PRECAUTION
1. PRECAUTIONS WHEN CHECKING FOR DTCS
(a) When the cable is disconnected from the negative (-) battery terminal, the DTCs stored in the steering lock ECU (steering lock actuator or UPR bracket assembly) are cleared. Be sure to record any output DTCs immediately.
(b) Normally, with the engine switch off, even if the Techstream is connected to the vehicle, the information stored in the smart key system related ECUs (the certification ECU (smart key ECU assembly), main body ECU, etc.) cannot be read. However, smart key system DTCs and Data List information can be confirmed even if the engine switch is off using either of the two methods below:
2. PRECAUTIONS WHEN REPLACING STEERING LOCK ECU (STEERING LOCK ACTUATOR OR UPR BRACKET ASSEMBLY)
(a) If the steering lock ECU (steering lock actuator or UPR bracket assembly) is replaced, be sure to confirm that the steering is unlocked by turning the steering wheel to the left and right before starting the engine. If the steering is locked for any reason, open and close a door with the engine switch off, and then unlock the steering lock by pressing the engine switch. This prevents the engine from starting while the steering is locked.
3. PRECAUTION FOR REGISTRATION
(a) If replacing any of the following parts, refer to the registration procedures
(See page ).
(1) Certification ECU (Smart key ECU assembly)
(2) Steering lock ECU (steering lock actuator or UPR bracket assembly)
(3) Main body ECU (Multiplex network body ECU)
(4) Electrical key transmitter sub-assembly
(5) ECM
4. PRECAUTIONS FOR STEERING LOCK / UNLOCK FUNCTION
(a) After turning the engine switch off and opening and closing any of the doors, the steering wheel will be locked due to the steering lock function. Operating the engine switch again automatically cancels the steering lock function.
(b) To prevent the steering lock motor from overheating, the motor operation may be suspended if the steering is locked and unlocked repeatedly in a short period of time. In this case, refrain from operating the engine switch. After about 10 seconds, the steering lock motor will resume functioning.

Fuel Receiver Gauge Malfunction
DESCRIPTION
The meter CPU uses the fuel sender gauge assembly to determine the level of the
fuel in the fuel tank. The resistance of the fuel sender gauge will vary between
approximately 13.5 Ω with the float at the full position, and 414.5 Ω with the float
at the empty position. The meter ...
