Toyota Corolla (E120): Inspection
1. Windshield wiper switch assy
- Continuity check
- check the continuity of each terminal of the connector.
Front wiper switch
Standard:
Front washer switch
Standard:
- W/o intermittent time adjust: intermittent operation check
- connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (–) terminal to terminal 5 (ew) of the connector.
- Connect the battery (+) to terminal 8 (+b) of the connector, the battery (–) to terminal 5 (ew) and 6 (+s) of the connector.
- Turn the wiper switch to the int position.
- Connect the battery (+) to terminal 6 (+s) of the connector for 5 seconds.
- Connect the battery (–) to terminal 6 (+s) of the connector.
Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 5 (ew).
- W/ intermittent time adjust: intermittent operation check
- connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (–) terminal to terminal 5 (ew) of the connector.
- Connect the battery (+) to terminal 8 (+b) of the connector, the battery (–) to terminal 5 (ew) and 6 (+s) of the connector.
- Turn the wiper switch to the int position.
- Connect the battery (+) to terminal 6 (+s) of the connector for 5 seconds.
- Connect the battery (–) to terminal 6 (+s) of the connector.
Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 5 (ew).
- Operation check (washer switch)
- turn the wiper switch to the off position.
- Connect the battery (+) to terminal 8 (+b) of the connector, the battery (–) to terminal 6 (+s) and 5 (ew) of the connecter.
- Connect the voltmeter (+) terminal to terminal 7 (+1)
of the connector, the voltmeter (–) terminal to terminal
5 (ew) of the connector. Turn the washer switch
to on and off and check voltage between terminal
7 (+1) and terminal 5 (ew).
Standard: see the illustration.
2. Windshield wiper motor assy
- Lo operation check
- connect the battery (+) to terminal 1 (+1) of the connector, the battery (–) to terminal 5 (e) of the connector, and check that the motor operates at low speed (lo).
- hi operation check
- connect the battery (+) to terminal 4 (+2) of the connector, the battery (–) to terminal 5 (e) of the connector, and check that the motor operates at high speed (hi).
- automatic stop operation check
- connect the battery (+) to terminal 1 (+1) of the connector,
the battery (–) to terminal 5 (e) of the connector.
With the motor being rotated at low speed (lo), disconnect terminal 1 (+1) to stop the wiper motor operation at any position except the automatic stop position.
- Connect terminal 1 (+1) and 3 (s), and the battery
(+) to terminal 2 (b) to restart the motor operation at
low speed.
Sst 09843–18040
- Check that the automatic stop position is correct.
Standard: see the illustration.

Circuit description
The actuator motor is operated by signals from the cruise control ecu assy.
Acceleration and deceleration
signals are transmitted by changes in the duty ratio (see below).
Duty ratio:
the duty ratio is the ratio of the period of continuity in one cycle. For
example, if a is the period of co ...
Circuit description
The fuel trim is related to the feedback compensation value, not to the basic
injection time. The fuel trim includes
the short–term fuel trim and the long–term fuel trim.
The short–term fuel trim is the short–term fuel compensation used to maintain
the air–fuel ratio at stoichiomet ...
