6. CHECK MEMORY CALL FUNCTION Check automatic memory call function With a transmitter key recognition code registered: Perform a wireless door unlock operation and check that opening the driver side door causes the following: The buzzer sounds for 0.1 seconds. The front seat and outer mirror surface position automatically move to the stored positions. HINT: The registered transmitter key recognition code is recalled automatically. If the automatic memory call function is not operated, the buzzer will not sound. With the power switch off and the driver side door closed, press and hold the M1, M2 or M3 switch while carrying the transmitter key. The main body ECU (multiplex network body ECU) will enter transmitter key recognition code registration mode to allow a key to be linked to mirror surface memory position. HINT: If the memory switch is released before entering registration mode, the memory switch will not enter registration mode.

DIAGNOSIS SYSTEM

1. DESCRIPTION Data of the system can be read from the Data Link Connector 3 (DLC3) of the vehicle. Therefore, when the system seems to be malfunctioning, use the Techstream to check for a malfunction and repair it.
2. CHECK DLC3 Check the DLC3. Refer to «GENERAL INFORMATION»(ref-568589-S28103458762013072300000) .

DATA LIST / ACTIVE TEST

1. USING TECHSTREAM Connect the Techstream to the DLC3. Monitor the ECU data by following the prompts on the Techstream screen. HINT: The Techstream has a "Snapshot" function which records the monitored data. Refer to the Techstream operator's manual for further details.
2. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time. Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on.
