What Does U1117 Mean?
Additional module reporting inability to receive electrical energy management data on the network. When stored with U1116, indicates multiple modules affected by energy management communication failure.
Common Causes
35%
SCP network bus fault preventing broadcast of energy management data
30%
Failed smart battery sensor not providing data to network
20%
Body control module or smart junction box communication failure
10%
Module software out of date lacking energy management protocol
5%
Poor ground connection at battery negative cable
Diagnostic Steps
1
Step 1: Use scan tool to identify which modules are successfully receiving energy management data
2
Step 2: Test battery current sensor output signal and verify proper voltage at sensor connector
3
Step 3: Check network bus integrity between battery sensor, junction box, and affected modules
4
Step 4: Perform module health check and verify all control modules are communicating on network
5
Step 5: Update all module software to latest versions and retest for code persistence
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
Additional module reporting inability to receive electrical energy management data on the network. When stored with U1116, indicates multiple modules affected by energy management communication failure.
The most common cause of U1117 (SCP (J1850) Invalid or Missing Data for Electrical Energy Management) is: SCP network bus fault preventing broadcast of energy management data
Typical repair costs for U1117 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Primarily affects battery management and charging optimization. Vehicle remains safe to drive but may experience reduced battery life or electrical system efficiency.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U1117 to identify the root cause.
