Procedure<\/h2>\n\n\n\n
  1. Check the connector between M11-relay CN112-EXCB CN14EX for proper connection and correct as necessary.<\/li>
  2. Check the connector between the fusing unit-relay CN95, CN96-BASEB CN4E for proper connection and correct as necessary.<\/li>
  3. Check the connector between EXCB CN2EX-BASEB CN12E for proper connection and correct as necessary.<\/li>
  4. Check CPUB for proper installation and correct as necessary.<\/li>
  5. PS38 I\/O check, sensor check
