U0114

Lost Communication With Four-Wheel Drive Clutch Control Module

Q: Is it safe to drive with U0114?

For normal road driving usually yes, but four-wheel drive may be unavailable. Avoid relying on 4WD in snow, mud, or off-road until it's repaired.

Q: Can I just clear U0114?

It returns if the module still can't be reached. Repair the wiring, supply, or module first.

Network / communication Generic OBD-II Medium

What it means

U0114 sets when the network loses contact with the four-wheel-drive clutch control module, which manages power transfer to the driven axles. The 4WD/AWD system usually drops into a safe default and its warning light comes on; the vehicle still drives, but four-wheel-drive engagement may be limited or unavailable.

Medium

Can I keep driving? Drivable, but four-wheel drive may be limited or off and traction reduced — take care in low-grip conditions and avoid demanding off-road use until fixed.

How to diagnose & fix

Work through it in order

Scan all modules to see whether other units also lost communication.
Check the fuse, power, and ground for the 4WD clutch module.
Inspect the module connector and harness — these live in exposed underbody areas prone to corrosion.
Test the CAN bus wiring to the module for continuity and resistance.
If supply and bus check out, the module is the likely fault.
