What Does U1007 Mean?
Similar to U1006, this code indicates the SCP network is not receiving valid primary identification data from a control module. Multiple U-codes often point to widespread network communication issues.
Common Causes
35%
Damaged SCP network wiring or short to ground/power
30%
Faulty body control module or gateway module
20%
Poor ground connections affecting multiple modules
15%
Module programming or software corruption
Diagnostic Steps
1
Step 1: Verify battery voltage is stable above 12V; perform charging system test to ensure alternator output is 13.5-14.5V
2
Step 2: Use scan tool network test function to identify all modules on SCP bus and note which are missing or intermittent
3
Step 3: Measure resistance between SCP+ and SCP- terminals at data link connector; should be approximately 50-70 ohms
4
Step 4: Check for aftermarket accessories or alarm systems that may have tapped into SCP network improperly
5
Step 5: Disconnect modules one at a time to isolate a potentially shorted module pulling down the bus
Estimated Repair Cost
$100 - $900
Parts + labor, varies by vehicle and location
Similar to U1006, this code indicates the SCP network is not receiving valid primary identification data from a control module. Multiple U-codes often point to widespread network communication issues.
The most common cause of U1007 (SCP (J1850) Invalid or Missing Data for Primary Id) is: Damaged SCP network wiring or short to ground/power
Typical repair costs for U1007 range from $100 to $900, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May cause instrument panel malfunctions, loss of warning indicators, or reduced accessory functionality. Monitor gauges and warning lights closely.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1007 to identify the root cause.
