Lost Communication With Accelerator Pedal Module

Where it lives

For U013C, the description names the module as the part involved.

Check these first

• A wiring or connector fault between the Accelerator Pedal Module and the network
• A failed Accelerator Pedal Module
• Corrosion or water in the module connector
• An incorrect module fitted that does not match the vehicle
• A software fault that drops the module offline

What to do next

1. Scan all modules for communication codes
2. Inspect the Accelerator Pedal Module connector for corrosion or water
3. Check the module power and ground feeds
4. Verify the module matches the vehicle specification
5. Replace the Accelerator Pedal Module if the bus and feeds test good
6. Clear the code and retest
