U2160 – SCP (J1850) Invalid Data from IC
The ODBII code U2160 SCP (J1850) Invalid Data from IC indicates that the vehicle’s communication network has received invalid data from the Instrument Cluster (IC), which may affect the proper functioning of various systems.
The severity of ODBII code U2160 SCP (J1850) Invalid Data from IC is moderate.
Common Causes For: U2159 Lost Communication with Instrument Cluster.
- Faulty Instrument Cluster
- Poor or corroded connections in the wiring harness
- Short circuit in the communication lines
- Faulty or damaged sensors
- Malfunctioning Body Control Module (BCM)
- Issues with the vehicle’s data bus
- Software glitches or programming errors
- Low battery voltage or power supply issues

Common Troubleshooting Steps
The OBD-II code U2160 indicates that there is an issue with the communication on the SCP (Serial Communication Protocol) bus, specifically related to invalid data from the Instrument Cluster (IC). Here are some common troubleshooting steps to diagnose and resolve this issue:
- Check for Additional Codes: Use an OBD-II scanner to check for any other trouble codes that may be present. This can provide more context about the issue.
- Inspect Wiring and Connectors: **Visual Inspection: Check the wiring and connectors related to the instrument cluster and the SCP bus for any signs of damage, corrosion, or loose connections.
- **Repair or Replace: Repair any damaged wires or connectors as necessary.
- Check Battery Voltage: Ensure that the vehicle’s battery is fully charged and that the voltage is within the normal range (typically 12.4 to 12.6 volts when the engine is off).
- Inspect the Instrument Cluster: **Functionality Check: Verify that the instrument cluster is functioning properly. Look for any unusual behavior, such as gauges not working or warning lights staying on.
- **Reboot/Reset: Sometimes, disconnecting the battery for a few minutes can reset the instrument cluster and clear temporary glitches.
- Test the SCP Bus: Use a multimeter or an oscilloscope to check the SCP bus for proper voltage levels and signal integrity. Look for any irregularities in the communication signals.
- Check for Short Circuits: Inspect the SCP bus for any short circuits to ground or to other circuits that could be causing interference.
- Scan for Software Updates: Check if there are any software updates available for the vehicle’s ECU or instrument cluster. Sometimes, manufacturers release updates to fix known issues.
- Replace Faulty Components: If the instrument cluster is determined to be faulty after testing, consider replacing it. If other components on the SCP bus are suspected, they may also need to be tested and replaced.
- Consult Technical Service Bulletins (TSBs): Look for any TSBs related to the U2160 code or the specific vehicle model. Manufacturers may have documented common issues and solutions.
- Professional Diagnosis: If the issue persists after performing the above steps, consider seeking help from a professional mechanic or dealership with experience in diagnosing communication issues.Conclusion Troubleshooting OBD-II code U2160 requires a systematic approach to identify and resolve communication issues on the SCP bus. By following these steps, you can narrow down the potential causes and take appropriate action to fix the problem.
