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

INSPECTION

PROCEDURE

1. INSPECT SOLENOID (SL) VALVE

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

*a Component without harness connected (Solenoid (SL) Valve)

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

If the result is not as specified, replace the solenoid (SL) valve.

2. INSPECT SOLENOID (SLT) VALVE

(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 solenoid (SLT) valve.

*a Component without harness connected (Solenoid (SLT) Valve)

(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 solenoid (SLT) valve connector, and check that the solenoid (SLT) valve 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 solenoid (SLT) valve moves and makes an operating sound.

If the result is not as specified, replace the solenoid (SLT) valve.
