SSU 000162.09 – Incorrect CAN BUS Message, Transmission Type from EPC or TCU

SSU 000162.09 (SSU 162.09)

Code: 000162.09

Shortcode: 162.09


This diagnostic trouble code (DTC), SSU 000162.09, is generated when the information on transmission type (entry in address SSU 036) is not recognized on the CAN BUS after four attempts. This indicates a communication issue with the CAN BUS, specifically between the Electronic Power Control (EPC) or Transmission Control Unit (TCU) and the Body Control Unit (BCU).


When this error is detected, the equipment may not correctly identify the transmission type, leading to potential issues with vehicle operation and diagnostics.


Verify CAN BUS Communication:

  • Inspect the CAN BUS wiring and connectors for any signs of damage, loose connections, or corrosion.
  • Use diagnostic tools to check for continuity and proper voltage levels in the CAN BUS lines.

Check Transmission Type Entry:

  • Ensure that the transmission type information at address SSU 036 is correctly entered and recognized by the system.
  • Verify that the EPC or TCU is correctly configured and functioning.

Update Software:

  • Ensure that the EPC, TCU, and BCU software are up-to-date. Update the software to include the latest diagnostic trouble codes and communication protocols.

Replace Faulty Components:

  • If any components within the CAN BUS network are found to be defective, replace them with new, genuine parts.

Consult Technical Support:

  • If the error persists after performing the above steps, consult technical support or the manufacturer for further assistance in identifying and resolving the issue.


  • Regular maintenance and inspection of the CAN BUS wiring and connected components can help prevent this issue.
  • This code may sometimes be triggered by intermittent faults in the CAN BUS communication, so monitoring the system for any recurrence is crucial.
