C1611 on Genesis by model: symptoms, diagnosis and fix
An electrical short circuit can develop inside the Anti-lock Brake System (ABS) hydraulic control module. Because the module is always powered, the short can cause an engine-compartment fire whether the vehicle is parked or being driven, even with the ignition off. Genesis recalled certain 2019-2021 G70 vehicles under NHTSA campaign 21V-161 (Genesis recall 007G); owners were told to park the car outside and away from structures until repaired. This is part of the broader Hyundai/Genesis ABS-fire recall family. The remedy installs a fuse in the ABS module wiring to prevent the short from igniting a fire.
Common Symptoms
- Burning or melting-plastic smell from the engine bay
- ABS / brake / traction-control warning lights illuminated
- Smoke from under the hood while parked or driving
- Blown fuses related to the ABS circuit
How to Fix
Confirm the VIN against Recall 21V-161 (007G) and have the free remedy performed — dealers add a multi-fuse to the ABS module's power supply so a short can't start a fire. Until repaired, park outdoors away from buildings. If the ABS warning light is on or the module has already been damaged, the hydraulic electronic control unit (HECU/ABS module) is inspected and replaced as needed.

Frequently asked questions
What does C1611 mean on a Genesis?
C1611 stands for "ABS Control Module Internal Fault." C1611 is a brake-system code indicating an internal fault within the ABS control module itself — the unit ran its self-checks and found that one of its internal electronics or processors isn't working correctly. Because the fault is inside the module's own hardware/firmware, it's usually not something you can fix by replacing an external sensor. The module typically disables ABS, traction control, and stability control when this is stored, while normal hydraulic braking remains. It generally points to a failing or failed ABS/EBCM unit, though power, ground, and software issues should be ruled out first. On Genesis it is documented across 1 model: G70.
What are the most common causes of C1611?
The most common causes of C1611 are: Failed ABS/EBCM control module (internal electronics), Low or unstable supply voltage to the module, Poor power or ground connections at the module, Corrosion or moisture intrusion in the module connector, Outdated or corrupted module software requiring reflash, Internal solenoid or pump driver failure within the unit. The specific cause varies by vehicle.
How much does it cost to fix C1611 on a Genesis?
Repair costs vary widely with the root cause and Genesis model; each issue on this page carries its own estimate where one is published.
