What Does U0287 Mean?
Communication has been lost between the control module and the transmission fluid pump module. This pump is typically found in hybrid or electric vehicles with dual-clutch or continuously variable transmissions requiring active fluid circulation.
Common Causes
35%
Failed transmission fluid pump control module
30%
Damaged wiring or connector between pump module and vehicle network
20%
CAN bus communication fault on transmission network
10%
Loss of power or ground to pump module
5%
Software issue requiring module reprogramming
Diagnostic Steps
1
Step 1: Check power supply and ground connections at transmission fluid pump module
2
Step 2: Inspect module connector and wiring harness for damage, corrosion, or disconnection
3
Step 3: Test CAN bus communication lines at module using scan tool network diagnostics
4
Step 4: Monitor transmission fluid temperature and pump operation parameters if communication is intermittent
5
Step 5: Replace fluid pump module if all electrical connections and network signals are verified good
Estimated Repair Cost
$400 - $1,200
Parts + labor, varies by vehicle and location
Communication has been lost between the control module and the transmission fluid pump module. This pump is typically found in hybrid or electric vehicles with dual-clutch or continuously variable transmissions requiring active fluid circulation.
The most common cause of U0287 (Lost Communication With Transmission Fluid Pump Module) is: Failed transmission fluid pump control module
Typical repair costs for U0287 range from $400 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Continued driving may result in transmission overheating or inadequate lubrication, potentially causing transmission damage. Address promptly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0287 to identify the root cause.
