(b) Check the M1 switch.

(1) Using the mirror master switch and mirror control switch, fully turn the mirror to the left.

(2) Press and hold down switches M1 and SET. Check that the buzzer sounds for 0.5 seconds, signaling that the outer mirror position has been recorded.

(3) Change the position of the outer mirror and then press the M1 switch. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully-turned-left position.

(c) Check the M2 switch.

(1) Using the mirror master switch and mirror control switch, fully turn the mirror to the right.

(2) Press and hold down switches M2 and SET. Check that the buzzer sounds for 0.5 seconds, signaling that the outer mirror position has been recorded.

(3) Change the position of the outer mirror and then press the M2 switch. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully-turned-right position.

(d) When the outer mirror is in the driving position: Check that the M1 and M2 switches cause the outer mirror to move to the recorded outer mirror positions under these conditions: turn the ignition switch LOCK, open the driver side door and press the M1 or M2 switch within 20 seconds.

(e) Check that the following procedures will erase the recorded outer mirror positions of the M1 and M2 switches: press and hold the power seat control switch; disconnect the battery's negative (-) terminal cable; and wait for at least 1 minute.

(f) Confirm that all recorded outer mirror positions are erased. Then attempt to record the outer mirror position by pressing and holding the SET switch and 2 other switches (M1 and M2). Check that no outer mirror positions are recorded by individually pressing M1 and M2 and making sure that the outer mirror does not move.

2. CHECK POWER RETRACTABLE MIRROR

(17) Press the retract switch.

(18) Check that the retracted position mirror moves to the driving position.

(c) Check the operation of the outer mirror body in relation to retract switch operations and ignition switch position changes.

(1) When the mirror body is operating, turn the ignition switch LOCK. Check that the mirror operation does not stop and continues until the operation has finished.

(2) Repeat the step above. This time, before the mirror operation completes, turn the ignition switch ACC and press the retract switch. Check that the mirror operates in the opposite direction.

(d) Check the operation of the outer mirror body when it is restrained by an obstacle.

(1) When the mirror body is moving to the retracted or driving position, restrain the mirror body by hand. Check that the mirror stops moving.

(2) With the mirror body stopped partway, push the retract switch. Check that the mirror body moves in the opposite direction.

3. CHECK REVERSE SHIFT-LINKED OPERATION OF MIRRORS

(a) Turn the ignition switch to ON.

(b) Set the outer mirror switch assembly (mirror master switch) to R or L.

(c) Check that the mirror faces downward when the shift lever is moved to R.
