| Trouble type | C8101: Before reading pressure welding alienation mechanism trouble |
| Rank | B |
| 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 isolation | DF |
| Relevant electrical parts | -Reading roller pressure/retraction motor (M6) -Before read sensor (PS6) -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 PS6-relay CN120-DFCB CN11 for proper connection and correct as necessary.
- PS6 I/O check, sensor check
- Control signal: DFCB CN11-2 (ON)
- Location of electrical component: DF 1-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)
