SYMPTOM
Under certain circumstances when reversing near a chain-link fence or highly reflective surfaces, a parking and back-up
sensor system abnormal message may be displayed in the multi-information display (MID).
POSSIBLE CAUSE
When the back-up sensors detect a large number of reflected waves, the increased processing load on the sensor may
cause a memory processing overload.
CORRECTIVE ACTION
Clear any DTCs and update the parking and back-up sensor system software with the latest version.

SOFTWARE UPDATE PROCEDURE
NOTE:
•
•

•
•
•
•
•
•

Make sure the 12-volt battery is fully charged before starting an update.
Connect the Midtronics GR8-110P AST in Power Supply Mode, or the Midtronics DCA8-8000 Dynamic Diagnostic
Charging System in Reflash Mode, or the Associated Equipment Corporation ESS 6100 100A Smart Charger in Power
Supply Mode | DIAG+, directly to the vehicle’s 12-volt battery. Leave it connected during the entire procedure to
maintain a steady voltage.
Do not use a lithium-ion jump pack to supply power due to the pulses of high amperage that do not provide consistent
power to the battery during reprogramming.
If the vehicle’s 12-volt battery drops below 10 volts during the update, the programming status bar may not present
accurately, or the Honda ECU Reprogramming application may display an error message.
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.

1. Do an ALL DTC Check. Note any DTCs and then do an ALL DTC Clear.
2. Update the Parking Sensor software, see service bulletin 22-100, Updating Control Units/Modules with the Honda ECU
Reprogramming Application.
3. Do an ALL DTC Check and clear any codes that may have set during the update.
