Wireless Transmitter Memory Function does not Operate
MIRROR (EXT): POWER MIRROR CONTROL SYSTEM (w/ Memory): Wireless Transmitter Memory Function does not Operate
- Wireless Transmitter Memory Function does not Operate
DESCRIPTION
The key ID can be registered to be linked with each of the M1, M2 and M3 seat memory switches. The key ID registration procedure should be performed while the electrical key transmitter is in the vehicle, the power switch is on (IG), and the driver door is closed. When the registration is completed, the buzzer will sound as an answerback.

2. CHECK SMART ACCESS SYSTEM WITH PUSH-BUTTON START (ENTRY FUNCTION)
(a) Check the smart access system with push-button start (entry function) Operation Check.
OK:
Smart access system with push-button start (entry function) in normal.
NG -- GO TO SMART ACCESS SYSTEM WITH PUSH-BUTTON START (PROBLEM SYMPTOMS TABLE) Problem Symptoms Table
OK -- Continue to next step.
3. CHECK MEMORY AND REACTIVATION FUNCTION
(a) Turn the power switch on (IG).
(b) Using the outer mirror switch assembly, turn the mirror surface to the fully left position.
Text in Illustration
(c) Press the M1 switch while the SET switch is being pressed.
(d) Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized.
(e) Using the outer mirror assembly, turn the mirror surface to the fully right position.
(f) Press the M1 switch.
(g) Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully left position.
Result:
B -- GO TO OTHER FLOW CHART (Power Mirror Surface Position is not Memorized) Power Mirror Surface Position Is Not Memorized
C -- GO TO OTHER FLOW CHART (Power Mirrors do not Return to Memorized Position) Power Mirrors Do Not Return To Memorized Position
A -- Continue to next step.
4. READ VALUE USING TECHSTREAM (DOOR COURTESY SWITCH)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Main Body / Data List.
(e) Read the Data List according to the display on the Techstream.
Main Body
OK:
ON or OFF appears on the screen.
NG -- GO TO LIGHTING SYSTEM (Door Courtesy Switch Circuit) Door Courtesy Switch Circuit
OK -- Continue to next step.
5. PERFORM TRANSMITTER KEY RECOGNITION CODE REGISTRATION
(a) With the power switch off and the driver side door closed, press and hold the M1, M2 or M3 switch. 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.
(b) When the manual door lock switch is pressed, check that the buzzer of the front power seat switch LH sounds once (0.5 seconds).
OK:
The buzzer sounds when the registration is completed.
NG -- PERFORM ACTIVE TEST USING TECHSTREAM
OK -- Continue to next step.
6. PERFORM MEMORY DELETION
(a) Enter the following menus: Body Electrical / Main Body / Data List.
(b) After performing any of the following procedures to cut the link between the key and switch, check that the Data List for the applicable key changes to NONE.
(c) With the power switch off and the driver side door closed, press and hold the SET switch. The main body ECU (multiplex network body ECU) will enter transmitter key recognition code deletion mode.
HINT
If the memory switch is released before entering deletion mode, the memory switch will not enter deletion mode.
(d) When the manual door lock switch is pressed, check that the buzzer of the front power seat switch LH sounds twice (0.1 seconds each time).
Main Body
OK:
The Data List display for the applicable key changes to NONE.
NG -- REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) Removal
OK -- Continue to next step.
7. PERFORM MEMORY REGISTRATION
(a) After performing any of the following procedures to link the key and a switch, check the Data List to confirm that the key and switch have been linked.
(b) With the power switch off and the driver side door closed, press and hold the M1, M2 or M3 switch. 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.
(c) When the manual door lock switch is pressed, check that the buzzer of the front power seat switch LH sounds once (0.5 seconds).
Main Body
OK:
Data List shows that the key ID has been linked to a switch (M1, M2, or M3).
NG -- REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU)
OK -- Continue to next step.
8. CHECK AUTOMATIC MEMORY CALL REACTIVATION FUNCTION
(a) 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 mirror surface position automatically moves to a stored position.
OK:
Automatic memory call reactivation function is normal.
NG -- REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) Removal
OK -- GO TO OTHER FLOW CHART Wireless-linked Return Function does not Operate
9. PERFORM ACTIVE TEST USING TECHSTREAM
(a) Enter the following menus: Body Electrical / Driver Seat / Active Test.
(b) Perform Active Test according to the display on the Techstream.
Driver Seat
OK:
The buzzer sounds.
NG -- REPLACE FRONT POWER SEAT SWITCH LH Removal
OK -- Continue to next step.
10. REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU)
