What Does U1094 Mean?
This code indicates missing or corrupt data for experimental diagnostic parameter #2 on the J1850 SCP bus. Experimental codes typically relate to development features, manufacturer testing functions, or pre-production vehicle calibrations.
Common Causes
35%
Module software version mismatch or outdated calibration
30%
SCP bus communication intermittent due to wiring issues
20%
Module not configured or programmed to transmit experimental data
10%
Failed module or connector preventing data transmission
5%
Normal code for production vehicles not equipped with experimental features
Diagnostic Steps
1
Step 1: Verify vehicle production date and determine if experimental features should be present on this vehicle
2
Step 2: Check module software versions and compare to latest manufacturer releases and TSBs
3
Step 3: Monitor SCP bus traffic to determine if experimental messages are present but invalid, or completely absent
4
Step 4: Test basic SCP bus communication and wiring integrity if other U-codes are also present
5
Step 5: Reprogram or update affected modules if outdated calibrations are confirmed, or clear code if it's expected on production vehicles
Estimated Repair Cost
$100 - $400
Parts + labor, varies by vehicle and location
This code indicates missing or corrupt data for experimental diagnostic parameter #2 on the J1850 SCP bus. Experimental codes typically relate to development features, manufacturer testing functions, or pre-production vehicle calibrations.
The most common cause of U1094 (SCP (J1850) Invalid or Missing Data for Experimental #2) is: Module software version mismatch or outdated calibration
Typical repair costs for U1094 range from $100 to $400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Generally no safety impact as experimental features are not part of normal vehicle operation. Vehicle should function normally.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1094 to identify the root cause.
