1. FAIL-SAFE
This function minimizes the loss of the ECT functions when any malfunction occurs in a sensor or solenoid.
(a) ATF (Automatic Transmission Fluid) temperature sensor: When the ATF temperature sensor has a malfunction, 5th upshift is prohibited.
(b) Counter gear speed sensor NC (Speed sensor NC): When the counter gear speed sensor has a malfunction, 5th upshift is prohibited.
(c) Shift solenoid valve DSL: When the solenoid valve DSL has a malfunction, the current to the solenoid valve is stopped.
This stops lock-up control, then fuel economy decreases.
(d) Shift solenoid valve SL1, SL2, SL3 and S4: Fail safe function: If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift solenoid "ON" and "OFF" in order to shift into the gear positions shown in the table below.
Manual shifting as shown in the following table must be done (In case of a short circuit, the ECM stops sending the current to the short circuited solenoid).
Even if starting the engine in the fail-safe mode, the gear position remains in the same position.
HINT: FL: Flex Lock-up
Initialization
HINT:
The seatback position is initialized at the factory before
shipment, so initialization is not normally required.
There is an initialization function for cases when
reinitialization is required.
Before performing initialization procedure and initialization

On-vehicle inspection
1. INSPECT REAR AXLE HUB BEARING BACKLASH
(a) Using a dial gauge, check for backlash near the
center of the axle hub.
Maximum:
0.05 mm (0.0020 in.)
If backlash exceeds the maximum, replace the axle
hub assembly.
NOTICE:
Ensure that the dial gauge is set at right angles
to the measuremen ...
