• Code: E193-0000-05
• Description: Communication error
• Causes: NACK was received twice at communication retry of image ASIC.
• Remedy: [Related parts] R1.00 - Harness between the DC Controller PCB (UN04/J112) and the Main Controller PCB (UN81/ J4511) - Main Controller PCB (UN81) - DC Controller PCB (UN04) [Remedy] Check/replace the related harness/cable, connector and parts.
