Invalid Data Received From Speech Recognition Module

Where it lives

For U0564, start at the module the description names.

Check these first

• A fault inside the speech recognition module itself
• A loose, corroded, or water damaged connector at the speech recognition module
• An open or short in the speech recognition module wiring to the module that receives its data
• A lost power or ground feed to the speech recognition module

What to do next

1. Scan all modules and record the stored and pending network codes
2. Inspect the speech recognition module connector pins for corrosion, water, and looseness
3. Test the speech recognition module power and ground feeds under load
4. Repair or replace the speech recognition module if the circuit, power, and bus tests pass
5. Clear the code and retest to confirm the speech recognition module fault is gone
