HONDA:

2020 Accord Hybrid, CR-V Hybrid; 2020-21 Insight

AFFECTED VEHICLES

BACKGROUND

Due to programming issues in the Power Control Unit (PCU), the DC-DC converter unit may generate excessive voltage, triggering the failsafe mode in the power supply control program. In this condition, the DC-DC converter unit is unable to supply power to the 12V battery, which may result in the illumination of the 12V battery warning light and a warning message to be displayed. If the vehicle continues to be driven in this condition, it may decrease driver assistance and could eventually stop running.

CUSTOMER NOTIFICATION

Owners of affected vehicles will be sent a notification of this campaign.

Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

Some vehicles affected by this campaign may be in your new or used vehicle inventory.

Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the customer or anyone else harmed as a result of such failure. Before selling a vehicle in inventory, always check if it is affected by a safety recall by conducting a VIN status inquiry.

REPAIR PROCEDURE

NOTE:

Make sure the 12-volt battery is fully charged before starting an update.
Connect a fully charged jumper battery to the vehicle, and leave it connected during the entire procedure to maintain steady voltage.
Do not use the GR8 because the vehicle requires a steady electrical current.
Control module failure caused by the improper completion of a software update (early key cycle, low battery voltage, disconnected DLC cable, etc.) is not covered by warranty.
If an error occurs during the update or the i-HDS freezes, do not disconnect the battery or turn the ignition to OFF. Reboot the i-HDS, and start over.
To prevent control unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, door locks, etc.) during the update.
Warranty reimbursement for technician labor is not allowed for routine checking/installation of any available software update.

NOTE: This update will not require entering a service bulletin number.

Update the PCU software using the J2534 Rewrite software with the DST-i. Refer to service bulletin 01-023, Updating Control Units/Modules.
Do the CKP pattern learn procedure. Refer to the service information.
