What Does U059C Mean?
Invalid or corrupted data is being received from drive motor control module C over the vehicle communication network. This typically applies to vehicles with multiple traction motors or a tri-motor configuration.
Safety Warning
May cause loss of propulsion from motor C, reduced vehicle performance, or unpredictable torque delivery. In multi-motor vehicles, can cause severe handling imbalance or sudden power loss.
Common Causes
40%
Faulty drive motor control module C with internal processor or communication circuit failure
25%
Damaged wiring harness or corroded connectors between motor controller C and vehicle CAN network
20%
Motor position sensor or resolver failure in motor C providing incorrect feedback data
10%
Software bug or outdated firmware in drive motor control module C
5%
Electromagnetic interference from damaged shield wiring or poor grounding
Diagnostic Steps
1
Step 1: Monitor live data from drive motor control module C to determine which specific parameters are invalid (motor speed, torque, temperature, position)
2
Step 2: Inspect high-voltage connectors and wiring harness for motor controller C for signs of damage, overheating, or water intrusion
3
Step 3: Test motor position sensor/resolver output signals with oscilloscope to verify proper waveform and signal integrity
4
Step 4: Check for electromagnetic interference by inspecting shield ground connections and measuring CAN bus signal quality
5
Step 5: Verify software version and check for available updates; if all wiring and sensors check good, replace drive motor control module C
Estimated Repair Cost
$800 - $4,500
Parts + labor, varies by vehicle and location
Invalid or corrupted data is being received from drive motor control module C over the vehicle communication network. This typically applies to vehicles with multiple traction motors or a tri-motor configuration.
The most common cause of U059C (Invalid Data Received From Drive Motor Control Module "C") is: Faulty drive motor control module C with internal processor or communication circuit failure
Typical repair costs for U059C range from $800 to $4,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause loss of propulsion from motor C, reduced vehicle performance, or unpredictable torque delivery. In multi-motor vehicles, can cause severe handling imbalance or sudden power loss.
