Lexus RX (RX 350L, RX450h) 2016-2025 Repair Manual: Inspection

INSPECTION

PROCEDURE

1. INSPECT SHIFT SOLENOID VALVE S1

(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection Condition Specified Condition Shift solenoid valve S1 connector terminal - Shift solenoid valve S1 body 20°C (68°F) 11 to 15 Ω If the result is not as specified, replace the shift solenoid valve S1.

*a Component without harness connected (Shift Solenoid Valve S1)

(b) Connect a positive (+) lead from the battery to the terminal of the shift solenoid valve S1 connector and a negative (-) lead to the shift solenoid valve S1 body, and check that the shift solenoid valve S1 moves and makes an operating sound.

NOTICE:

When using battery voltage during the inspection, do not bring the positive (+) and negative (-) tester probes too close to each other as a short circuit may occur.

OK:

The shift solenoid valve S1 moves and makes an operating sound.

If the result is not as specified, replace the shift solenoid valve S1.

2. INSPECT SHIFT SOLENOID VALVE S2

HINT:

Refer to Inspect Shift Solenoid Valve S1.

3. INSPECT SHIFT SOLENOID VALVE SLU

(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 5.0 to 5.6 Ω If the result is not as specified, replace the shift solenoid valve SLU.

*a Component without harness connected (Shift Solenoid Valve SLU)

(b) Connect a positive (+) lead from the battery with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the shift solenoid valve SLU connector, and check that the shift solenoid valve SLU moves and makes an operating sound.

NOTICE:

When using battery voltage during the inspection, do not bring the positive (+) and negative (-) tester probes too close to each other as a short circuit may occur.

OK:

The shift solenoid valve SLU moves and makes an operating sound.

If the result is not as specified, replace the shift solenoid valve SLU.
