INSPECTION

PROCEDURE

1. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Power Slide Type)

*a

Component without harness connected

(Power Window Regulator Motor Assembly)

*b

Clockwise

*c

Counterclockwise

*d

Motor Gear

(a) Check the operation of the power window regulator motor assembly.

(1) Apply battery voltage to the power window regulator motor assembly.

(2) Check that the motor gear rotates smoothly as follows.

OK:

Measurement Condition

Specified Condition

Battery positive (+) → 2

Battery negative (-) → 1

Motor gear rotates clockwise

Battery positive (+) → 1

Battery negative (-) → 2

Motor gear rotates counterclockwise

If the result is not as specified, replace the power window regulator motor aassembly.

2. INSPECT NO. 1 BACK POWER WINDOW RELAY (except 3UR-FBE)

(a) Remove the No. 1 power window relay from the engine room relay block.

(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:

Tester Connection

Condition

Specified Condition

3 - 4

When battery voltage is not applied between terminals 1 and 2

Below 1 Ω

When battery voltage is applied between terminals 1 and 2

10 kΩ or higher

3 - 5

When battery voltage is not applied between terminals 1 and 2

10 kΩ or higher

When battery voltage is applied between terminals 1 and 2

Below 1 Ω

If the result is not as specified, replace the No. 1 power window relay.

3. INSPECT NO. 2 BACK POWER WINDOW RELAY

(a) Remove the No. 2 power window relay from the engine room relay block.

(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:
