With the power switch off and the retractable outer mirror switch AUTO, when the doors are locked through the entry, wireless or key-linked function, check that the outer mirror actuators move from the driving position to the retracted position, and then stop in the retracted position. When the power switch is on (ACC) and then turned off while the retractable outer mirror switch is AUTO, check that both outer mirror actuators automatically move from the driving position to the retracted position. When the power switch is off and then turned on (ACC) while the retractable outer mirror switch is AUTO, check that both outer mirror actuators automatically move from the retracted position to the driving position.
4. CHECK MEMORY AND MIRROR RESTORING OPERATION TEXT IN ILLUSTRATION *1 SET Switch *2 M1 Switch *3 M2 Switch *4 M3 Switch HINT: If the M1 switch, M2 switch and M3 switch are simultaneously pressed while the SET switch is pressed and held, the seat position will not be stored. Turn the power switch on (IG) and move the shift lever to P. Check the M1 switch. Using the outer mirror switch, turn the mirror surface to the full left position. TEXT IN ILLUSTRATION *a Turn to Left Fully Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized when the M1 switch is pressed within 3 seconds after the SET switch is pressed. NOTE: The mirror surface position will also be stored when the M1 switch is pressed after first pressing and holding the SET switch. The mirror surface position will not be stored when the SET switch and M1 switch are pressed simultaneously. The mirror surface position will not be stored when 2 or more of the memory switches are pressed simultaneously (for example, M1 and M2) after first pressing the SET switch. Using the outer mirror switch, turn the mirror surface to the full right position. Press the M1 switch.

DATA LIST / ACTIVE TEST [03/2012 - ]

1. 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. NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not. Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on.
