What does u0401 mean on the ECM?
Code U0401 indicates one or more modules onboard the vehicle has received invalid data from the ECM. Code U0401 is typically caused by one of the following: Sometimes U0401 can pop up intermittently, or it can result from a dead battery. This is especially true if the code is a history code and not current.
What does the engine control module code u0401 mean?
What does code U0401 mean? Code U0401 stands for Invalid Data Received from ECM/PCM. The engine control module (or powertrain control module) is the computer than manages engine operation. The engine control module (ECM) receives input from sensors throughout the vehicle.
How much does it cost to diagnose an u0401 code?
The cost of diagnosing the U0401 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. Engine Light ON (or Service Engine Soon Warning Light)
What to do if u0401 is the only DTC stored?
If U0401 is the only DTC stored, the ECM module itself should be checked. The easiest was to start this process is by attempting to communicate with the ECM using a diagnostic scan tool. Once connected to the vehicle, the tool acts like just another module on the network. It can be used to address the ECM module.
