Trouble typeC8101: Before reading pressure welding alienation mechanism trouble
RankB
Trouble detection condition-During a pressure motion being performed, the before read sensor (PS6) output does not change from H to L.
-During a retraction motion being performed, the before read sensor (PS6) output does not change from L to H.
Trouble isolationDF
Relevant electrical parts-Reading roller pressure/retraction motor (M6)
-Before read sensor (PS6)
-DF control board (DFCB)

 Procedure

  1. Check the connector between M6-relay CN118-DFCB CN4 for proper connection and correct as necessary.
  2. Check the connector of M6 for proper drive coupling and correct as necessary.
  3. Check the connector between PS6-relay CN120-DFCB CN11 for proper connection and correct as necessary.
  4. PS6 I/O check, sensor check
    • Control signal: DFCB CN11-2 (ON)
    • Location of electrical component: DF 1-C
  5. M6 load check
    • Check code: 60
    • Multi code: 81, 82
    • Control signal: DFCB CN4-1 to 2
    • Location of electrical component: DF 10-C
  6. Replace M6. (Part# A782R70100)
  7. DFCB ICP9 conduction check.
  8. Replace DFCB. (Part# A782H0010A)
