When repairing the JACB ASSY, note the following:
On part of the initial-lot JACB ASSY, the DCN1186-A (470 ohms, Part description
No. 471) is mounted as the resistors (R8820–8823, 8839–8844, 8855, and 8856).
In such a case, mount a new DCN1186-A during replacement.
This applies only to the initial-lot products for the destinations SYXJ8 and FLXJ.
For products for other destinations, replace with the DCN1185-A (330 ohms, Part
description No. 331), as described in the circuit diagram.
