard Ignition, covering 2012–2013 applications. Use the year, make, and model filter on the product page to narrow results to confirmed fits for your specific Jeep Grand Cherokee trim and ABS module configuration before purchasing.
