DESCRIPTION
The main body ECU (multiplex network body ECU) receives remote control signals from the driver door key cylinder or wireless transmitter. Then, the main body ECU (multiplex network body ECU) sends the remote control signals to the sliding roof ECU (sliding roof drive gear sub-assembly) via LIN communication. The sliding roof ECU (sliding roof drive gear sub-assembly) receives those signals and activates the sliding roof motor.

2. |
CHECK SLIDING ROOF OPERATION |
(a) Check the sliding roof operation (See page ).
OK:
Sliding roof operation operates normally.
NG |
GO TO OTHER PROBLEM (Sliding Roof does not Move by Operating Sliding Roof Control) |
|
3. |
REPLACE SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY) |
(a) Replace the sliding roof ECU (sliding roof drive gear sub-assembly) (See page ).
|
4. |
INITIALIZE SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY) |
(a) Initialize the sliding roof ECU (sliding roof drive gear sub-assembly) (See page ).
|
5. |
CHECK REMOTE CONTROL FUNCTION |
(a) Check the key-linked and wireless transmitter-linked function (See page ).
OK:
The key-linked and wireless transmitter-linked function operates normally.
OK |
END (SLIDING ROOF ECU WAS DEFECTIVE) |
NG |
REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) |
Engine Coolant Temperature Receiver Gauge Malfunction
DESCRIPTION
In this circuit, the meter CPU receives engine coolant temperature signals from
the ECM using the CAN communication system (CAN V1 Bus). The meter CPU displays
engine coolant temperature that is calculated based on the data received from the
ECM.

Front Left Seat Heat Sensor Circuit (B14C1)
DESCRIPTION
Output to the front seat cushion heater assembly LH temperature sensor stops
if one of the following occurs: 1) the temperature sensor is open or shorted; or
2) the temperature sensor is damaged and its output value does not change.

Diameter of the Tire is not Uniform (C1337)
DESCRIPTION
The skid control ECU (brake actuator assembly) measures the speed of each wheel
by receiving signals from the speed sensors. These signals are used for recognizing
whether all 4 wheels are operating properly. Therefore, all wheel signals must indicate
the same speed.
