What Does U1116 Mean?
The module cannot receive electrical energy management data over the SCP network. This affects systems that monitor and control battery load to prevent excessive discharge or electrical system overload.
Common Causes
30%
Failed battery monitoring sensor or smart junction box
25%
Network communication fault preventing data broadcast
25%
Defective PCM unable to process or transmit energy management data
15%
Corroded or damaged wiring at battery current sensor
5%
Software calibration issue in control modules
Diagnostic Steps
1
Step 1: Verify battery current sensor is properly connected and showing readings on scan tool
2
Step 2: Check for proper voltage and ground at battery monitoring sensor connector
3
Step 3: Monitor energy management PIDs on scan tool to see which modules have valid data
4
Step 4: Inspect smart junction box or battery sensor harness for water intrusion or corrosion
5
Step 5: Verify PCM and body control module software is up to date with latest calibrations
Estimated Repair Cost
$150 - $700
Parts + labor, varies by vehicle and location
The module cannot receive electrical energy management data over the SCP network. This affects systems that monitor and control battery load to prevent excessive discharge or electrical system overload.
The most common cause of U1116 (SCP (J1850) Invalid or Missing Data for Electrical Energy Management) is: Failed battery monitoring sensor or smart junction box
Typical repair costs for U1116 range from $150 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May result in premature battery failure or unexpected battery discharge. Vehicle electrical systems should function normally but battery life monitoring will be inaccurate.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1116 to identify the root cause.
