Toyota Australia Initiates Customer Service Exercise For Parking Support Brake System Reprogramming

Toyota Australia has today announced that it will initiate a Customer Service Exercise (CSE) for Parking Support Brake (PKSB) System reprogramming on a range of Toyota CH-R Hybrid vehicles produced between 2 May 2023 and 30 May 2024. There are approximately 2348 vehicles involved in the Australian market.

When subject vehicles are towing (e.g. a trailer or bicycle rack), the Parking Support Brake (PKSB) system operates unintentionally when reverse gear is selected. The PKSB software defaults to the ON state when reverse is selected. This will result in the PKSB system activating the vehicle brakes when the shift position is moved into reverse. This is caused by PKSB software logic.

For the involved vehicles, Toyota Dealers will fit a correction sticker to the vehicle Owner’s Manual and perform a software update to the Clearance Warning ECU on involved vehicles.

For all involved vehicles, the reprogramming will take approximately 60 minutes. However, depending on the Dealer's work schedule, owners may be required to make the vehicle available for a longer period of time.

Toyota Australia will contact all owners of involved vehicles to provide details of this CSE campaign. Owners are asked to keep their contact details up to date with Toyota so future communications can be received.

Owners with additional questions or concerns are asked to please contact their local/preferred Toyota Dealer in the first instance or the Toyota Campaign Helpline on 1800 987 366 (Mon-Fri 8.00am-6.00pm AEST). Please quote your 17-digit Vehicle Identification Number (VIN).
