Toyota 86 vehicle to be recalled
Aug 4, 2016 By Toyota Australia.
Toyota Australia has today announced that it will recall almost 15,000 Toyota 86 vehicles built between April 2012 and March 2015 due to a potential loss of power steering assist.
The recall impacts right-hand drive vehicles that are equipped with driver's knee airbags.
Due to an improper wire harness layout, there is a possibility that the electric power steering harness may interfere with the instrumental panel lower cover which contains the driver's knee airbag on Australian specification vehicles.
If this happens, there could be an electrical contact failure which may result in the loss of power steering assist. A warning light would then illuminate on the dashboard along with a short audible warning whilst manual steering would be maintained.
To rectify this condition, the power steering electronic control unit and wire harness will be replaced in all impacted vehicles.
Toyota Australia expects that parts will arrive at dealerships from late next month. A letter will then be sent by registered mail to all impacted owners to request that they make an appointment at their preferred Toyota dealer.
The repair work will take just over an hour and will be carried out free of charge
There have been 62 reports in Australia with no accidents or injuries reported as a result of this condition.

Toyota 86 Electric Power Steering (EPS) Assistance Q and A
Q1: What is the condition?
A1: The subject vehicles are equipped with electric power steering (EPS).
During normal driving operation, the EPS rotation angle sensor terminals may wear over time. This wear of the connector terminal plating accumulates in debris which may oxidise and become non-conductive.
Under this condition if the driver's knee contacts the knee airbag lower cover, the EPS wire harness routed behind the cover also moves significantly which allows the terminal to contact the debris resulting in electrical contact failure.
In this condition, the EPS ECU turns on the warning light and the steering assist is interrupted whilst manual steering is maintained.
The loss of power steering assist will increase the steering effort at low speeds which may increase the risk of an accident.
Q2: What is the function of the Electronic Power Steering?
A2: The electric power steering system generates torque to assist steering effort through operation of the motor and reduction gear installed on the steering column shaft.
The power steering electronic control unit (ECU) determines direction and the amount of assistance required in accordance with vehicle speed and signals from sensors built into the steering column assembly.
Q3: Which and how many vehicles are involved?
A3: There are 14,906 Toyota 86 vehicles involved in the Australian market.
