1. 1

   Confirm if the operator is experiencing actual CSM sequence failures, as this code is a normal informational event

2. 2

   Check for subsequent operational codes, such as Id78A2h, which indicates the tractor speed is too low (under 1.5 km/h) to start the sequence

1. 1

   Check CAN bus wiring

   Check the CLAAS vehicle CAN bus network wiring and connectors (if the EXT module is failing to communicate entirely, e.g., code Id7882h).

2. 2

   Verify module power and ground

   Verify power, ground, and continuity to the EXT (A62) module.
