What Does U1017 Mean?
This code represents another missing module ID on the SCP network. The pattern of U1013-U1017 being present together strongly suggests a systemic network bus failure rather than multiple simultaneous module failures.
Common Causes
40%
Complete SCP bus circuit failure due to wire damage or connector failure
25%
Failed four-wheel drive module or transfer case control module
18%
Multiple modules unpowered due to main power distribution failure
12%
Ground distribution failure affecting multiple module ground circuits
5%
Lightning strike or electrical surge damage to multiple modules
Diagnostic Steps
1
Step 1: Check all main power distribution fuses and relays that supply control modules
2
Step 2: Verify main ground connections are clean, tight, and have less than 0.1 ohm resistance
3
Step 3: Test SCP bus continuity from each module location to verify bus integrity throughout vehicle
4
Step 4: Use scan tool network test function to monitor real-time module communication status
5
Step 5: If bus is physically intact, consider central gateway or hub module failure disabling network
Estimated Repair Cost
$200 - $1,600
Parts + labor, varies by vehicle and location
This code represents another missing module ID on the SCP network. The pattern of U1013-U1017 being present together strongly suggests a systemic network bus failure rather than multiple simultaneous module failures.
The most common cause of U1017 (SCP (J1850) Invalid or Missing Data for Primary Id) is: Complete SCP bus circuit failure due to wire damage or connector failure
Typical repair costs for U1017 range from $200 to $1,600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Multiple vehicle systems may be non-functional creating unpredictable vehicle behavior. Traction control, ABS, stability control, and other safety systems may not operate.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1017 to identify the root cause.
