DESCRIPTION
When the wireless operation can be used to lock and unlock the doors, communication between the electrical key and TPMS receiver assembly and certification ECU (smart key ECU assembly) is normal. If the entry lock and unlock functions do not operate, the entry cancel function may be set through the customize function, there may be communication problems between the electrical key transmitter sub-assembly and vehicle, or there may be wave interference.

PROCEDURE
1. |
CHECK POWER DOOR LOCK CONTROL SYSTEM |
(a) When the door control switch on the power window regulator master switch
assembly is operated, check that the doors unlock and lock according to the switch
operation (See page ).
OK:
Door locks operate normally.

CHECK WAVE ENVIRONMENT |
(a) Move the electrical key transmitter sub-assembly as described below and perform the operation inspection.
HINT:
(1) Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly LH and perform a driver door entry lock and unlock operation check. HINT: Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the rear bumper. Text in Illustration

3. |
CHECK KEY DIAGNOSTIC MODE |
(a) Check the following antennas in key diagnostic mode (See page
).
(b) Select either channel 1 or channel 2 and perform key diagnostic mode inspection for each channel.
(1) Check the electrical key antenna (for driver door): When the electrical key transmitter sub-assembly is brought within 0.7 to 1 m (2.30 to 3.28 ft.) of the front door outside handle assembly LH, check that the wireless buzzer sounds. HINT:
OK: Wireless buzzer sounds. Text in Illustration

Low Power Supply Voltage Malfunction (C1241)
DESCRIPTION
If there is a problem with the skid control ECU (master cylinder solenoid) power
supply circuit, the skid control ECU outputs the DTC and prohibits operation under
the fail-safe function.
If the voltage supplied to terminal IG1 is not within the DTC detection threshold
due to mal ...

1. DESCRIPTION
The main body ECU (multiplex network body ECU) and certification ECU (smart key
ECU assembly) control the LIN communication system. LIN communication system data
and Diagnostic Trouble Codes (DTCs) can be read through the Data Link Connector
3 (DLC3).

DESCRIPTION
In Test Mode (signal check), a malfunction in the speed sensor that cannot be
detected when the vehicle is stopped can be detected while driving.
Sensor check mode can be entered by connecting terminals TS and CG of the DLC3
and turning the ignition switch from off to ON.
