Troubleshooting

Code Description

Code 4C! indicates a communication problem between the Electronic

Control Unit (ECU) and the Operator Control Panel (OCP). Code 4C! will

only be observable on a diagnostic tool, it will not show on the Operator

Control Panel. Instead, the Operator Control Panel may be blank

(indicating a power problem) or may display only the logo (indicating a

signal problem).

All of the troubleshooting steps for code 4C! involve checking the

condition of Electronic Control Unit and the Operator Control Panel

circuits. If no circuit problems are found, Code 4C! indicates either a

faulty Operator Control Panel or a faulty Electronic Control Unit.

See “Troubleshooting Tips” on page 20 for general guidelines on system

diagnostics.
