C0376Front Axle Disconnect
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0376 is not in the published J2012 lists. The number exists at GM, whose bulletin PIP5094 lists it next to transfer case codes such as C0374 and C0387, but no reachable GM document states what it means. The title part decouples the front axle so the front driveline stands still in two-wheel drive. GM handles the front axle actuator of 2007–13 Silverado, Sierra, Tahoe and Yukon under C0379 and blames moisture at the actuator plug. FCA stores such faults as C1463 or C147B: on the 2018 Wrangler the drivetrain module sets C147B-14 when the lock signal of the disconnect stays under 1.19 V for over 500 ms and then leaves the actuator where it is; for Ram 3500/4500 it advises checking the harness 6–8 inches from the plug. If the disconnect fails, 4WD may not engage or release.
