E197 2101 05 Title Communication error
Detection Although access to KONA3 (ASIC) in the Cassette Module
description Controller PCB from the DC Controller PCB (CPU) was
performed, no response was received and timeout occurred.
Remedy [Related parts]
- Harness between the DC Controller PCB (UN04/J190) and the
cassette unit drawer (DR03/J5904) on the host machine side
(Unit of replacement: OPTION CST. DRAWER ASSEMBLY)
- Harness between the cassette unit drawer (DR03/J5904)
on the host machine side and drawer (DR101/J5950) on the
cassette unit side
- Harness between the drawer (DR101/J5950) on the cassette
unit side and the Cassette Module Controller PCB (UN101/
J650) (Unit of replacement: DRAWER CABLE ASSEMBLY)
- Fuse in the DC Controller PCB (UN04/FU19) (Unit of
replacement: DC CONTROLLER PCB ASSEMBLY)
- Cassette Module Controller PCB (UN101/J650) (Unit of
replacement: CST. PEDESTAL CONT. PCB ASS'Y)
- DC Controller PCB (UN04) (Unit of replacement: DC
CONTROLLER PCB ASSEMBLY)
[Points to note at work] When checking the harness/cable or
connector, perform the following work.
1. Disconnect and then connect the connector to check that
there is no bent pin and cable disconnection.
2. Visually check that the harness is not caught or open circuit.

Remedy [Remedy] Perform the following in the order while checking
whether the error is cleared.
1. Turn OFF and then ON the main power, and check whether
the error is cleared.
2. Check the harness between the DC Controller PCB and the
cassette unit drawer on the host machine side.
3. Visually check if the cassette unit drawer on the host machine
side and the drawer on the cassette unit side are damaged or if
there is any bent pin. If so, replace the drawer.
4. Check the harness between the drawer on the cassette unit
side and the Cassette Module Controller PCB.
5. Measure the both ends of the fuse in the DC Controller PCB
using a tester.
a. If the measurement value is less than 1 ohm (conduction
state),
1. Replace the Cassette Module Controller PCB.
2. Replace the DC Controller PCB.
b. If the measurement value is 1 ohm or higher (non
conduction state), replace the DC Controller PCB.
[Reference] Before replacing the DC Controller PCB, back up
the service mode data (approx. 2 min) and restore the backup
data after the replacement so the data may be able to be
protected.
