U1120 on Dodge

Manufacturer code: on Jeep and Dodge, U1120 means a module lost the wheel distance message it expects over the vehicle network

Severity: Inspect soon

Jeep and Dodge owners report U1120 with ABS, traction and brake warnings and a speedometer that drops to zero, so the anti-lock and stability systems may not be working. Have it diagnosed soon.

It gets more serious if:

Stop: Stop in a safe place and have the vehicle towed if it loses power or the brake warning stays on. A 2014 Jeep Cherokee owner lost power on the highway with U1110, U1120 and U0121.
