2023 Honda CR-V Hybrid ICM Software Update P060A

American Honda has announced a Product Update for certain 2023 CR-V Hybrid vehicles to address specific issues related to the Integrated Control Module (ICM). This update, detailed in Service Bulletin 23-017, aims to resolve problems that can lead to the Malfunction Indicator Lamp (MIL) illuminating and the active grill shutter failing to close properly when the vehicle is turned off. Owners experiencing a Honda CR-V ICM failure should be aware of this important service action.

The core of the problem is a software programming error within the ICM. This error can cause miscommunication between the main and sub CPU systems, leading the main CPU to incorrectly identify an ICM failure. This particular Honda CR-V ICM failure can trigger the MIL and prevent the active grill shutter from functioning as intended.

Symptoms of the ICM Software Issue

Owners of affected 2023 Honda CR-V Hybrid vehicles may notice one or both of the following symptoms:

• Illumination of the MIL: The Malfunction Indicator Lamp, often referred to as the "Check Engine" light, will turn on in the instrument cluster. This indicates a detected issue with the vehicle's powertrain or emissions system.
• Active grill shutter prevents closing: The active grill shutter, designed to improve aerodynamics and engine warm-up, may not close when the vehicle is turned off. This can impact fuel efficiency and engine performance.

Fault Codes / DTCs

The software programming error can lead to the detection of a specific diagnostic trouble code (DTC):

This update, detailed in Service Bulletin 23-017, aims to resolve problems that can lead to the Malfunction Indicator Lamp (MIL) illuminating and the active grill shutter failing to close properly when the vehicle is turned off. Owners experiencing a Honda CR-V ICM failure should be aware of this important service action.\n\nThe core of the problem is a software programming error within the ICM. This error can cause miscommunication between the main and sub CPU systems, leading the main CPU to incorrectly identify an ICM failure. This particular Honda CR-V ICM failure can trigger the MIL and prevent the active grill shutter from functioning as intended.\n\n## Symptoms of the ICM Software Issue\n\nOwners of affected 2023 Honda CR-V Hybrid vehicles may notice one or both of the following symptoms:\n\n* Illumination of the MIL: The Malfunction Indicator Lamp, often referred to as the "Check Engine" light, will turn on in the instrument cluster. This indicates a detected issue with the vehicle's powertrain or emissions system.\n* Active grill shutter prevents closing: The active grill shutter, designed to improve aerodynamics and engine warm-up, may not close when the vehicle is turned off. This can impact fuel efficiency and engine performance.\n\n## Fault Codes / DTCs\n\nThe software programming error can lead to the detection of a specific diagnostic trouble code (DTC):\n\n| Code | Description | Module |\n|---|---|---|\n| P060A | Internal Control Module Processor Performance | ICM (Integrated Control Module) |\n\n## Diagnosis and Trigger Conditions\n\nThe root cause of this issue is a software programming error that leads to miscommunication between the main and sub CPU systems within the Integrated Control Module. When this miscommunication occurs, the main CPU incorrectly determines that an ICM failure has taken place. This condition directly prevents the active grill shutter from operating correctly and causes the MIL to illuminate, signaling the presence of DTC P060A. This Honda CR-V ICM failure is a software-related problem, not a hardware defect.\n\n## Repair Procedure Summary\n\nThe resolution for this Honda CR-V ICM failure involves updating the software for the Integrated Control Module (ICM). This is a straightforward software flash procedure performed by a Honda dealership technician. According to Service Bulletin 23-017, the necessary software is available for this product update. No physical parts need to be replaced, and no special tools are required for this campaign.

Important Warnings for Owners and Dealers\n

• Dealer Responsibility: American Honda explicitly states that all affected 2023 CR-V Hybrid vehicles must be updated prior to sale to ensure customer confidence and satisfaction. Dealers are instructed to refer to their eResponsibility report or perform an iN VIN status inquiry to determine which units in their inventory are affected.\n* Customer Notification: American Honda expects to begin notifying customers by early April 2023. Owners should be aware that a notification letter will be sent out around this time.\n

Owner Action\n\nIf you own a 2023 Honda CR-V Hybrid and are experiencing the MIL illuminating or issues with your active grill shutter, or if you simply want to ensure your vehicle is updated, contact your authorized Honda dealership. Provide them with your vehicle's VIN so they can check its eligibility for this product update. Since this is a product update to correct a manufacturing software error, the repair will be performed free of charge under warranty.
