What Does U1052 Mean?
The module is not receiving valid steering or steering wheel position data over the SCP network. This affects systems that rely on steering input such as traction control, stability control, and variable assist power steering.
Common Causes
35%
Failed steering wheel position sensor or clockspring
25%
Damaged wiring or connector at steering column module
20%
Faulty steering column control module
15%
SCP bus communication circuit fault in steering system
5%
Poor ground connection at steering column electronics
Diagnostic Steps
1
Step 1: Access steering column module using scan tool to verify it is communicating and check for internal sensor faults
2
Step 2: Inspect clockspring and steering column connectors for damage, especially if recent steering wheel removal or airbag work
3
Step 3: Perform steering angle sensor calibration procedure using scan tool if module is responsive
4
Step 4: Test power, ground, and SCP bus circuits at steering column module connector with DVOM
5
Step 5: If sensor cannot be calibrated or module is unresponsive, replace steering wheel position sensor or column control module
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The module is not receiving valid steering or steering wheel position data over the SCP network. This affects systems that rely on steering input such as traction control, stability control, and variable assist power steering.
The most common cause of U1052 (SCP (J1850) Invalid or Missing Data for Steering / Steering Wheel) is: Failed steering wheel position sensor or clockspring
Typical repair costs for U1052 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Stability control and traction control systems may be disabled or function improperly. Variable assist power steering may default to one mode. Warning lights will illuminate but basic steering function remains.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1052 to identify the root cause.
