Trouble type | C8101: Before reading pressure welding alienation mechanism trouble |
Rank | B |
Trouble detection condition | • During a pressure motion being performed, the read roller home sensor (PS8) output does not change from H to L. • During a retraction motion being performed, the read roller home sensor (PS8) output does not change from L to H. |
Trouble isolation | DF |
Relevant electrical parts | • Reading roller pressure/retraction motor (M6) • Read roller home sensor (PS8) • DF control board (DFCB) |
Procedure
- Check the connector between M6-relay CN118-DFCB CN4 for proper connection and correct as necessary.
- Check the connector of M6 for proper drive coupling and correct as necessary.
- Check the connector between PS8-relay CN119-DFCB CN11 for proper connection and correct as necessary.
- PS8 I/O check, sensor check
- Control signal: DFCB CN11-9 (ON)
- Location of electrical component: DF 2-C
- M6 load check
- Check code: 60
- Multi code: 81, 82
- Control signal: DFCB CN4-1 to 2
- Location of electrical component: DF 10-C
- Replace M6. (Part# A782R70100)
- DFCB ICP9 conduction check.
- Replace DFCB. (Part# A782H0010A)
