Toyota Avalon (XX50) 2019-2022 Service & Repair Manual: Operation Check

OPERATION CHECK

CHECK ELECTRICAL REMOTE CONTROL MIRROR FUNCTION

(a) Turn the engine switch on (IG).

(b) With the mirror select switch L switch on, check that the outer rear view mirror assembly LH surface moves up, down, left and right normally.

(c) With the mirror select switch R switch on, check that the outer rear view mirror assembly RH surface moves up, down, left and right normally.

CHECK MEMORY AND REACTIVATION FUNCTION

HINT:

The SET, M1 and M2 seat memory switches are shown in the illustration.

(a) Turn the engine switch on (IG) and move the shift lever to P.

(b) Check the M1 switch.

(1) Using the outer mirror switch assembly, turn the mirror surface to the fully left position.

(2) Check that the buzzer sounds for 0.5 seconds and the seat and mirror surface position is memorized when the M1 switch is pressed within 3 seconds of the SET switch being pressed.

NOTICE:

• The mirror surface position will also be memorized when the M1 switch is pressed after first pressing and holding the SET switch.
• The mirror surface position will not be memorized when the SET switch and M1 switch are pressed simultaneously.
• The mirror surface position will not be memorized when 2 or more of the memory switches are pressed simultaneously (for example, M1 and M2) after first pressing the SET switch.

(3) Using the outer mirror switch assembly, turn the mirror surface to the fully right position.

(4) Press the M1 switch.

(5) Check that the buzzer sounds for 0.1 seconds and the mirror surface automatically moves to the memorized fully left position.

(c) Check the M2 switch.

(1) Using the outer mirror switch assembly, turn the mirror surface to the fully right position.

(2) Check that the buzzer sounds for 0.5 seconds and the seat and mirror surface position is memorized when the M2 switch is pressed within 3 seconds of the SET switch being pressed.

NOTICE:

• The mirror surface position will also be memorized when the M2 switch is pressed after first pressing and holding the SET switch.
• The mirror surface position will not be memorized when the SET switch and M2 switch are pressed simultaneously.
• The mirror surface position will not be memorized when 2 or more of the memory switches are pressed simultaneously (for example, M1 and M2) after first pressing the SET switch.

(3) Using the outer mirror switch assembly, turn the mirror surface to the fully left position.

(4) Press the M2 switch.

(5) Check that the buzzer sounds for 0.1 seconds and the mirror surface automatically moves to the memorized fully right position.

CHECK MEMORY CALL FUNCTION

(a) Memory call function check

(1) With an electrical key transmitter sub-assembly recognition code registered, perform a wireless door unlock operation and check that opening the driver door causes the following:

• The buzzer sounds for 0.1 seconds.
• The driver seat and mirror surface positions automatically move to the memorized positions.

HINT:

• The registered electrical key transmitter sub-assembly recognition code is recalled automatically.
• If the memory call function is not operated, the buzzer will not sound.

(b) With the engine switch on (IG) and the driver door closed, press and hold the M1 or M2 switch while carrying the electrical key transmitter sub-assembly. The main body ECU (multiplex network body ECU) will enter electrical key transmitter sub-assembly recognition code registration mode to allow a key to be linked to mirror surface memory position.

HINT:

If the seat memory switch is released before entering registration mode, the main body ECU (multiplex network body ECU) will not enter registration mode.

(c) When the manual door lock switch is pressed, check that the buzzer sounds once (0.5 seconds).

(d) With the engine switch on (IG) and the driver door closed, press and hold the SET switch while carrying the electrical key transmitter sub-assembly. The main body ECU (multiplex network body ECU) will enter electrical key transmitter sub-assembly recognition code deletion mode.

HINT:

If the seat memory switch is released before entering deletion mode, the main body ECU (multiplex network body ECU) will not enter deletion mode.

(e) When the manual door lock switch is pressed, check that the buzzer sounds twice (0.1 seconds each time).

CHECK MEMORY CALL EMERGENCY STOP FUNCTION

(a) While a memory call function is operating, check that any one of the following actions will stop the memory call operation: 1) pressing the SET, M1 or M2 switch, 2) moving the shift lever to R, 3) moving the mirror surface manually, or 4) moving the mirror surface to the uppermost, lowermost, leftmost or rightmost position.

CHECK MIRROR HEATER FUNCTION

(a) Turn the engine switch on (IG).

(b) Check that pressing the mirror heater switch (rear window defogger switch) illuminates the indicator and warms the mirror surfaces.

(c) Check that after approximately 15 minutes, the indicator light turns off and the mirror heaters deactivate.

HINT:

There is a timer extension function which can operate the mirror heaters for up to an additional 45 minutes.

CHECK AUTOMATIC GLARE-RESISTANT EC MIRROR FUNCTION

(a) Check that the automatic glare-resistant EC mirror function of the outer rear view mirror assemblies operates when the automatic glare-resistant function of the inner rear view mirror assembly operates.
