Diagnostic Steps
1
Step 1: Research manufacturer-specific information for U1152 to identify what 'Experimental #3' refers to in this vehicle
2
Step 2: Use scan tool to identify all modules on SCP network and compare to vehicle configuration/option list
3
Step 3: Check for manufacturer technical service bulletins (TSBs) regarding this code and software updates
4
Step 4: Verify vehicle configuration matches installed modules; check if code appears after module replacement or programming
5
Step 5: If feature is not applicable to vehicle, code may be ignored or cleared through dealer-level reprogramming
Estimated Repair Cost
$100 - $500
Parts + labor, varies by vehicle and location
This code indicates missing or invalid data for an experimental or manufacturer-specific feature on the J1850 SCP network. The exact function varies by vehicle make/model and may relate to prototype features or special equipment.
The most common cause of U1152 (SCP (J1850) Invalid or Missing Data for Experimental #3) is: Prototype or experimental module not present or failed
Typical repair costs for U1152 range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Typically no safety impact as this relates to experimental or optional features. Vehicle should remain safe to drive with normal functionality.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1152 to identify the root cause.
