Lexus RX (RX 350L, RX450h) 2016-2024 Repair Manual: Inspection
INSPECTION
PROCEDURE
1. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH
(a) Check the operation of the mirror surface.
NOTICE:
If the mirror surface is fully turned to the right, left, upward or downward position, the motor slips and produces a clicking noise. This is not a malfunction.
| (1) Disconnect the outer rear view mirror assembly RH connector. |
|
(2) Apply battery voltage and check the operation of the mirror surface.
OK:
| Battery Connection | Specified Condition |
|---|---|
| Battery positive (+) → Terminal 1 (MV) Battery negative (-) → Terminal 10 (M+) | Turns upward |
| Battery positive (+) → Terminal 10 (M+) Battery negative (-) → Terminal 1 (MV) | Turns downward |
| Battery positive (+) → Terminal 9 (MH) Battery negative (-) → Terminal 10 (M+) | Turns left |
| Battery positive (+) → Terminal 10 (M+) Battery negative (-) → Terminal 9 (MH) | Turns right |
If the result is not as specified, replace the outer rear view mirror assembly RH.
(b) Check the operation of the retractable mirror. (for TMMC Made)
NOTICE:
- Disconnect and reconnect the battery between each mirror position check.
- The mirror position cannot be changed manually when the battery is connected. To change the mirror position manually, the battery must be disconnected first.

| (1) Disconnect the outer mirror actuator assembly RH connector. |
|
(2) For each position: Disconnect the battery, set the mirror position by hand, connect the battery, and check the retractable mirror movement.
