U0110

Lost Communication With Drive Motor Control Module A

Q: Is it safe to drive with U0110?

Often no — the drive motor control module runs electric propulsion, so this code can leave the car in reduced power or unable to move. Have it diagnosed before driving, especially on a hybrid or EV.

Q: Can I just clear U0110?

No. High-voltage drive faults return until the wiring, power, or module problem is fixed, and clearing it can mask a serious propulsion fault. Repair the cause first.

Communication network (hybrid/EV drive) Generic OBD-II High

What it means

U0110 means another module has stopped receiving data from the drive motor control module — the controller that runs the electric traction motor on a hybrid or EV. Because this module drives the wheels electrically, losing it commonly cuts propulsion, forces reduced power, or stops the car from entering ready/drive. It usually points to a wiring, power/ground, or bus fault at the controller, or a failed module — this is a high-priority code, not a comfort glitch.

High

Can I keep driving? Often not drivable normally — losing the drive motor controller can cut electric propulsion, force reduced power, or prevent the hybrid/EV system from starting.

Common symptoms

What you'll notice

Hybrid/EV warning lights or 'service powertrain' message
Loss of electric drive, reduced power, or limp mode
Vehicle won't move or won't switch to ready/drive
Other modules report lost communication with the drive motor controller

Common causes

Most likely first

Damaged or corroded CAN wiring/connector at the drive motor control moduleLikely
No power or ground to the drive motor control module (blown fuse, bad ground)Common
Internally failed drive motor control moduleCommon
Bus fault taking down the segment the controller sits onLess often

How to diagnose & fix

Work through it in order

Scan all modules; confirm whether only the drive motor controller is missing or a whole bus segment is down.
Check power, ground, and fuses feeding the drive motor control module.
Inspect the CAN wiring and connectors at the module for damage, corrosion, and moisture.
Verify CAN-High/CAN-Low resistance and voltages to rule out a bus wiring fault.
If wiring and power are good and the module doesn't respond, replace/reprogram it per the service procedure, then clear and re-test.
