Canon iRC5880N

Cause

When drawing out the Pkit as part of servicing work, you need to disconnect and then connect the connectors. When repeated, their internal pins can start to suffer from poor connection, resulting in wrong operation/detection.

Description

A break in the harness can occur when the harness is disconnected/connected about 30 times. The following is a list of harnesses that are subject to a break with descriptions of symptoms expected when a break occurs.
